“…Furthermore, it has been reported that the early introduction of MPDs does not enable fish larvae to fully exploit their growth potential (Kujawa et al. 2010, 2016). These diets lack feeding stimuli that can be easily detected by the olfactory rosette and trigger hormonally mediated feeding responses in fish (Volkoff et al.…”

Burbot (Lota lota maculosa) hold enormous potential for freshwater commercial aquaculture. Current larval burbot rearing involves providing live prey for initial feeding. Two trials were conducted to investigate the reduction of live prey for larval burbot. In Trial 1, five treatments were evaluated: the control group (C) received rotifers (Brachionus plicatilis) and Artemia spp. from 11‐50 days post‐hatch (DPH). Treatment one (Trt 1) had live feeds from 11‐78 DPH, treatment two (Trt 2) received only microparticulate diets, treatment three (Trt 3) fed rotifers at 11‐22 DPH and Gemma microparticulate diets at 21‐50 DPH, while treatment four (Trt 4) had rotifers at 11‐20 DPH, then co‐feeding of Artemia spp. and EZ Artemia (liquid Artemia replacement) at 21‐32 DPH, followed by EZ Artemia at 33‐40 DPH. Trial 1 revealed that providing EZ Artemia reduced the live feeding period by 17 days, but survival and growth were significantly lower compared to the control. In Trial 2, five feeding treatments were assessed: the control group (C) was the same as in Trial 1. Treatment one (Trt 1) received rotifers at 11‐25 DPH and EZ Artemia at 20‐50 DPH; treatment two (Trt 2) had Artemia spp. from 11‐30 DPH and EZ Artemia at 25‐50 DPH; treatment three (Trt 3) received only EZ Artemia; treatment four (Trt 4) had Artemia spp. at 11‐21 DPH followed by co‐feeding of Artemia spp. and Gemma Wean at 22‐32 DPH, and exclusive feeding of Gemma Wean from 33‐78 DPH. Survival rates ranged from 0% to 30.94%, with Trt 1, Trt 2, and Trt 4 reducing the live feeding period by 17‐24 days. Survival for Trt 1 and Trt 2 groups did not significantly differ from the control. Overall, these studies demonstrate that eliminating rotifers or Artemia during burbot larviculture can be achieved with minimal adverse effects on survival and growth.

“…Examples of comparable performance between cyprinid larvae fed MDs and live feeds do exist (Carvalho et al, 2006;K. Dabrowski & Poczyczy nski, 1988;Kujawa et al, 2016), as well as instances where larval survival and growth were statistically Note: Values expressed on a per-fish basis. "Additional revenue" = farmgate value × survival resulting from MD, "reduced cost" = labor and retail costs associated with feeding Artemia for 14 days, "additional costs" = retail cost associated with feeding MD for 14 days, and "reduced income" = farmgate value × survival resulting from Artemia.…”

Cultured freshwater ornamental fish are primarily fed Artemia at early life stages. Development of alternative feeding strategies could decrease the Artemia reliance of ornamental producers, reduce labor costs, and improve industry resilience by diversifying larval feeding options. In this study, Corydoras aeneus, Synodontis eupterus, Synodontis nigriventris, Epalzeorhynchos bicolor, Pterophyllum scalare, and Trichogaster lalius larvae were offered one of four diets at first feeding: newly hatched Artemia or one of three microparticulate diets (MDs). After 14 days of feeding, survival and standard length (SL) were evaluated, and partial budget analyses (PBA) were conducted to evaluate the economic feasibility of replacing Artemia with MDs. For all species except E. bicolor, at least one MD performed as well as or better than Artemia with regard to the parameters in question. E. bicolor exhibited reduced survival when fed MDs compared to Artemia, although SL did not vary significantly among treatments. PBAs indicated that replacing Artemia with MDs at first feeding resulted in an average net benefit of $0.043 ± 0.004 for all species except E. bicolor, which resulted in a net cost of $0.048. These results indicate that MDs represent a physiologically and economically feasible alternative to Artemia for larval culture of many freshwater ornamental fishes.

Nowadays, the problem of inland water pollution is acute. It is caused by vast industrial growth and agricultural intensification. Concentrations of Cd, Pb, Zn, Cu, Mn, Fe, Mg, and Kwere determined in the muscles, liver, and gonads sabrefish from Rybinsk Reservoir areas with different anthropogenic loads. The tissue samples were analyzed by atomic absorption spectrometry. Heavy metals accumulated more intensively in the body of fish from more polluted areas of the reservoir. Among the analyzed elements, the maximum accumulation levels were found for K, Zn, and Fe and the minimum levels were observed for Cd and Pb. The gonads contained the largest concentration of Cd and Mn, the muscles contained the highest concentrations of Mg, and the other elements mainly accumulated in the liver of sabrefish. The THQ and HI values for all elements did not exceed 1, which suggests that there is no potential non-carcinogenic risk to human health. The target values of carcinogenic risk (TR) for cadmium ranged from 8.32 × 10−6 to 1.22 × 10−4 in the muscles. The increased content of cadmium in the gonads of sabrefish not only poses a risk to human health, but also to the reproduction of this species in the Rybinsk Reservoir.
