Steller sea lion, Steller’s sea lion, northern sea lion: Scientific Name: Eumetopias jubatus: Body Size: Steller sea lions weigh about 21 kg when born (male pups are usually larger than female pups, with males weighing 22 kg and females 20 kg). between diet and the probability of being pregnant within individual scat samples This data set contains Steller sea lion diet data based on analysis of scats collected during summer (May-September) and winter (November-April) rookeries and haulouts in Alaska during 1990 to 2009. Here we present a preliminary analysis of the distribution of sea lions and the prey composition of their diet; and how both relate to pollock biomass distribution. Steller Sea Lions find a wide variety of food to consume in the water. pollock which is a staple in Steller sea lion diet both winter and summer from the Gulf of Alaska up to the central Aleutian Islands area. The animals are also provided with varied enrichment, including toys, … Australian Sea Lion – Males are dark brown with a light yellow mane around their heads. Their diet may vary seasonally depending on the abundance and distribution of prey. the distribution of cetaceans and Steller sea lions (SSL; Eumetopias jubatus). relationship between diet and pregnancy, regardless of the proportions of pregnant The relative importance of pollock in the diet of Steller sea lions in Southeast Alaska was not expected. Most of the collections are from sites on the northern coast of Washington where Steller sea lions are most common and abundant. ... Sea Lion Care. They also kill harbor seals, ringed seals, younger northern fur seals and other animals. Steller Sea Lion – the largest of the species in the world. significant portion of the sea lion diet in Southeast Alaska. We sought to test two hypotheses: 1) diet in Southeast Alaska is the most diverse of all regions inhabited by Steller sea lions; and 2) pollock is not an important content prey are consumed) or quantity (as occurs during (January - April) at multiple haulouts. There was also concern that perhaps fishermen were competing with Steller sea lions for the resources that were available. No more than 540 CSL and 176 SSL over the 5-year period of the permit. California sea lions have also been known to cooperate with other species while feeding, including dolphins and seabirds. They will feed on a wide variety of seafood, including squid, clams, salmon, anchovy, dogfish, herring, lamprey, and whiting. When these giants thunder ashore, their favored beaches, called rookeries, disappear under their numbers. All Conservation Status. The steller sea lion is the largest sea lion and largest of all the eared seals, with males reaching 2200 pounds (1000 kg) and more than 10 feet (3 m) long. This plot describes the change in nitrogen isotopes (y-axis) for an individual sea lion pup over time, as measured along the length of its whiskers (or vibrissae, x-axis). Spotted Seal. Steller Sea Lion. The diet of Steller sea lions changed from capelin, herring, eulachon, and sandlance to pollock, cod, and hake. From 1993 to 1999, The National Marine Mammal Laboratories' California Current Ecosystem Program (AFSC/NOAA) collected fecal samples from Steller sea lions in Washington to examine their diet. • Mainstem Columbia River from river mile 112 (I-205 bridge in Portland) to river mile 292 (McNary Dam). Discerning the diet and patterns of prey use by Steller sea lions (SSL) is fundamental to isolating the mechanisms driving population health. Project Description. Diet /Feeding. Sea lions consume large quantities of food at a time and are known to eat about 5–8% of their body weight (about 15–35 lb (6.8–15.9 kg)) at a single feeding. Steller sea lion diet and foraging using chemical signatures, Alaska Fish and Game. Center study that found diet composition was significantly different between haulouts This work builds on a preliminary Alaska SeaLife stress levels between pregnant and non-pregnant adult females through the final trimester Sea lion, meat (Alaska Native), Steller contains 120 calories per 100 g serving. Steller sea lions are generalist predators that eat a variety of large, marine fishes (Pacific Cod, Pollack, salmons, … and non-pregnant females, using a particular haulout. Our project will further evaluate The animals were fed strict diets of herring and/or eulachon, and then blubber samples were analyzed using the QFASA method to establish a unique set of calibration coefficients for Steller sea lions and northern fur seals. Sea lions require a complex diet, and each animal receives different vitamins and supplements based on their age, needs, and medical history. Steller sea lions for­age for food along the shore­line and near pelagic wa­ters and are con­sid­ered op­por­tunis­tic hunters. Significant differences in sea lion diet were found among regions, seasons, and years, suggesting it is strongly influenced by local and temporal distributions and abundances of prey. Discerning the diet and patterns of prey use by Steller sea lions (SSL) is fundamental to isolating the mechanisms driving population health. In the win­ter, wall­eye pol­lock and Pa­cific cod are their main food source. What they will eat depends on the season and what part of their distribution area that they live in. The Western stock of Steller sea lions was placed on the endangered species list in 1997, and despite years of research, the cause behind their continued decline remains unclear. J. Aquat. unclear. Nutritional stress implies that . Our goal was to determine the diets of Steller sea lions in Southeast Alaska. • Any tributary to the CR that includes spawning habitat of … Nitrogen levels from the whisker pulled in November are in red, and from the whisker pulled in April are in blue. diet, diet diversity, Eumetopias jubatus, Hokkaido, Steller sea lion 1 | INTRODUCTION Steller sea lions (SSLs; Eumetopias jubatus) travel to the coast of Hokkaido Island, Japan, to overwinter (Nishiwaki, 1967). Steller Sea Lion. Steller sea lion diet composi-tion varied seasonally, annually, and spatially. In addition to increased predation and the junk food hypothesis, declining within Resurrection Bay but no difference was detected in birthing probability between Continued research on Steller sea lion diet and foraging identify pregnant females and subsequently track and compare diet composition and The vertical line indicates birth, with values to the left in utero and to the right post-birth.

It is the sole member of the genus Eumetopias and the largest of the eared seals (Otariidae). Here we evaluate the frequency of occurrence (FO) of prey species in 3,412 scats of adult female and juvenile SSL collected during 1999-2009, across the range of the U. S. Western Stock. Fish. The seasonal and regional patterns in prey consumption, as well as known geographic distributions and estimated body size of their primary prey, indicate that Steller sea lions … Sea lions require a complex diet, and each animal receives different vitamins and supplements based on their age, needs, and medical history. The males can be as long as 11 feet and weigh 2,500 pounds. "Diet diversity of Steller sea lions (Eumetopias jubatus) and their population decline in Alaska: a potential relationship."

They also re-examined some previously published work using harbor seals as a … UA is committed to providing accessible websites. They are almost 1 m long. Here we evaluate the frequency of occurrence (FO) of prey species in 3,412 scats of adult female and juvenile SSL collected during 1999-2009, across the range of the U. S. Western Stock. They also eat octopus, squid, gastropods and bivalves. Most of the collections are from sites on the northern coast of Washington where Steller sea lions are most common and abundant. Hake and salmonids were the most commonly identified prey in scats collected during the summer (breeding season), whereas hake and skate were most common in the non-breeding season.
