When moving from a very sheltered aquaculture site to a very exposed oceanic aquaculture site, the energy increases proportionally in a continuum. Lojek et al. (in review) considered the primary influential parameters (water current, wave height, wave period, wavelength and water depth) which influence the species, structure, technology, methods, and operational aspects of any aquaculture endeavour and investigated six possible indices which cover these variables. Added to advanced computer modelling, assisted by detailed and constant environmental monitoring, it may be possible to refine site selection, structure selection and design, species selection, equipment and logistic requirements and health and safety requirements. This manuscript has selected two indicative indices: Specific Exposure Energy (SEE) index and Exposure Velocity (EV) index from the potential equations provided by Lojek et al. (in review) and compared them with known operational aquaculture sites highlighting present structural capability and limitations. The two indices are also utilized to reflect on their suitability for assessing sample sites with respect to biological, technological, operational or maintenance aspects of aquaculture activities. The indices have shown themselves to be useful tools in the general assessment of the energy that will influence the species and structure selection at potential aquaculture sites. This information can help prospective fish farmers characterize their sites concisely and accurately to consultants, regulators, equipment vendors, and insurance brokers. [ABSTRACT FROM AUTHOR]

Aquaculture in exposed and/or distant ocean sites is an emerging industry and field of study that addresses the need to improve food security along with the challenges posed by expansion of urban and coastal stakeholders into nearshore and sheltered marine waters. This move necessitates innovative solutions for this industry to thrive in high-energy environments. Some innovative research has increased understanding of the physics, hydrodynamics, and structural requirements enabling the development of appropriate systems. The blue mussel (Mytilus edulis), the New Zealand green shell or green lipped mussel (Perna canaliculus), and the Pacific Oyster (Magallana gigas), are the primary targets for commercial exposed bivalve aquaculture. Researchers and industry members are actively advancing existing structures and developing new structures and methodologies for these and alternative high-value species suitable for such conditions. For macroalgae (seaweed) cultivation, such as sugar kelp (Saccharina latissimi), oar weed (Laminaria digitata), or kelp sp. (Ecklonia sp.), longline systems are commonly used, but further development is needed to withstand fully exposed environments and improve productivity and efficiency. In marine finfish aquaculture, three primary design categories for open ocean net pens are identified: flexible gravity pens, rigid megastructures, closed pens, and submersible pens. As aquaculture ventures into more demanding environments, a concerted focus on operational efficiency is imperative. This publication considers the commercial and research progress relating to the requirements of aquaculture’s expansion into exposed seas, with a particular focus on the cultivation of bivalves, macroalgae, and marine finfish cultivation technologies and structural developments.

Abstract A reliable and cost‐effective source of fingerlings is essential for the successful commercial aquaculture of black sea bass. This study aimed to determine the effects of nursery tank stocking densities on the growth performance, feed efficiency, survival, tolerance to shipping, and biochemical quality of juvenile black sea bass. In two experiments, different stocking densities were compared for black sea bass at different stages of development. In Experiment 1, intermediate stage juveniles (1.27 g mean wt) were stocked at densities of 4.5 and 6.5 fish per liter of tank volume. Growth performance and biochemical quality were similar between the two density treatments. In Experiment 2, early post‐metamorphic stage juveniles (mean wt. = 0.524 g) were compared using the same stocking densities. While the fish reared at 4.5 fish/L were slightly larger, there were no significant differences in growth performance or biochemical quality between the density treatments. After both experiments, the fingerlings from each density treatment showed high survival rates under acute crowding and simulated shipping conditions. The study demonstrates that high NT densities of 4.5 and 6.5 fish/L did not negatively impact the growth performance and quality of black sea bass fingerlings, providing transport‐ready fingerlings in a relatively short period.

