using size at first maturity (sfm) as a biological reference point, the minimum legal size (mls) for the black clam, villorita cyprinoides was fixed at 20 mm. corresponding minimum legal weight was calculated as 3.4 g. the reproductive load and mean generation time were determined as 0.35 and 0.72, respectively. of the total quantity of clams exploited during 1996-97, 50% were juveniles. the pe...

The impact of freshwater discharges from upstream hydroelectric projects on estuarine ecology, particularly on commercial bivalves was seldom ever studied, despite the fact that they contribute substantially to local livelihoods. Such projects have been executed in many rivers of Indian Western Ghats unmindful of their ecological consequences. Through a period of the past five decades, two hydr...

Condition factor, gonadosomatic index, sex ratio and length weight relationship of Mormyrus rume, Mormyrus hasselquisti, Gnothonemus cyprinoides, Gnathonemus senegalensis and Petrocephalus bane ansorgei (Mormyridae) from Asa Lake, Ilorin, Nigeria were studied. The results showed that the condition factor range were 0.57-1.12, 0.64-1.22, 0.46-0.98, 0.66-1.18 and 0.86-1.28 in G. senegalensis, G. ...

One method that can be applied in the production of flavor enhancers is foam-mat drying using Tween 80 and maltodextrin. This research aimed to examine effect maltodextrin combination on characteristics from Megalops cyprinoides. used a factorial completely randomized design with two factors. Factor one was concentration 2%, 4%, 6%, factor 10%, 20%, 30%. The test parameters included yield, pH, ...

Lipid composition of Heterotis niloticus, Brycenus nurse, Gnathonemus cyprinoides and Sarotherodon galilaeus, which vary in scale thickness, were studied. Heterotis niloticus (very thick scales) had the lowest lipid content (13%), while G. cyprinoids (light scales) had the highest lipid content (26%). The common neutral lipids were cholesterol, free fatty acids and cholesterol esters, while dip...

Wann-Nian Tzeng, Chou-En Wu and Yu-Tzu Wang (1998) Age of Pacific tarpon, Megalops cyprinoides, at estuarine arrival and growth during metamorphosis. Zoological Studies 37(3): 177-183. The age of Pacific tarpon, Megalops cyprinoides (Broussonet), at estuarine arrival was estimated by counting otolith growth increments from specimens collected in the Gongshytyan Brook estuary of northern Taiwan ...
