We evaluated the survival and growth of 3-d post-hatch Siamese fighting fish, Betta splendens larvae, raised during 15 d in salt-free or salt-added freshwater (5 ppt using common table salt) and fed with a sequence of traditional live diets ( Chlorella sp., rotifers, and Artemia) or with one formulated diet complemented with a single or daily additions of Chlorella. The highest survival were those of natural-fed larvae, at 5 and 0 ppt (100 and 96.67 ± 5.77%), and there were no significant differences in final length and weight, although these were more variable in the case of the larvae maintained at 5 ppt. The use of table salt had a negative effect on the trophonts of the external parasitic dinoflagellate Piscinoodinium sp., which colonized the body surface of the larvae raised at 0 ppt and were absent on those kept at 5 ppt.

In this study bullseye puffer, Sphoeroides annulatus larvae were reared from hatching through to 1 or 2 months after weaning on an experimental scale in three replicate 600 L tanks and on three occasions during the spawning season (nine tanks in total). The rearing protocol used was green water ( Nannochloropsis oculata and Isochrysis sp.) 100 000 cells mL−1 from 0 to 11 days after hatch (DAH), 5-10 rotifers, Brachionus rotundiformis mL−1 from 2 to 26 DAH, 0.1-1 Artemia mL−1 from 21 to 34 DAH and weaning from 29 to 34 DAH. Survival to a month after weaning was 1%, a total of 3153 juveniles were produced with an average wet weight of 0.29 ± 0.07 g and a length of 27.5 ± 0.82 mm. [ABSTRACT FROM AUTHOR]

The spotted rose snapper (Lutjanus guttatus) is a marine fish species highly appreciated in local markets of some countries of Latin America. For this reason at first wild juveniles were captured and stocked in floating cages for aquaculture. Since the last decade the first studies about reproduction in captivity and massive juvenile production were started in order to supply continue culture. The current study presents up to date results regarding spawning, egg management and incubation and larval rearing protocols for the spotted rose snapper in Latin America. [ABSTRACT FROM AUTHOR]
