“…Regarding the evaluation of the "hardiness" of the larvae using the TTI, results obtained in the present study with WB broodstock were higher than those reported by Kanazawa (1997) with 77% thermal tolerance for Pagrus major larvae and 73.90% for Lutjanus guttatus larvae from wild broodstock (Burbano et al, 2020). In larvae of the California halibut, Paralichthys californicus, an index of 1.88% was obtained at the end of the larval rearing period (Fuentes-Quesada and Lazo, 2018).…”

Anisotremus scapularis is a marine fish distributed along the Peruvian coast that is commercially important in local markets. IMARPE started research on this species aimed to condition breeders and control reproduction in captivity and avoid dependence on wild broodstock. Therefore, the present study characterized and compared the reproductive performance, quality of eggs and larvae between a first generation domesticated broodstock (F1B) and a wild broodstock (WB). The F1B and WB broodstocks were conditioned in recirculation systems (RAS) to spawn naturally from August 2021 to August 2022. The following parameters were recorded for each spawn, the total number of eggs, percentages of viable eggs and fertilization, and hatching, and biochemical analyses on each spawn were performed. Progeny from each spawning were assessed for survival activity index (SAI), and at 20 days’ post-hatch (DPH), the temperature tolerance index (TTI) was analyzed. WB had significantly higher (P<0.05) egg production, egg diameter, oil globule diameter, and SAI than those of F1B. However, the percentage of viable eggs and hatching showed significantly higher values (P<0.05) in F1B spawns. A low correlation (r<0.50) was observed between the evaluated reproductive parameters in A. scapularis broodstock; nevertheless, it was significant in some cases. No significant differences were observed in protein, lipid, carbohydrate, or ash content in eggs, but ash content in the 20 DPH larvae differed, with higher values in F1B. A principal component analysis (PCA), indicated a strong relationship between F1B broodstock eggs and fatty acids DHA, 16:0, 18:1n-9, and 18:2n-6; whereas fatty acids 18:0, 20:4n-3, 22:5n-3, and EPA had a high connection with WB eggs. At 20 DPH, F1B larvae had a strong link with 18:1n-9, DHA, and 18:2n-6; while WB larvae were found to have a high association with 16:1n-7, EPA, 22:5n-3, and ARA. Based on these results we concluded that F1B broodstock has better egg quality in terms of egg viability and hatching rate and similarity in most larval quality parameters compared to WB, making the F1 domesticated broodstock (F1B) an alternative to establish a broodstock under captive conditions and thus contributing to the aquaculture development of the species.

“…30 Fish larvae fed with copepods as a sole feed source, or in a mixed diet with enriched rotifers and/or Artemia, exhibit higher survival rates and growth rates and more desirable skin coloration than those fed with only enriched rotifers or Artemia. 31 This benefit can be attributed to the copepods' high contents of PUFAs (8.3%-24.6% EPA and 13.9%-42.3% DHA of total lipid), carotenoid astaxanthin (0.4%-1.4% of dry weight), and certain vitamins and trace elements. 21 In addition, copepod sizes range from 50 to 500 μm at the nauplius stage to 1-2 mm at the adult stage, facilitating efficient uptake by larvae at any stage of the rearing period.…”

Aquaculture is an essential source of protein and essential fatty acids for humans. However, the sustainable development of aquaculture faces numerous challenges, including a shortage of high‐quality feed and feedstuff, and a degeneration in the safety and quality of aquatic products. This review explores how the use of microalgae as an aquafeed ingredient may help to solve these problems. Microalgae are a vital food source for larval bivalves, shrimps, and fish due to their high nutritional value and suitable cell size. Particularly, bivalves rely on microalgae as a direct feed source throughout their entire life cycle. Microalgae are also indispensable food sources or nutrient supplements for secondary live prey, including rotifers, Artemia, and copepods. Microalgae containing a large amount of protein and lipid can be used as alternatives to fishmeal and fish oil in aquafeed. Moreover, microalgae are rich in ω‐3 polyunsaturated fatty acids, carotenoids, vitamins, and β‐glucan. These bioactive substances can be used as feed additives to improve the growth rate, skin coloration, antioxidant capacity, immunity, and survival rate of aquatic animals. However, the high production cost of microalgae limits its widespread application in aquaculture. Recent advancements in the technology used to culture microalgae intensively, especially fermentation technology, have significantly improved the production efficiency and decreased the production cost. Therefore, accelerating the use of microalgae as aquafeed is crucial if sustainable aquaculture is to be achieved. The review concludes by discussing the opportunities and challenges involved in integrating microalgae into sustainable aquaculture and suggests a way forward.

“…For example, calanoid copepods are ideal live feeds for fish larvae including grouper, Epinephelus sp. and cobia, Rachycentron canadum (Lee et al, 2010), snapper, Lutjanus guttatus (Burbano et al, 2020). However, the copepod supply is solely dependent on harvesting copepods from aquaculture farms (personal observations), which is not only unstable, but field‐harvest copepods may be also a source of various diseases (Bass et al, 2021).…”

Calanoid copepods Acartia species are major live feeds for the early stages of economically important marine fish in hatcheries in Southeast Asian countries. However, rearing Acartia copepods at high densities to increase productivity remains a major challenge. To address the issue, we conducted two experiments on (1) Acartia sp. nauplii (1000, 3000, 6000, 9000, 12,000, and 15,000 individuals L−1) and (2) adults (1000, 1500, 2000, and 2500 individuals L−1). We assessed key parameters for biomass production: development, survival, and egg and nauplii production. In general, increased density resulted in longer development time, lowered survival and egg and nauplii production but did not affect the size of adult males and females. Despite survival to adulthood decreasing at higher stocking nauplii densities, the number of surviving adults was highest at a stocking density of 12,000 individuals L−1. Egg and nauplii production was very low which may be the result of high predation. The total eggs and nauplii harvested were highest at the lowest adult density. These results are essential for the biomass production of Acartia sp. in central Vietnam.
