Aceh is a province located in the western part of Indonesia, and most of its region is a coastal area that faces rapid population growth, which puts pressure on sectors like fisheries and marine resources. One of those is the West Aceh District the location of this research. Capture fisheries represent a crucial economic sector for the livelihoods of many communities, provided it is well-managed. One of the important factors contributing to the decline in fish populations is the use of environmentally harmful fishing gear. This paper aims to determine a strategy for environmentally- friendly capture fisheries management based on the code of conduct for responsible fisheries in West Aceh District, which is crucial for protecting aquatic habitat sustainability and future fish stock populations. A descriptive method combined with a survey was conducted during the research and SWOT was used as a data analysis method. The result is several important measures should be implemented in Aceh Barat District based on the code of conduct for responsible fisheries, from providing enough information and training for fishermen to enhance their knowledge and skills on sustainable fisheries management, to constructing representative fishing ports is also necessary to support efficient and environmentally friendly fishing activities, lastly, maximising the monitoring of fishing gear usage that meets the environmental standards and strengthening the law enforcement.

Fishery management is an activity that must be carried out to achieve sustainable fisheries. Fisheries management using the Ecosystem Approach to Fisheries Management (EAFM) approach is the sustainable use of fishery resources and protection of fish stocks in nature. One of the objectives of fisheries management in social and economic aspects is how fisheries can ensure the socio-economic welfare of the fishing community. Using fishing gear that is not environmentally friendly is one of the triggers for social conflict between fishermen and the uncertain selling price when the peak season of fish impacted the fishermen's economy. Therefore, the purpose of this research is to examine the socio-economic domain indicators from the aspect of EAFM-based coastal and marine resource ecosystem management. This research was conducted from January to February 2021, located in Simeulue District, Sub-District East Simeulue. The data collection method used in the study was interviews and field surveys. The determination of respondents is done by using a gradual sampling technique or stratified random sampling. Data analysis uses an ordinal-based Likert score of 1,2,3 for each indicator, namely the economic domain, fishery household income (RTP), savings ratio, asset ownership, and the social domain, namely stakeholder participation fisheries conflict and the use of local knowledge in fish resource management. Management status in East Simeulue District assessed the aggregate value of the economic domain in the medium category with a score of 48.3. Fishermen still earn less than the minimum wage, while in the social domain, it is in the excellent category with a score of 100 because fishermen, institutions, and related agencies work with each other.

Aceh is the leading province in Indonesia, where the marine protection area for juvenile sharks and rays was first established, precisely in Aceh Jaya waters. Rigaih is the fishing port located closest to Aceh Jaya waters, where the angler fish closely with the marine protected area and even intersect with the juvenile’s habitat. This study aimed to examine shark and ray catches in Aceh Jaya before and after establishing the marine protection area. We conducted landing monitoring from 2017 to 2019 (before establishing a conservation area) and monitored in 2020 when the conservation area was established. We recorded that 73% of sharks and ray caught on set gill net. The composition of sharks and rays landed at PPI Rigaih consisted of Sphyrna lewini (75%, n=1783), Chiloscyllium punctatum (8%), Neotrygon caeruleopunctata (7%, n =175), and other species (10%). This study aimed to provide scientific recommendations to support shark conservation action in Aceh Jaya Waters. We found that Aceh Jaya waters are an important area for the life stages of several threatened species, including Scalloped Hammerhead Sharks (S.lewini) and Bottlenose Wedgefish (R.australiae) that are listed in Critically Endangered and listed in Appendix II CITES. Management to support the conservation action needs to be strengthened not only limited to Marine Protected Areas but also fisheries management to reduce the incidental catch of threatened sharks and ray species. Further studies need to be conducted to delineate the habitat range of threatened shark and ray species and identify fishing behaviours that pose a risk for incidental catches of sharks and rays.

The objective of the present study was to analyze the morphometrics variation of three male fiddler crab species collected from Jaboi mangrove area, Weh island, Indonesia. A total of 50 male fiddler crab species from each species (Tubuca dussumieri, Gelasimus vocans and Austruca perplexa) were collected from three research station used digging method and direct capture. The number of morphological characters that measured was 18 characters. The water quality and soil parameters observed were salinity, pH of water and soil, water temperature, C-organic concentration in substrate and sediment type. ANOVA (confidence interval of 95%) and Discriminant Function Analysis was used for analizing the morphometric variation beetwen species. The results showed that the mangrove area of Jaboi, Weh island provides a suitable habitat characteristic for male fiddler crab. Tubuca dussumieri and Gelasius vocans tend distributed in the area with sediment type of mud, while Austruca perplexa tends distributed in the area with sediment type of sand. The result of statistical analysis showed that there were ten separate characters between Tubuca dussumieri and Gelasimus vocans, 17 separate characters between Tubtubuca dussumieri and Austruca perplexa, and 13 separate characters between Gelasimus vocans and Austruca perplexa. Morphometrics variation can be observed in the carapace, propodus, mouth, walking legs, and eye stalks.

Aceh fishermen in Ocean Fishing Port Kutaraja Banda Aceh generally carry out fishing operations around Aceh North waters which have abundant and diverse biological potential. Catches in Aceh North waters are still heavily influenced by several natural factors that often occur in certain seasons, one of which is the factor of Sea Surface Temperature (SST) based on this research about the effect of SST on purse seine catches based in Kutaraja Banda Aceh Ocean Fishery Port. This study aims to determine the catches of purse seine fishermen in Kutaraja Ocean Fishery Port to know the SST distribution, and to determine the effect of SST on purse seine catches based in Kutaraja Banda Aceh Ocean Fishery Port. This research was conducted in November 2019 at Kutaraja Ocean Fishery Port. Data analysis used in this study is purse seine catch data obtained from UPTD from 2015-2019 tabulated in tabular and graphical format, SST distribution obtained from Aqua-MODIS satellites from 2015-2019 using SeaDas software and analysis used to see the effect of SST on catch is using linear regression analysis. The conclusian is based on the results of studies on how ocean SPL affect the fish catches using purse seine with the highest vessel size of 11-20 GT in 2018 with a total of 2,499,634 kg while the lowest catch in 2016 with a total of 1,460,220 kg. SST distribution found in Aceh North waters shows that the highest temperature occurred in 2015 which was 30.24oC while the lowest occurred in 2016 which was 29.04oC. From linear regression analysis results showed that SST in Aceh North waters showed a coefficient of determination (R²) of 0.2279. This value can give a picture that the SST parameters contribute to fish catches of 22.79% and the rest is influenced by other oceanographic factors. While the correlation coefficient (r) of 0.477 means that this condition can indicate sufficient correlation have a positive

The peacock hind grouper (Cephalopholis argus) is among several highly exploited grouper fishes globally. Categorized as least concern (LC) in the IUCN, biological data on the species is limited, especially in the Aceh region. This research targeted to investigate the biological features of the C. argus fished on the northern coast of Aceh. The fish samples were collected from Pelabuhan Perikanan Samudera (PPS) Lampulo, Kuta Alam District, Banda Aceh, Aceh from June - September 2020. Overall, 30 specimens C. argus were compiled in this study. The total length (TL) varied between 136.0-284.0 mm, while weight (W) ranged between 46.5-460.0 g. In addition, Fulton's condition (K) ranged from 1.45-4.61, and relative weight (Wr) ranged from 81.75-128.53 g. The LWRs analysis revealed a b value of 3.1329 with a correlation coefficient of 0.94, indicating a positive allometric growth pattern. This study provides length-weight relationships (LWR) and condition factors value for the peacock hind grouper that will assist in building a feasible management of the fish.
