“…Growth and survival rate were improved in larval fish fed a mixture diet containing C. kasignete in the present study, suggesting that the nutritional profile of the live food is related to growth and survival in fish larvae, which is supported by the study of Santhanam () that the inclusion of copepod Oithona rigida results in better growth and survival of the seabass L. calcarifer larvae. Similarly, copepod‐based diets were successfully used in the early feeding up to 30 DPH of the European hake larvae culture (Nande, Pérez, Costas, & Presa, ). The poor growth and survival in seabass larvae fed live food only involving rotifer and Artemia nauplii could be a reflection of the inadequate nutritional value in food supply.…”

The copepod Cyclopina kasignete was supplemented to the Asian seabass Lates calcarifer larvae to evaluate its potential use as a live food supplement during larval rearing. Initial larval feeding began with sole rotifers as a live food from 3 to 7 days post hatch (DPH) followed by the addition of copepod, Artemia, and their combination from 8 to 21 DPH. Fish were sampled every 5 days to measure growth and food selectivity on 11, 15, 19, and 21 DPH. The larvae that were fed the combination diets involving copepods resulted in better growth, survival, and increased the essential fatty acid contents of eicosapentaenoic acid and docosahexaenoic acid. In terms of food selectivity, seabass larvae selected copepods over rotifers and Artemia for feeding. This study indicates that the potential use of copepod as a supplementary live food can improve larval fish performance and thus overcome low survival and slow growth in fish larval aquaculture. The present study demonstrates that the nutritional value of seabass larvae was improved when fed with diets involving copepods. Our finding highlights the importance of incorporating copepods into the feeding regimes for seabass larvae, which may be applicable to the culture of fish larvae for other species.

Egg specific gravity is of relevance for fish recruitment since the ability to float influences egg and larvae development, dispersal and connectivity between fishing grounds. Using zootechnics, histological approaches, optical and electronic transmission microscopy, this study describes the morphogenetic mechanism of adhesion of the oil-drop covering layer (OCL) to the oil droplet (OD) in embryos of Merluccius merluccius under physical conditions reflecting the marine environment. The herein described primordial (p)OCL is a substructure of the inner yolk syncytial layer which contains egg organella aimed to mobilize lipidic reserves from the oil drop (OD) towards the embryo blood. It is shown that the timely OD-OCL assembly is a critical morphogenetic process for embryo and larvae survival. Such assembly depends on egg buoyance because of its influence on the embryo capacity to rotate within the perivitelline space. Therefore, oil droplet adhesion (ODA) eggs are capable to complete their development while oil droplet non-adhesion eggs (ODNA) dye soon after hatching. We show that gravity-dependent egg buoyance categories exhibit different ODA/ODNA ratios (0–77%) and that relationship diminishes under incubation systems such as sprayers, that do not assure a dynamic seawater surface mixing to avoid egg desiccation. As an adaptive trait, egg gravity strongly depends on oceanic properties such as current dynamics, turbulence, oxygen, rainfall, and salinity, whose rapid changes would likely challenge the sustainability of fisheries recruitment.
