Habits Of Juvenile Fishes In Two Rhode Island Estuaries, Mohammed Saeed Mulkana

Gulf and Caribbean Research

The basic purpose of this work was to gain information on the possible role of some Rhode Island estuaries as nursery grounds for young migrant and resident species of fishes.

The areas selected were, the lower Pettaquamscutt River and the lower Point Judith Pond, both in the town of Narragansett, Rhode Island. The seining operations were carried through summer and early fall of 1962 when these estuaries are heavily used as nursery grounds. Major features of the occurrence, abundance and distribution of young fishes were deduced by examining samples from seine hauls. Thirty-six species were recorded from the lower river …

Oyster Abundance In Apalachicola Bay, Florida In Relation To Biotic Associations Influenced By Salinity And Other Factors, R.W. Menzel, N.C. Hulings, R.R. Hathaway

Gulf and Caribbean Research

From June 1955 through May 1957, stations on three oyster reefs were sampled quantitatively at intervals and all oysters and associated macroscopic organisms were recorded per unit area. Station I was a privately leased “natural” reef, consisting of higher places exposed at low water, with a salinity range of 22.7-36.6 o/oo and was fairly productive. Station II, depth ca. two meters, was the least saline, range 1.2-29.3 o/oo, and was considered very productive for natural reef. Station III, depth one meter, salinity range 7.5-35.7 o/oo, was depleted although there was an abundant spatfall.

A Bibliography Of Anomalies Of Fishes, Supplement 1, C.E. Dawson

Gulf and Caribbean Research

The original bibliography (Gulf Res. Repts. 1 (6), 1964) has, reportedly, been of considerable value to workers interested in the teratology of fishes and other vertebrates. The present supplement is the first of a proposed series which will attempt to include all new and pertinent publications as well as those which have previously been overlooked. The overall usefulness of the bibliography should be enhanced by its maintenance on a relatively current basis. Supplements will be issued irregularly and will normally include 75 to 100 new citations.

Studies Of Annual Abundance Of Postlarval Penaeid Shrimp In The Estuarine Waters Of Mississippi, As Related To Subsequent Commercial Catches, J.Y. Christmas, Gordon Gunter, Patricia Musgrave

Gulf and Caribbean Research

Several workers and several lines of evidence have shown that the shrimp life cycle is very short, probably about 15 to 16 months, for the very small fraction reaching the largest adult size. Additionally, a great deal of commercial fishing is carried out upon sub-adult populations within the bays and shallow Gulf. In fact most shrimp that are caught have never spawned. These shrimp grow up within one warm season and they are derived from larvae which make their way to inside waters from the offshore spawning areas. Thus, it has been surmised for a long time that prediction of …
