The length-weight relationship, food habits and condition factor of wild juvenile milkfish in Sri Lanka
(Elsevier, 1986)
Wild juvenile milkfish (Chanos chanos) were obtained from Negombo lagoon in September 1984. Thirty-one specimens (92–186 mm FL) had a fork length-body weight relationship of log W = −5.6083 + 3.2598 log L. These fish were ...
Collection of naturally-spawned milkfish eggs in floating cages
(Asian Fisheries Society, 1986)
Natural spawnings of milkfish from floating cages were obtained from different stocks of 5-7 year-old milkfish in 1980, 1981, 1983 and 1985. The maximum number of eggs collected in 1980, using a series of 1-m diameter ...
The effects of water hardness on the hatching and viability of silver carp (Hypophthalmichthys molitrix) eggs
(Elsevier, 1987)
An investigation was conducted to establish water hardness concentration for optimum hatching of silver carp (Hypophthalmichthys molitrix) eggs. Eggs were incubated for 19 h at 26.5°C at six levels of water hardness: 100, ...
