Larviculture and culture density research with West Indian pointed venus is relevant to restocking efforts to support the extractive fisheries from natural banks and also for the development of aquaculture.
A study aimed to determine safe levels of ammonia and nitrite to various life stages of the Amazon river prawn, based on the hypothesis that the early stages of development of M. amazonicum are more sensitive to ammonia and nitrite
Probiotics can provide needed micronutrients that prime immune responses in larval fish, thus increasing their survival in culture. Probiotic dosing can be applied via immersion, microcosm approaches and enrichment of live and formulated feeds.
Fingerling production has long been a bottleneck in the advancement of cobia culture. A coalition has validated intensive larviculture production systems and protocols that deliver 35 percent survival.
Separate family rearing can lead to tank-derived environmental effects that are statistically confounded with full-sib family genetic effects in shrimp breeding.
While Asia’s more extensive approaches for cobia larviculture are effective, more intensive methods are used in the Americas. Most facilities still rely heavily upon wild-capture broodstock.
U.S. trials indicated wild-caught pampano could be feed trained and spawned in captivity via hormonal induction. Observations of fecundity, egg fertilization rates, and spawning frequency suggested that quantities of pompano seedstock could be produced over time. Although survival during test
Progressive hatchery operators recognize the benefits of adding benthic pennate diatoms of the genera Amphora and Navicula to their larviculture tanks.
