Species Profiles. Life Histories and Environmental Requirements of Coastal Fishes and Invertebrates (Gulf of Mexico). Pigfish MAR 87
Authors:  Frederick C. Sutter; Thomas D. McIlwain; GULF COAST RESEARCH LAB OCEAN SPRINGS MS
The full text of this report is not available and therefore is not for sale. This information is provided for reference purposes only.Species profiles are literature summaries of the taxanomy, morphology, range, life history, and environmental requirements of costal aquatic species. They are designed to assist in environmental impact assessment. Pigfish are common inhabitants of warm gulf waters. Pigfish spawn during late winter and spring in open gulf waters. Young fish first appear in nearshore or estuarine environments in April to June. Juvenile pigfish may school with other species of fish (e.g. ...


Species Profiles. Life Histories and Environmental Requirements of Coastal Fishes and Invertebrates (Gulf of Mexico). Sand Seatrout and Silver Seatrout MAR 87
Authors:  Frederick C. Sutter; Thomas D. McIlwain; GULF COAST RESEARCH LAB OCEAN SPRINGS MS
The full text of this report is not available and therefore is not for sale. This information is provided for reference purposes only.Species profiles are literature summaries of the taxonomy, morphology, range, life history, and environmental requirements of coastal aquatic species. They are designed to assist in environmental impact assessment. Sand seatrout are one of the most abundant fishes in the estuarine and nearshore areas of the Gulf of Mexico. Although silver seatrout are also abundant, little research has been conducted for this species. Sand seatrout spawn in lower estuarine environments or ...


Species Profiles: Life Histories and Environmental Requirements of Coastal Fishes and Invertebrates (Gulf of Mexico). Blue Crab JUN 86
Authors:  Harriet M. Perry; Thomas D. McIlwain; GULF COAST RESEARCH LAB OCEAN SPRINGS MS
The full text of this report is not available and therefore is not for sale. This information is provided for reference purposes only.Species profiles are summaries of the literature on taxonomy, morphology, range, life history, and environmental requirements of coastal aquatic species. They are designed to assist in environmental impact assessment. The blue crab, Callinectes sapidus, is common in tidal marsh estuaries and coastal waters of the Gulf of Mexico, occupying a variety of habitats depending upon the physiological requirements of each particular stage in its life history. Spawning occurs from spring ...


Species Profiles. Life Histories and Environmental Requirements of Coastal Fishes and Invertebrates (Gulf of Mexico). Black Drum APR 86
Authors:  Frederick C. Sutter; Richard S. Waller; Thomas D. McIlwain; GULF COAST RESEARCH LAB OCEAN SPRINGS MS
The full text of this report is not available and therefore is not for sale. This information is provided for reference purposes only.This species profile is one of a series on coastal aquatic organisms, principally fish, of sport, commercial, or ecological importance. The profiles are designed to provide coastal managers, engineers, and biologists with a brief sketch of the biological characteristics and environmental requirements of the species and to describe how the species may be expected to react to environmental changes caused by coastal development. Each profile has sections on taxonomy, life ...