The overall goal of our research was to develop an embryonic stem cell line from red drum, Sciaenops ocellatus. These experiments were conducted to support future production of cell-based cultivated seafood products as a means towards meeting the growing global demand for sustainable seafood. Our hypothesis was that characteristics of embryonic stem cells, such as high proliferation and pluripotency, would facilitate development of a continuous cell line that could eventually be directed toward a muscle cell phenotype. We isolated embryonic stem cells from fertilized red drum eggs at the blastomere stage. These cells were seeded into culture wells at 50,000 cells/well. We tested various media, supplements, growth factors, and plate coatings to achieve growth of red drum embryonic cells. Cells at isolation reacted positively with the stem cell markers, OCT4, Nanog, and Sox2. Our cells had a fibroblast-like appearance and were maintained in culture for more than 43 days before senescence. Over time, most of the cultures showed extensive differentiation or died. The establishment of in vitro cultures of embryonic stem cell-like cells derived from red drum embryos represents progress towards developing cultured seafood products from marine fish.

Abstract Global production of marine finfish has grown in total volume of production and the number of species farmed commercially, but there has been little production in the United States of marine finfish other than salmon and red drum. For most species considered to be ready for commercialization, there are few or no farms from which to evaluate the size of the market or to estimate revenues and costs necessary to assess economic feasibility. This present study takes a first step to fill this gap with an analysis of the existing supply of 20 marine finfish species identified as candidates for commercialization in the United States, as a proxy for effective demand (the volume of a product sold at the market equilibrium price). Secondary data from 1950 (where available) through 2019 were compiled on each species, including (1) global aquaculture production, (2) US aquaculture production, (3) US commercial landings, (4) US recreational landings, and (5) imports. Current effective market demand (measured as the sum of commercial landings, farmed production, and imports) was low, totaling 36.6 million kg across the 20 species, which is equivalent to less than 23% of the annual volume sold of US farmed catfish. Commercial landings for 17 of the 20 species exhibited declines, potentially offering opportunities for farmed product to capture market share by filling the increasing gaps in supply. The variability in commercial landings provides opportunities for farms to capitalize on their advantage in supplying product with a high degree of consistency of volume, size, delivery frequency, and quality. Several unknown factors suggest the need for follow‐up studies on consumer preferences, degree of substitutability among finfish species, and effects of recreational landings on demand. An important limitation to prospective producers is the lack of species‐specific import data for the generic categories of “flounder,” “bass,” and “snapper.” This supply analysis provides a foundational analysis for prospective producers, investors, and researchers interested in commercialization of these marine species.

The production of fingerlings on a large scale is one of the biggest challenges for grouper aquaculture development. Groupers may be more susceptible to skeletal anomalies due to their complex skeleton formation ontogenesis. Such anomalies are normally associated with inadequate larviculture protocols for marine fish. The present study aimed to record the occurrence of skeletal anomalies in dusky grouper Epinephelus marginatus. Different degrees of kyphosis, lordosis, and scoliosis were identified. After the larviculture period (60 days), 42% of the dusky grouper presented skeletal anomalies. Therefore, we have concluded that the current protocol for the dusky grouper larviculture must be re-examined, especially to determine a more appropriate water flow in the tanks.

California halibut (CH; Paralichthys californicus) is a highly valued species that supports a commercial and recreational fishery along the Pacific coast of the United States. This species is considered a promising aquaculture candidate in California, with interest for both food production and stock replenishment. Culture of CH has been done on a small scale, showing that it is technologically feasible to rear this species commercially. Broodstock maturation and egg production can be accomplished without hormone therapy. Survival from egg to juvenile (~50 dph) can be as high as 30%. Juvenile growout to market size has been done on a limited basis, and it takes 3 years to reach a market size of 1 kg. There is a live market for CH in California and it is currently being supplemented by the importation of Paralichthys olivaceus. The known disease agents affecting CH are ectoparasites (i.e., Trichodina sp), endoparasites (i.e., Anisakis sp.), and bacterial agents (i.e., Pseudomonas sp.). While culture of this species is technologically feasible, research still needs to be done in certain areas in order to realize commercial readiness. These areas include: nutrition, selective breeding, development of all female populations; improved pigmentation; and developing methods for disease prevention and control. Biostratigraphy of Upper Palaeocene‐Lower Eocene Patala Formation were carried out to precisely locate P/E boundary within Upper Indus Basin Pakistan, Eastern Tethys.This study enabled us to identify smaller benthic foraminifera zones with BB1 and BB2, Planktonic foraminifera zones with P4, P5, E1 and E2, and Calcareous nanno‐plankton zones with NP9a and NP9b.The criteria used to recognize P/E boundary globally were applied to integrate these biozones, which made us to correlate locally and globally.

