[ 1 ] - Embryonic, larval and juvenile development of tropical sea urchin, Diadema setosum

Diadema setosum (Leske, 1778), is one of the common echinoids widely distributed in the Indo-West Pacific Ocean, where it occurs from the Red Sea, Persian Gulf and the east coast of Africa to Japan, Australia and Malaysia. To investigate the developmental basis of morphological changes in embryos and larvae, we documented the ontogeny of D. setosum in a controlled laboratory condition at the In...

[ 2 ] - Development of breeding and fingerling production techniques for endangered long-whiskered catfish Sperata aor in captivity

An experiment was undertaken to develop a suitable seed production technique for Sperata aor in captivity. Naturally produced fry of aor was reared at different densities in nine nursery ponds 0.012 ha in size with an average depth of 0.8 m each. Three stocking densities tested, each of which was triplicated. Fry of aor stocked at 100,000/ha was designated as treatment-1 (T1), 150,000/ha as tre...

[ 3 ] - Effects of Salinity on Embryonic and Early Larval Development of a Tropical Sea Urchin, Salmacis sphaeroides

Effects of salinity on fertilization, embryonic stage, and early larval development and growth performances of short-spined white sea urchin, Salmacis sphaeroides were conducted under a controlled laboratory condition. The experiment was carried out with seven salinity treatments (15, 20, 25, 30, 35, 40 and 45 PSU), each of which was triplicated. Significantly highest fertilization success was ...
