“…could be explained by the species difference, or the food for copepods e.g. Isochrysis galbana in this study, but Rhodomonas baltica in other studies (Torres et al 2022, Krause et al 2017. Finally, Acartia copepods may feed on their eggs (egg predation), particularly at high densities (Vu et al 2017).…”

“…was generally low (< 3 eggs/female). The average number of eggs per female after the experiment was very low compared to Acartia tonsa (e.g., 7 -43 eggs per female/day, Torres et al 2022, Krause et al . 2017).…”

“…Indeed, the negative effect of density on the ovigerous rate of Pseudodiaptomus annandalei, a tropical calanoid copepod was observed at > 400 individual L -1 (Rayner et al 2017a). For Acartia species, the density effect on the copepod performance and production has been tested at much higher densities, from 125 to 8,000 adults L -1 for Acartia bilobata (Chintada et al 2021) and from 5,000 to 45,000 adults L -1 for A. tonsa (Torres et al 2022). The challenge is to meet a large number of copepods raised in artificial conditions for marine fish larvae rearing on a commercial scale.…”

Calanoid copepodAcartiaspecies are major live feeds for the early stages of economically important marine fish in hatcheries in Southeast Asian countries. However, rearingAcartiacopepods at high densities to increase productivity remains a major challenge. To address the issue, we conducted two experiments on 1)Acartiasp. nauplii (1000, 3000, 6000, 9000, 12000, and 15000 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 production. In general, increased density resulted in longer development time, and lowered survival and egg 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 12000 ind L-1. Egg production was very low which may be the result of high egg predation. The total eggs harvested were highest at the lowest adult density. These results are essential for the biomass production ofAcartiasp. in central Vietnam.

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.

Recent Trends in Live Feeds for Marine Larviculture: A Mini Review

et al. 2022

View full text Add to dashboard Cite

In marine larviculture, farmed larvae mainly rely on the alimentation of a group of small-sized phytoplankton and zooplankton referred to as live feed. Under the diversifying demands of human consumption and ornamental aquarium industry, new species of live feed and their innovative production methods are essential focuses for sustainable larviculture of many emerging fish and invertebrate species. The selection of proper live feed for larval feeding is based on several parameters, such as size, morphology, nutritional value, stock density, and growth rate. This review aims to highlight the biological characteristics, production approach, common larviculture applications as well as recent innovations in the aquaculture technology of live feed organisms (microalgae, ciliated protists, rotifer, Artemia, copepod, and others).