This study describes the effects of feeding taurine-supplemented Artemia on the growth, survival, whole body taurine content and jaw malformation rate of larval yellowtail kingfish Seriola lalandi. Larvae were fed rotifers containing no supplemental taurine from 3 to 15 day post hatch (dph) and Artemia co-enriched with taurine from 12 to 22 dph. Artemia were supplemented at concentrations of either 0, 0.8, 1.6, 2.4, 3.2 or 4.0 g of taurine L−1 during the 18 h HUFA enrichment process. Taurine content in the Artemia increased from 0.76 ± 0.04% DW in those without supplementation to 3.95 ± 0.17% DW in those supplemented at 4.0 g L−1. Survival rates of larval yellowtail kingfish were significantly lower in all taurine-supplemented treatments compared to the unsupplemented control. Growth was significantly improved in those larvae fed taurine-supplemented Artemia; however, we cannot attribute this improvement solely to taurine, as improved growth may have been a function of the reduced survival, and therefore increased prey availability, in these treatments. The whole body taurine content of larvae fed unsupplemented Artemia was significantly lower (1.85 ± 0.03% DW) than those fed supplemented Artemia, which did not differ from each other (pooled average 2.48 ± 0.03% DW), suggesting either a functional excretion mechanism is in place or that this represents the saturation value for larvae of this age. Jaw malformation rates were not affected by Artemia taurine content. The results of this research suggest yellowtail kingfish larvae may have a lower requirement and/or a reduced tolerance to excess dietary taurine than juveniles. [ABSTRACT FROM AUTHOR]

Marine finfish aquaculture is a rapidly growing subsector in the Asia-Pacific region, including Vietnam. However, in-depth information about health management practices is often inadequate. Our objective was to describe multi-species marine finfish aquaculture in northern Vietnam at the farm and species level, and identify practices that may influence fish health. Two surveys were conducted in April 2014 and April 2015 on respectively 120 and 119 farms of which 57% were the same farms, located in floating villages near Cat Ba Island in Hai Phong Province, Vietnam. Most management practices were not different between the multiple species per farm. Duration of grow-out season was part of both surveys and differed for most species between surveys, and also with findings from other studies. Most farmers did not have aquaculture related education. Few farmers recorded stocking, harvesting or mortality parameters, and there was little involvement of health professionals. Most stock originated from China, which could pose a risk on emerging diseases. Median proximity of farms was 3 m, which is a large potential for spread of pathogens between farms. There were few biosecurity practices in place to prevent pathogens from entering the farm, e.g. few farmers treated fish before stocking, and none indicated disinfection of harvesters. Overall mortality was different between species, but overall 50–75% was expected for many production cycles. This study provides a basic understanding that could inform future outbreak investigations or development of risk-based surveillance programs. Statement of relevance This is the first study that provides a basic understanding of health related factors in marine finfish aquaculture management in northern Vietnam. As the sector is growing, early interventions to adapt farmers to better practices may lead to a cascade of improvements, and may optimize and stabilize the sector as more families become dependent upon the industry for their livelihoods.

First feeding success is critical to larval marine finfish and optimization of live feed densities is important for larval performance and the economics of commercial hatchery production. This study investigated various rotifer feeding regimes on the prey consumption, growth and survival of yellowtail kingfish Seriola lalandi larvae over the first 12 days post hatch (dph). The common practice of maintaining high densities of rotifers (10-30 ind. mL−1) in the rearing tank was compared to a low density feeding technique, where 5-8 ind. mL−1 of rotifers were offered. A 'hybrid' feeding regime offered rotifers at the high density treatment until 5 dph and the lower feeding densities thereafter. There was no significant difference in larval survival (hybrid: 28.9 ± 7%, low density: 17.3 ± 5% and high density: 17.2 ± 9%) or growth (hybrid: 6.12 ± 0.18 mm, low density: 6.03 ± 0.10 mm and high density: 6.11 ± 0.23 mm) between treatments. Rotifer ingestion was independent of rotifer density throughout the trial and increased with larval age, with larvae at 4 dph ingesting 22 ± 1.5 rotifers larvae−1 h−1 and by 11 dph ingesting 59 ± 1.6 rotifers larvae−1 h−1. These data demonstrate that from first feeding, yellowtail kingfish larvae are efficient at capturing prey at the densities presented here and consequently significant savings in rotifer production costs as well as other potential benefits such as facilitation of early weaning and improved rotifer nutritional value may be obtained by utilizing lower density rotifer feeding regimes.

