Effects of Packing Densities in Plastic Bags on Survival of Larvae and Fry of Helostoma temmincki (C&V)

Helostoma temmincki (C&V) larvae measuring 4.6 ± 0.6 mm total length were packed in plastic bags with oxygen at stocking densities of 0, 250, 500, 1000 and 1500/liter. Fry measuring 2. 0 cm ± 0.2 were similarly packed at densities of 0, 125, 250, 500 and 750/litre. The fish were observed for...
