Stomachs of 1022 porbeagle sharks (Lamna nasus) ranging in size from 85-264 cm were examined from the Canadian porbeagle shark fishery and a scientific cruise in the northwest Atlantic between February 1999 and January 2001. Teleosts occurred in the majority of stomachs and constituted 91% of the diet by weight. Cephalopods occurred in 12% and were the second most important food category consumed. Pelagic fish and cephalopods comprised the largest portion of the diet in the spring while…

Eating catch of the day: The diet of porbeagle shark Lamna nasus (Bonnaterre 1788) based on stomach content analysis, and the interaction with trawl fisheries in the southwestern Atlantic (52°S-56°S).
The stomach content information obtained by scientific observers, that sampled specimens captured as by catch on-board commercial fishing vessels from 2010 to 2020 revealed that the consumption of hoki M. magellanicus and southern blue whiting M. australis increased with the total length of the porbeagle shark.
Temperature and depth associations of porbeagle shark (Lamna nasus) in the northwest Atlantic
The porbeagle (Lamna nasus) is a large fast-swimming pelagic shark found at high latitudes in both hemispheres. To examine the influence of temperature on porbeagle distribution, a detailed analysis
Quantitative diet assessment of wobbegong sharks (genus Orectolobus) in New South Wales, Australia
The diets of three species of wobbegong in New South Wales, Australia, were investigated using stomach contents from specimens caught by commercial fishers, finding that octopuses were more frequent in the diet of O. ornatus than other wob begong species, possibly through the smaller adult size facilitating capture ofOctopuses in small holes/ crevices.
Feeding Habits of Brown barracuda (Sphyraena pinguis, Teleostei) in the Coastal Waters of Gadeok-do, Korea
The feeding habits of brown barracuda were analyzed using the stomach contents of monthly samples collected from coastal waters of Gadeok-do, Korea from January to December, 1998 to show that the prey size increased with increase of fish size.
Feeding habits of the tiger shark, Galeocerdo cuvier, in the northwest Atlantic Ocean and Gulf of Mexico
Diet was assessed from 169 tiger sharks by life stage, area, and environmental factors, and fifteen prey groups were identified, with teleosts, molluscs, birds, cephalopods, and reptiles being the predominant prey categories.
Stomach content analyses of the threadfin anglerfish Lophiodes spilurus (Lophiiformes: Lophiidae) associated with deepwater shrimp fisheries from the central Pacific of Costa Rica.
While small and large-sized individuals showed a more pronounced selectivity for certain prey items, the high diversity of benthic prey items observed in intermediate-sized specimens suggest a more opportunistic foraging behavior.
Distribution and trend in abundance of the porbeagle (Lamna nasus) in the southern hemisphere
Investigation of observer data from the tuna longline fishery and other fishery survey data has revealed that there is no continuous decreasing trend in the abundance of the southern porbeagle, contrary to the declining trend reported in a limited region in the South Atlantic.
A record of porbeagle, Lamna nasus (Bonnaterre, 1788), in the Gulf of Trieste with discussion on its occurrence in the Adriatic Sea
The case of a juvenile porbeagle caught in waters off Slovenia is reported and the state of art about this species in the Adriatic Sea is commented on.
Food habits of the shortfin mako, Isurus oxyrinchus, off the southwest coast of Portugal
The shortfin mako, Isurus oxyrinchus, is caught in the eastern North Atlantic as a regular bycatch of the surface-drift longline fishery, mainly directed towards swordfish, Xiphias gladius, and stomachs showed teleosts to be the principal component of the diet, occurring in 87% of the stomachs and accounting for over 90% ofThe contents by weight.
Diet of the Silky Shark Carcharhinus falciformis (Müller & Henle, 1839) in Waters off Côte d’Ivoire (West Africa)
Aims: This study was to establish the feeding habits of silky shark Carcharhinus falciformis in waters off Côte d’Ivoire. Study design: All stomachs of the specimens were collected using a standard


Validated age and growth of the porbeagle shark (Lamna nasus) in the western North Atlantic Ocean
Growth parameters were estimated for porbeagle shark (Lamna nasus) in the northwest Atlantic Ocean on the basis of vertebral annuli and longevity calculations indicated a maximum age of 45 to 46 years in an unfished population.
Food, Feeding Habits, and Estimates of Daily Ration of the Shortfin Mako (Isurus oxyrinchus) in the Northwest Atlantic
Analyses of the stomach contents of 399 male and female mako sharks (Isurus oxyrinchus) from shark fishing tournaments held in New Jersey, New York, Rhode Island, and from longline catches taken between Cape Hatteras and the Grand Banks show bluefish is the major inshore food item.
Preliminary observations on the biology of the White Shark, Carcharodon carcharias, in South Australian waters
The seasonal and geographic distribution of three size categories of white sharks, Carcharodon carcharias ( 450 cm), is described for South Australian waters and sex ratios highly favoured females, suggesting some sexual segregation.

The blue shark is a pelagic species having a virtually circumglobal distribution in tropical and temperate seas. In the northern hemisphere, during the warmer months, they extend their range
Digestion and Food Consumption by Skipjack Tuna (Katsuwonus pelamis)
Skipjack tuna, 39–50 cm fork length, were studied during their first month in captivity in tanks 7.3 m in diameter and 1.1 m deep to study the passage of food through the alimentary canal and the content of the intestine.
Ontogenetic dietary shifts and feeding behavior of the tiger shark, Galeocerdo cuvier, in Hawaiian waters
Comparisons between the diets of tiger sharks from Hawaii and other locations indicate that ontogenetic shifts are universal in this species and that tiger sharks may be opportunistic feeders that prey heavily on abundant, easy to capture prey.

Biology of the Galapagos shark,Carcharhinus galapagensis, in Hawai'i
Catch records from the Hawai'i Cooperative Shark Research and Control Program were examined and data on the Galapagos shark,Carcharhinus galapagensis were analyzed, and ontogenetic changes in diet occurred as sharks increased in size.