Abstract: Glutathione peroxidases (GPxs) protect cells against oxidative damage by catalyzing the reduction of hydroperoxides. In mammals, GPx1 is expressed in most tissues and has a wide substrate range, while GPx4 plays an important role in the reduction of complex lipid hydroperoxides in cell membranes and has been shown to be important for male fertility. These enzymes have not been well studied in marine teleosts, which accumulate large quantities of polyunsaturated fatty acids that are prone to oxidation. To better understand GPx expression and regulation in marine teleosts, we have cloned and characterized GPx cDNAs from yellowtail kingfish (YTK; Seriola lalandi) and investigated changes in gene expression in response to tert-butyl hydroquinone (t-BHQ), a redox-cycling metabolite of the common aquaculture feed additive, butylated hydroxyanisole. The putative GPx1 from YTK displayed a high degree of homology with GPx1 sequences from other vertebrates. Two putative GPx4 transcript variants were obtained from YTK liver. The GPx4 variants differed only in the amino terminal region of the predicted amino acid sequences, suggesting that the variants may be encoded from a single gene with alternative first exons. Computational analysis indicated a high probability of YTK GPx4 secretion. In cultured YTK fibroblast-like cells, t-BHQ treatment significantly induced the expression of GPx1 but not GPx4. The expression of glutamyl cysteine ligase, catalytic subunit (GCLC) was also significantly induced by t-BHQ, while the expression of the antioxidant enzymes peroxiredoxin 1 (Prx1) and Prx4 remained unchanged. The induction of GPx1 and GCLC by t-BHQ suggests that the conserved redox-sensing gene regulatory pathway known as the Keap1/Nrf2/ARE axis may be involved in regulating the expression of these genes in YTK. This work contributes towards a better understanding of the regulation of glutathione peroxidases in marine fish. [Copyright &y& Elsevier]

From a genetic resources viewpoint, emerging aquaculture species and species groups are examined mainly in terms of food use. In addition, we include species that are becoming increasingly important for biodiversity conservation and related ecotourism aspects. Together with ornamental fish species, we argue that these species are facing increasing vulnerability and warrant attention. Our intention is to raise awareness of the potential for increasing production and revenues from emerging species/species groups with an emphasis on an underlying link to biodiversity conservation and ecosystem preservation, and how this information will inform policy on access to the genetic resources and the sharing of benefits derived from their use. For food purposes, the fastest growing aquaculture sector is mariculture, and within this sector groupers and wrasses are considered to be the most important because they cater to the relatively lucrative live food fish restaurant trade (LFFRT), which is rapidly expanding in selected South-East Asian countries. In the Asian region, ecotourism is an emerging sector and a prominent fish group for this purpose is considered to be mahseer. A number of mahseer species are culturally and commercially important and are often seen as a group of indigenous species that are suitable for aquaculture. This review summarizes much of the limited information related to the patterns of use and exchange of genetic resources on emerging aquatic species/species groups, with particular reference to Asia.

The purpose of this study was to determine if concentrated algal paste could effectively replace live algae during the greenwater stage of cobia fingerling production without negative impact upon larval growth or survival. Mean cobia survival per tank from 2 dph through post weaning at 28 dph for the live algae treatment was 24.44 ± 2.43% (mean ± SD) as compared to 24.47 ± 2.48% for the algal paste treatment. Furthermore, the number of fish produced per liter for the live algae treatment was 2.44 ± 0.24 fish/L compared to 2.47 ± 0.25 fish/L recorded from the algal paste treatment. Mean fish weight for cobia weanlings from the live algae treatment was 0.417 ± 0.059 g compared to 0.411 ± 0.026 g for the algal paste treatment. These observations demonstrate that during the greenwater stage of cobia larviculture, live algae can be completely replaced with commercially available, concentrated algal paste without negative impact upon cobia growth, survival, or resultant weanling production per unit volume.

