Thermal inactivation kinetics of proteases and polyphenoloxidase in brown shrimp (Crangon crangon)
Food Chemistry, 2016To optimize product quality of the cooked brown shrimp (Crangon crangon), quantitative data on the influence of all relevant process parameters (treatment time and temperature) on several quality attributes is required. Surprisingly, kinetic data and models on heat induced inactivation of important endogenous spoilage enzymes of the brown shrimp are ...

Selenium Reduces the Retention of Methyl Mercury in the Brown Shrimp Crangon crangon
Environmental Science & Technology, 2012Methyl mercury accumulated at the top of aquatic food chains constitutes a toxicological risk to humans and other top predators. Because the methyl mercury enters the aquatic food chains at the lower trophic levels, uptake and elimination processes at these levels affect the methyl mercury content at the higher levels.

Silicon utilization in the brown shrimp, Crangon crangon (L.)
Comparative Biochemistry and Physiology Part A: Physiology, 1989Abstract 1. 1. Decreasing whole animal silicon levels in larger animals indicate that relatively high silicon concentrations are present in the exoskeleton. 2. 2. Higher silicon concentrations in males and ovigerous females must be ascribed to. respectively, a size effect and the presence of eggs (and a high silicon content of the egg shells).

The effects of crude oil on enzymes in the brown shrimp (Penaeus sp)
Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1978Abstract 1. Selected enzymes of the stomach-hepatopancreas of adult brown shrimp ( Penaeus sp. ) were assayed following exposure of the shrimp to 10 ppm crude oil for 24 hr. 2. Empire Mix crude oil caused no effects on activities of any of the enzymes studied. 3.

Herbivory potential of postlarval brown shrimp associated with salt marshes
Journal of Experimental Marine Biology and Ecology, 1984Abstract Laboratory feeding experiments were used to study the herbivory potential of postlarval brown shrimp ( Penaeus aztecus Ives). Plant materials fed to shrimp included Skeletonema costatum (Greville) Cleve, Isochrysis sp., Spartina detritus, and Spartina epiphytes. A total of 16 treatments were derived from all possible combinations of

Haemolytic activity in the brown shrimp (Penaeus californiensis holmes) haemolymph
Comparative Biochemistry and Physiology Part A: Physiology, 1993Abstract 1. 1. Natural haemolytic activity in brown shrimp (Penaeus californiensis) haemolymph was detected using mouse erythrocytes as target cells. This activity is unrelated to agglutinating and phenoloxidase activity, but it is another probable component of the shrimp defence system. 2. 2.

Phosphoglucomutase Polymorphism in Brown Shrimp, Penaeus aztecus
Journal of the Fisheries Research Board of Canada, 1974Eight phenotypes of phosphoglucomutase (PGM) were detected in abdominal muscle extracts from brown shrimp (Penaeus aztecus) by starch-gel electrophoresis. The observed phenotypes were assumed to be under the control of five allelic genes. This assumption was supported by the observed distribution of phenotypes.There were no significant differences in ...

Spontaneous Necroses in Muscles of Brown Shrimp, Penaeus aztecus Ives
Transactions of the American Fisheries Society, 1970Abstract Brown shrimp (Penaeus aztecus) caught in trawls in Galveston Bay and kept in poorly aerated tanks frequently have macroscopic focal, irregular, white areas in the muscles of different segments of the abdomen. When the shrimp are placed in well aerated tanks, some of this discoloration may regress within 24 hours. Similar areas of discoloration

Mortality of Young Brown Shrimp Penaeus aztecus in Estuarine Nurseries
Transactions of the American Fisheries Society, 1989Abstract We estimated actual 2-week mortalities of postlarval and juvenile brown shrimp in a Galveston Bay salt marsh by comparing densities of cohorts throughout the spring. Mortalities ranged between 33% and 61% in 1982 and 23% and 39% in 1987. Brown shrimp mortality in predator-exclusion cages during 1987 was less than 3%.

Hermaphroditism in brown shrimp: lessons from field data and modelling
Marine Biology, 2010This study was undertaken to further clarify whether the brown shrimp, Crangon crangon (Linnaeus 1758), is a gonochorist, a facultative or an obligate hermaphrodite. Juvenile shrimps were sampled from intertidal habitats along the German Wadden Sea coast with a push net and from a power plant water inlet to quantify the share of primary females. Length-
