Survey of Juvenile Food and Game Fish - Fisheries Investigations in the Aransas-Copano Bay System

Abstract

In October, 1961, at the Mission Bay sample station, the spotted sea trout, Cynoscion nebulosus, reached a peak of density of 81 fish per acre. The following month, at the same station, this number dropped to 9.0 fish per acre or 89.9 per cent reduction. Whether this decline is a result of mortality or reduced availability has not been determined, but the former is suspected. Seine samples produced insufficient numbers of redfish, Sciaenops ocellata; drum, Pogonias cromis; flounder, Paralichthys lethostigma; and sheepshead, Archosargus probatocephalus, to derive needed information on abundance or mortality.
