Laboratory reared fish eggs and larvae and subsequent stages from plankton of Vellar Estuary, Porto Novo: 2. The flatfish, Cynoglossus puncticeps (Richardson)

Abstract

Eggs and larvae of the flatfish, Cynoglossus puncticeps were collected from Vellar Estuary and reared in the laboratory upto 72 hr (4 stages) while the rest of the 7 stages (6 postlarvae and 1 juvenile) were collected from plankton samples. Of two batches of eggs appeared in the plankton, the first batch was from January-April (sal. 30.76-34.77 ppt; temp. 27.43-31.18 degrees C) and second from July-October (35.37-19.81 ppt; temp. 28.65-29.63 degrees C). Subsequently larvae were collected from January-December (sal. 35.78-2.25 ppt; temp. 28.38-26.68 degrees C). Larval growth and the morphometric measurements have been described
