Cetacean habitats in the northern Gulf of Mexico.(Statistical Data Included)
April 1, 2001... Abstract--Surveys were conducted in the northern Gulf of Mexico during the spring seasons of 1992, 1993, and 1994 to determine the distribution, abundance, and habitat preferences of oceanic cetaceans. The distributions of bottlenose dolphins...

Somatic growth function for immature loggerhead sea turtles, Caretta caretta, in southeastern U.S. waters.(Statistical Data Included)
April 1, 2001... Abstract--The Sea Turtle Stranding and Salvage Network, coordinated by the National Marine Fisheries Service through a network of state coordinators, archives data on sea turtles that strand along the U.S. coast. We conducted length-frequency...

A study of catches in a fleet of "ghost-fishing" pots.(lost fish traps)(Statistical Data Included)
April 1, 2001... Abstract--Pots are a form of trap used to capture fishes, crustaceans, or gastropod mollusks. Occasionally, these traps are lost at sea, where they have the potential to fish for many years because they are constructed of robust manmade...

Age, growth, and mortality of gray snapper, Lutjanus griseus, from the east coast of Florida.(Statistical Data Included)
April 1, 2001... Abstract--Gray snapper, Lutjanus griseus, were sampled from recreational headboat and commercial landings along the east coast of Florida, 1994-97. Fish were weighed (g) and measured (total length, TL, in mm), and sagittal otoliths were removed...

Feeding ecology of the Mediterranean spiderfish, Bathypterois mediterraneus (Pisces: Chlorophthalmidae), on the western Mediterranean slope.(Statistical Data Included)
April 1, 2001... Abstract--The feeding habits of the Mediterranean spiderfish, Bathypterois mediterraneus, the most abundant fish below 1000 m on the deep slope of the Catalan Sea (western Mediterranean), were studied. Samples were obtained at depths between...

Larval development of the kishi velvet shrimp, Metapenaeopsis dalei (Rathbun) (Decapoda: Penaeidae), reared in the laboratory.(Statistical Data Included)
April 1, 2001... Abstract--The complete larval development of Metapenaeopsis dalei (Rathbun) is described from laboratory-reared larvae. The larvae were reared in a plastic container (20 L). Larvae from the first zoeal stage to the third zoeal stage were fed...

Interannual variation in predation on first-year Sebastes spp. by three northern California predators.(Statistical Data Included)
April 1, 2001... Abstract--There is much interannual variation in numbers of first-year Sebastes that settle near shore off northern California, and when more abundant, they become prey of an increased variety of predators. Among predators that concentrate on...

Behavioral reactions of northern bottlenose whales (Hyperoodon ampullatus) to biopsy darting and tag attachment procedures.(Statistical Data Included)
April 1, 2001... Abstract--The effects of invasive or intrusive research techniques need to be thoroughly documented in order to satisfy appropriate standards of animal care. How cetaceans react to either biopsy darting or tag attachment procedures has been...

Depth distributions and time-varying bottom trawl selectivities for Dover sole (Microstomus pacificus), sablefish (Anoplopoma fimbria), and thornyheads (Sebastolobus alascanus and S. altivelis) in a commercial fishery.(Statistical Data Included)
April 1, 2001... Abstract--We estimated size-specific depth distributions and commercial bottom trawl fishery selectivities for Dover sole (Microstomus pacificus), shortspine thornyhead (Sebastolobus alascanus), longspine thornyhead (S. altivelis), and...

Yield-per-recruit analysis for black drum, Pogonias cromis, along the East Coast of the United States and management strategies for Chesapeake Bay.(Statistical Data Included)
April 1, 2001... Abstract--Black drum, Pogonias cromis, along the U.S. East Coast is subject to commercial and recreational harvest. However, prior to this study no modeling had been undertaken to examine the potential for overfishing in the Chesapeake Bay...

Adjustment of commercial trawling effort for Atlantic cod, Gadus morhua, due to increasing catching efficiency.(Statistical Data Included)
April 1, 2001... Abstract--A learning curve analysis is applied to model the change in effort units with time by the commercial fishery for Atlantic cod (Gadus morhua) in the Barents Sea. The results indicate that fishing efficiency has increased and that the...

Assessment of skipjack tuna (Katsuwonus pelamis) spawning activity in the eastern Pacific Ocean.(Statistical Data Included)
April 1, 2001... Abstract--An investigation of skipjack tuna, Katsuwonus pelamis, spawning activity was conducted to test an earlier established and widely accepted hypothesis that significant spawning of skipjack does not occur in the eastern Pacific Ocean...

Biochemical identification of shark fins and fillets from the coastal fisheries in New Zealand.(Statistical Data Included)
April 1, 2001... Abstract--The protein fingerprints of shark fillets and fins taken from commercial landings in northern New Zealand waters were compared with the protein fingerprints from control samples of ten species of coastal sharks. Isoelectric focusing...

Reproductive cycle, fecundity, and seasonal distribution of the anglerfish Lophius litulon in the East China and Yellow seas.(Statistical Data Included)
April 1, 2001... Abstract--The reproductive cycle, sexual maturity, fecundity, and seasonal distribution of the anglerfish Lophius litulon were studied from a total of 989 specimens collected in the East China and Yellow seas between March 1991 and July 1997....

Differential parasitism by Naobranchia occidentalis (Copepoda: Naobranchiidae) and Nectobrachia indivisa (Copepoda: Lernaeopodidae) on northern rock sole (Lepidopsetta polyxystra Orr and Matarese, 2000) and southern rock sole (L. bilineata Ayres, 1855) in Alaskan waters.(Statistical Data Included)
