Aquaculture serves as a source of protein and livelihood is an alternative to capture fisheries, thereby reducing pressure on the wild. However, aquaculture tends be limited by sustainability issues, which include overdependency fishmeal, high cost associated with environmental impact activities, may detrimental aquatic lives environment, use antibiotics treat diseases, have adverse effect in their host or environment. Efforts are being made toward attaining practical ways enhance...
This gonad enhancement study investigates the effect of different fresh and formulated feeds feeding regimes on growth quality wild-collected adult sea urchin, Tripneustes gratilla, under farm conditions for over 18 weeks. In first 12 weeks (phase 1), urchins were fed Ulva rigida (U); a 50:50 mixture U. Gracilaria gracilis (UG); G. (G) diet 20U (containing 20% rigida), in final 6 2) study, was changed to feed (20U diet). By end phase 1, produced gonads (50.72 ± 5.4 g) that significantly...
Water temperature and the presence of sand substrate are considered critical environmental factors affecting growth cultured sea cucumbers. This study investigated effects water temperatures or absence in tanks on N. grammatus fed an equal ration abalone waste for eight weeks. Sea cucumbers with a mean weight 8.34 g were used study. The treatments Ambient + (A S), without (A-S), Cold (C Cold-water (C–S). cold/constant was 16°C representative winter conditions while ambient/fluctuating...
Abstract The integrated multitrophic aquaculture (IMTA) of sea cucumber and abalone has been proposed as a potential bioremediation tool that stimulates increased growth. This study assessed the role stocking density frequency tank cleaning in IMTA on growth, water, sludge bioremediation. was conducted for 16 weeks made four treatments replicates; cocultured with (low density—27: 1 g [abalone (ab): (sc)]) tanks cleaned once week (L1); density) twice (L2); (high density—15:1 [ab:sc]) (H1)...
This study investigated the growth and haematological response of Clarias gariepinus to different concentration garlic supplemented diet for a period 12 weeks. was carried out in 2011 premises Fisheries Department, Delta State University, Asaba, Nigeria. The experimental formulated contain 0% (control), 0.5%, 1% 3% garlic. Fish were sorted into four groups based on fed live body weight. Diets which did not show significant effect (P = 0.06) weight C. gariepinus. However, fish diets...
