Biology And Distribution Of The Macrocoelenterates Of Mississippi Sound And Adjacent Waters, W. David Burke

Gulf and Caribbean Research

Studies conducted in Mississippi Sound from April 1971 through June 1973 elucidated the seasonal and areal distribution of seven species of macrocoelenterates: Aurelia aurita (L), Chrysaora quinquecirrhu (Desor 1848), Pelagia noctiluca Forskål 1775, Chiropsalmus quadrumantus (Miiller 1859), Rhopilema verrillii (Fewkes 1887), Stomolophus meleagris L. Agassiz 1862, and Physalia physalis (L). Physical parameters presumed relevant to the distribution of each of these animals are presented. Developmental histories of certain of these forms are described.

This third supplement adds 158 titles to “A Bibliography of Anomalies of Fishes,” which was originally published in this journal in 1964; the first supplement followed in 1966 and the second supplement, in 1971. Citations now total 1498 in the series.

Penaeid Shrimp Distributions In Mobile Bay, Alabama, Including Low-Salinity Records, Harold C. Loesch

Gulf and Caribbean Research

Low-salinity records in the Gulf of Mexico area for taking Penaeus duorarum in water of 0.7‰ and 28°C, and Penaeus aztecus in water of 0.2‰ and 29.5°C were established in Mobile Bay, Alabama. Catches in Mobile Bay of approximately 20,000 each of P. aztecus and Penaeus setiferus, distributed over a 30-month period, show that P. aztecus taken in the hotter months had a wider salinity preference (5 to 30‰) than those taken in the cooler months (10 to 15‰). During the warmer months P. setiferus was most common in waters below 5‰ and during the winter months was almost …

Growth Of The Shrimp, Penaeus Aztecus, Fed A Diet Of Live Mysids (Crustacea: Mysidacea), John Ogle, Wayne Price

Gulf and Caribbean Research

Commercial brown shrimp (Penaeus aztecus) were shown to consume large numbers of mysid shrimp (Mysidopsis almyra) under laboratory conditions. Growth of shrimp fed a diet of mysids was comparable to growth of shrimp fed a diet of Artemia nauplii. It is suggested that mysid shrimp may serve as a food source for juvenile penaeid shrimp in northwestern Gulf coast estuaries.

Vegetative Morphology And Anatomy Of The Salt Marsh Rush, Juncus Roemerianus, Lionel N. Eleuterius

Gulf and Caribbean Research

The extensive rhizome development found in Juncus roemerianus makes this species unique among rushes and is a biological feature responsible, in part, for its domination of large tracts of salt marsh. Branching in certain mature plants is distinctly sympodial, while in most it is obscured by precocious development of the continuation bud and appears to be monopodial. Each vegetative unit is composed of a scaly rhizome which grows to varying lengths and then abruptly turns up at the end to become an erect shoot. A continuation rhizome consistently arises from an axillary bud in a ventral scale leaf. Transitional leaves …

Shrimp Population Densities Within Mobile Bay, Harold C. Loesch

Gulf and Caribbean Research

Brown shrimp and white shrimp populations available to the shrimp trawl in Mobile Bay were estimated on a monthly basis by two methods: one using existing commercial statistics and the other using experimental trawling. These methods produced similar estimates for brown shrimp whose peak standing crop in Mobile Bay occurred in June-July and was estimated at 200,000-300,000 pounds. Commercial landings peaked in July at about 342,000 pounds and were higher than the standing crop, indicating an extremely fast growth rate.

White shrimp data were variable, with commercial statistics indicating a crop in Mobile Bay of about 100,000 pounds from September …

Technique For Estimating Trawl Efficiency In Catching Brown Shrimp (Penaeus Aztecus), Atlantic Croaker (Micropogon Undulatus) And Spot (Leiostomus Xanthurus), Harold Loesch, James Bishop, Arthur Crowe, Robin Kuckyr, Paul Wagner

Gulf and Caribbean Research

Mark-recapture experiments conducted in a small 17.5 ha lake in Barataria Bay, Louisiana, were used to estimate the efficiency of a 4.9-m (16-foot) otter trawl in capturing brown shrimp, Atlantic croaker, and spot in water 1.5 m deep. The trawl was observed to sweep an area 2.5 m in width. Trawl efficiency was determined to be approximately one-third to one-half for brown shrimp, one-fourth for Atlantic croaker, and only 6 percent for spot.
