Hormone level differences are generally accepted as the primary cause for sexual dimorphism in animal and human development. Levels of low molecular weight metabolites also differ between men and women in circulating amino acids, lipids and carbohydrates and within brain tissue. While investigating the metabolism of blue crab tissues using Phosphorus-31 Nuclear Magnetic Resonance, we discovered...

In the Atlantic and Gulf states, the crab pot fishery overlaps with much of the habitat of the diamondback terrapin, Malaclemys terrapin. The exclusively estuarine terrapin can be found throughout the coastal bays and creeks of the eastern and Gulf coasts of the United States. Terrapin populations can incur considerable mortality of males and juveniles when crab pots are fished in terrapin habi...

The incidence of Clostridium botulinum in fresh crabmeat of blue crab was six out of 986 samples; in pasteurized crabmeat one sample out of 1,000 contained the organism.

Rajungan (P. pelagicus, Linnaeus, 1758) merupakan salah satu komiditas perikanan yang memiliki nilai ekonomi penting sehingga banyak diminati dalam negeri maupun luar negeri. Permintaan rajungan terus meningkat berbanding lurus dengan penangkapan semakin meningkat. Tingkat pemanfaatan masih ditemukan ukuran under size tanpa memperhatikan dan kondisi habitat akan berpotensi mengurangi stok di pe...

Recent calls for the development of ecosystem-based fisheries management compel the development of resource management tools and linkages between existing fisheries management tools and other resource tools to enable assessment and management of multiple impacts on fisheries resources. In this paper, we describe the use of the Chesapeake Bay Fisheries Ecosystem Model (CBFEM), developed using th...

—Derelict (abandoned or lost) traps targeting blue crab Callinectes sapidus have the potential to affect the blue crab fishery and other marine-oriented species. We used sidescan sonar to locate derelict traps and assess their extent and accumulation rate. Experimental traps were monitored at four locations to calculate catch rates of marine organisms and trap degradation rates. In 2006, 635–67...

Hypoxia or dissolved oxygen concentrations < 2 mg/L is a problem in estuaries worldwide. In Lake Pontchartrain, a 250 km de-faunated zone exists as a result of salinity stratification and episodic hypoxia. Mature common rangia clams (Rangia cuneata) are not found within this zone. Blue crabs (Callinectes sapidus) are important estuarine predators and may move in and out of the hypoxic zone to f...
