Activation of the prophenoloxidase system of the brown shrimp Penaeus californiensis Holmes)
Comparative Biochemistry and Physiology C, Comparative Pharmacology and Toxicology, 1996Abstract The prophenoloxidase (proPO) system of the brown shrimp Penaeus californiensis was activated using different preparations and inductors. In shrimp, this system is confined inside the hemocytes and can be obtained by lysing or centrifuging the cells.

Reducing discards of North Sea brown shrimp (C. crangon) by trawl modification
Fisheries Research, 2004Abstract The discarding of small (non-marketable) brown shrimp (Crangon crangon) in the North Sea brown shrimp fisheries is substantial in magnitude (circa 27,000 t/75 billion individuals annually). This work assessed the efficacy of various trawl modifications aimed at reducing small shrimp discarding. Changes to the mesh size of the codend (i.e. 16,

Gas-bubble disease in the brown shrimp (Penaeus aztecus)
Aquaculture, 1974Abstract Gas-bubble disease in larval and juvenile brown shrimp (Penaeus aztecus) is described. Stage II protozoeal, larval brown shrimp developed the disease after being placed in water warmed in a closed heater that did not allow excess gas to escape.

Characterization of brown spot disease of gulf coast shrimp
Journal of Invertebrate Pathology, 1980Abstract Adult penaeid shrimp were collected from mariculture raceways, holding tanks, and near-shore waters of Galveston Island, Texas. Those with darkly pigmented lesions were chosen for study. When observed by scanning electron microscopy, diseased cuticle shows dense populations of bacteria within a lesion, whereas normal cuticle shows a ...

The seasonal migration of the brown shrimp crangon crangon
Netherlands Journal of Sea Research, 1976Abstract Autumn-winter and spring migration of the brown shrimp are highly flexible processes in time, duration, distance and participation. Relative differences in the water temperature cause migration. The sensitiveness for this kind of stimuli varies for different categories of shrimps; berried females are on average more sensitive than non ...

Hypoxia does not promote naphthalene bioaccumulation in the brown shrimp, Penaeus aztecus
Marine Pollution Bulletin, 2008Since increased ventilation is known to be a common strategy used by aquatic animals to cope with hypoxia, we tested in present study the hypothesis that hypoxia can promote the bioaccumulation of naphthalene, a representative polycyclic aromatic hydrocarbon (PAH), in Penaeus aztecus, a penaeid shrimp subject to hypoxia and PAH contamination in the ...

Presence and significance of lithium in the brown shrimp, Crangon crangon (L.)
Comparative Biochemistry and Physiology Part A: Physiology, 19881. In female (non-ovigerous and ovigerous) brown shrimps, Crangon crangon, whole animal lithium levels are about 20% higher than in males, which indicates that lithium has a special function in the female reproductive system. 2. Decreasing lithium levels in larger males suggest that with males a substantial part of the lithium present may be passively ...

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).
