Diel activity of the pink shrimp Penaeus duorarum

Hydrobiologia, 1979
Twelve juvenile pink shrimp, Penaeus duorarum Burkenroad, were tested individually for 3-day periods in electronic shuttleboxes to determine their diel patterns of locomotor activity, in relation to a natural summer photoperiod. Nocturnal activity was twice that exhibited during the daytime; however, a bimodal pattern was evident with crepuscular peaks

Long-term ammonia toxicity to the pink-shrimp Farfantepenaeus paulensis

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2009
Juvenile pink-shrimp Farfantepenaeus paulensis were exposed (75 days) to NH(3) (0.016-0.287 mg L(-1)) under static condition with water renewal every 24h. Experiments were performed at 20 degrees C, at a water salinity of 15 ppt, and at pH 7.8. Endpoints analyzed were survival, growth and predation rates. After 75 days of exposure, survival was >or=90%

Localization of DDT in the body organs of pink and white shrimp

Bulletin of Environmental Contamination and Toxicology, 1970
p. 329-332. ; Shrimp collected from bays along the Texas and Florida coasts were exposed to low concentrations of DDT. The accumulated residues were compared with residues in natural populations. The DDT was found to localize in the hepatopancreas, which is removed before human consumption, posing no threat to human health.

Aspects of the Biology of the Tortugas Pink Shrimp, Penaeus duorarum

Transactions of the American Fisheries Society, 1960
Abstract On the Tortugas grounds, off southern Florida, the female pink shrimp (Penaeus duorarum) had an estimated winter growth of 5 counts per pound per month (number of shrimp per pound with heads off). The males grew 7 counts per pound per month. The shrimp were tagged with Petersen disc tags.

An Examination of Fishing Location Choice in the Pink Shrimp Fishery

Marine Resource Economics, 1986
This article analyzes fishing location choices made by pink shrimp (Pandalus jordani) fishermen fishing off the coast of northern California. Data were gathered for 17 commercial vessels making 3000 net sets over a season. A simple multiplechoice logit model was used to examine whether recent information on success in various regions aids in explaining

Thermoregulatory behavior of the pink shrimp Penaeus duorarom Burkenroad

Hydrobiologia, 1979
Twelve juvenile pink shrimp.Penaeus duorarum Burkenroad, were tested individually for 3-day periods in electronic shuttle-boxes (Ichthyotrons) to determine their thermoregulatory capabilities (temperature preference and avoidance behavior). The shrimp thermoregulated more precisely at night, which was their active period (they were more than twice as ...

Movement of Pink Shrimp in Relation to the Tortugas Sanctuary

North American Journal of Fisheries Management, 1986
Abstract More than 42,000 adult and juvenile pink shrimp (Penaeus duorarum) were tagged and released on the Tortugas (Florida) fishing grounds in 1982-1983 in order to study shrimp movement in relation to the Tortugas sanctuary. For the first time, returns per unit of effort were used in addition to conventional vector analysis to indicate the ...

Fatty acids in raw and processed alaska pink shrimp

Journal of the American Oil Chemists' Society, 1970
AbstractThe fatty acid composition of lipids extracted from whole raw shrimp, raw meat, blanched meat, canned meat and peeler waste was determined by gas liquid chromatography. The analyses revealed 29 fatty acids with chain lengths ranging from 12 to 24 carbon atoms and with 0 to 6 double bonds.

Spatial distribution of extractable organohalogens in northern pink shrimp in the North Atlantic

Biological Trace Element Research, 1999
Extractable organohalogens (EOX) are organic compounds that contain chlorine, bromine and/or iodine, which can be separated from the matrix by liquid/liquid or liquid/solid extraction. A combination of instrumental neutron activation analysis (INAA) and solvent extraction methods has been developed for the determination of EOX from the shrimp Pandalus ...

Maturation and Spawning of the Pink Shrimp, Penaeus duorarum Burkenroad

Transactions of the American Fisheries Society, 1961
Abstract A description is given of the anatomy of the reproductive system of male and female pink shrimp, Penaeus duorarum. Four stages of female maturation (undeveloped, developing, nearly ripe, and ripe) were observed using ovum size frequency, gross observation, and ratio of gonad weight to tail weight.
