“…It is well established that the fatty acid composition of rotifers reflects the composition of their food [7,[14][15][16][17]. In addition, in wild zooplankton, vitamin C has been found to be derived from phytoplankton [18], and microalgae such as Chlorella and Nannochloropsis are good sources of vitamin C for rotifers [8,9]. The vitamin C contents of the tank rotifers at Miyazaki decreased markedly compared to the enriched ones although the contents of the tank rotifers at Kamiura and Kagoshima did not decrease significantly.…”

Nutritional evaluation of rotifers in rearing tanks without water exchange during seed production of amberjack Seriola dumerili

We evaluated the nutrient contents of rotifers sampled from larval-rearing tanks (tank rotifers) without water exchange during the seed production of amberjack Seriola dumerili at three facilities (Kamiura, Kagoshima, and Miyazaki) and compared them with the nutrient contents of freshly enriched rotifers. Compared to the enriched rotifers, the lipid contents, especially neutral lipids and proportion of 22:6n-3, tended to decrease in the tank rotifers. These trends were clearer at Miyazaki where the tank rotifers were sampled before daily supplementation of microalgae (Nannochloropsis). Crude protein content of the tank rotifers did not decrease markedly although the proportion of lysine tended to decrease. Vitamin C and E contents of the tank rotifers decreased significantly only at Miyazaki. Calcium content of the tank rotifers increased at Kamiura and Miyazaki, and the increases in iron and manganese contents of the tank rotifers at Miyazaki and zinc content at Kagoshima were pronounced. These results suggest that the nutritional value of rotifers in larval-rearing tanks without water exchange can be maintained by appropriate supplementation of microalgae. The effect of certain minerals that became high in tank rotifers on subsequent larval development requires further investigation.

Effect of cultivated copepods (Acartia tonsa) in first-feeding of Atlantic cod (Gadus morhua) and ballan wrasse (Labrus bergylta) larvae

et al. 2015

The aim of this study was to compare the nutritional composition and effects of short periods with cultivated copepod nauplii versus rotifers in first‐feeding. Atlantic cod (Gadus morhua) and ballan wrasse (Labrus bergylta) larvae were given four different dietary regimes in the earliest start‐feeding period. One group was fed the copepod Acartia tonsa nauplii (Cop), a second fed enriched rotifers (RotMG), a third fed unenriched rotifers (RotChl) and a fourth copepods for the seven first days of feeding and enriched rotifers the rest of the period (Cop7). Cod larvae were fed Artemia sp. between 20 and 40 dph (days posthatching), and ballan wrasse between 36 and 40 dph, with weaning to a formulated diet thereafter. In addition to assessing growth and survival, response to handling stress was measured. This study showed that even short periods of feeding with cultivated copepod nauplii (7 days) had positive long‐term effects on the growth and viability of the fish larvae. At the end of both studies (60 days posthatching), fish larvae fed copepods showed higher survival, better growth and viability than larvae fed rotifers. This underlines the importance of early larval nutrition.

“…Hence, these compounds are considered 'essential' dietary components for higher marine organisms (Kanazawa et al 1979, Castell 1982, Hapette & Poulet 1990, reviews by Sargent et al 1993Sargent et al , 1995a. In the laboratory and in aquaculture, controlled nutritional experiments have conclusively established the essential role of such dietary components for marine organisms.…”

Fecundity of the copepod Calanus helgolandicus was monitored at a coastal station in the western English Channel during January to September 1994 and varied seasonally from 3 to 33 eggs female-' d-l (mean 17 eggs female-' d-'). Particulate fatty acid levels, particularly in the <20 pm size fraction, were more highly correlated with fecundity than either chl a, particulate carbon or nitrogen. and this reflected the size and species composition of the microplankton. Diatoms, dinoflagellates and ciliates all sustained high fecundity. The mean volume of eggs produced by C. helgolandicus was inversely related to both food availability and fecundity, with increased numbers of smaller eggs produced during per~ods of high food availability. Female C helgolandicus with the highest body nitrogen and carbon produced eggs with the highest carbon and nltrogen contents, although these eggs were also smaller. Hatching viability was consistently high with a seasonal mean of 83% and both viability and the incidence of deformed nauplii were negatively correlated with the carbon and nitrogen content of females and eggs. Hatching viability was not correlated with the abundance of diatoms, but was closely correlated with the levels of 18:2(n-6) and 20:4(n-6) fatty acids in both the environment and in the eggs. Particulate concentrations of the polyunsaturated fatty acids 20:5(n-3) and 22:6(n-3), although abundant in the environment and therefore good indicators of food availability, were not correlated with either egg viability or naupliar survival. The levels of saturated and monounsaturated fatty acids in the eggs were important factors determining naupliar survival under starvation conditions. Although food availability limited fecundity, female recruitment was possibly limited by predation pressure. particularly during the late summer. This study highlights the value of seasonal and nutritional based studies in understanding variability in zooplankton fecundity.