Abstract: This study examined the ontogenetic variations in lipid class composition and fatty acid partitioning between neutral and polar lipids of haddock (Melanogrammus aeglefinus) larvae in relation to changes in diet and microbial environment. Three groups of larvae were exposed to the candidate probiotic bacterium Arthrobacter sp. (RSXII) and three equivalent control groups were left unexposed. Larvae were fed rotifers between 2 and 31 days post hatch (dph), which were gradually replaced by Artemia until 45 dph and progressively weaned from live feed to a dry diet between 45 and 56 dph. Overall, the larvae grew exponentially during the course of the experiment as reflected by rates of increase in dry mass and accumulation of lipid. Proportions of arachidonic acid (20:4n-6, ARA) in haddock larvae were 3–7× higher than observed in the diets, suggesting the selective incorporation of this fatty acid in both lipid reserves and membranes. The initial proportion of docosahexaenoic acid (22:6n-3, DHA) in haddock larvae was 4.6× higher than the dietary values. However, DHA in the neutral lipids decreased markedly during larval ontogeny to proportions that reflected the dietary values. Regarding polar lipids, the proportions of DHA were markedly less variable than those recorded for neutral lipids, which supports the notion that phospholipids in fish are generally higher in polyunsaturated fatty acids (PUFA) and more resistant to changes in diet than are neutral lipids. During the transition from a diet of rotifer to a diet of Artemia, haddock larvae showed an arrested accumulation of triacylglycerols and a marked increased in ARA, presumably attributable to stimulation of immune functions due to an increase in the bacterial load in the rearing system. Finally, larvae exposed to RSXII showed a superior rate of increase in dry mass and lipid accumulation compared to control groups, suggesting that RSXII enhanced the general health of haddock larvae by modifying their bacterial microflora.

This paper estimates the current economic impact and future potential of cold-water marine finfish aquaculture in Maine. Salmon farming currently accounts for nearly 86% of the total value of state production. In 2001, 13,202 mt of Atlantic salmon, Salmo salar, were produced in Maine, generating US$63.7 million in revenue and an additional US$32.7 million in indirect and induced economic activity. In addition, alternative cold-water finfish species are under evaluation for commercial aquaculture including haddock Melanogrammus aeglefinus, Atlantic cod, Gadus morhua, and Atlantic halibut,Hippoglossus hippoglossus. Important constraints to culture of alternative species are identified through an ex-ante assessment of the early culture of haddock. Overall, capital formation is the most important constraint due to high risk and uncertainty on the rate of return to investment. [ABSTRACT FROM PUBLISHER]

For more than a century, vibriosis affects various species of economically important cultured marine fishes around the globe. The knowledge of this bacterial disease on many species of cultured fish is still lacking, but progressing. This review focuses on updated fundamental knowledge related to vibriosis including the history, taxonomy, and various epidemiological aspects such as socio-economy, clinical signs, pathological changes, diagnosis, pathogenesis, transmission, risk factors and control measures of vibriosis. This review revealed a rising prevalence of vibriosis in aquaculture, concomitant with the rapid development of this industry worldwide. Yet, information on Vibrio infection in cultured fish, particularly on the Vibrio of non-medical importance, the influence of their virulence toxins to host cells, effects of global warming and the socio-economic impacts are still scarce, and need more profound studies. Moreover, comprehensive epidemiological information on vibriosis are quite limited in many Asian countries with tropical climate, limiting the progression in control and prevention aspects of the disease. • Vibriosis affects various species of economically important cultured marine fishes. • The knowledge on this bacterial disease on many species of cultured fishes is still lacking. • This review focuses on several updated fundamental knowledge related to vibriosis in aquaculture. • The aspects including the history, taxonomy, socio-economy and various epidemiological aspects.
