Respuesta :
The decrease of Steller sea lions (Large number of similar jubatus) inside the Alaskan Gulf and the Hawaiian Islands could be attributable to them having to eat quite so much pollock (a gadid fish) as opposed to a more balanced and varied diet that contains fattier fishes like herring or sandlance.
From of the 1970s to the 1990s, the Western region's sea lions' diet would shift forward into higher consumption of pollock and lowered intake of herring due to a rise in pollock inhabitants and reduce in herring population.
Pollock, like tuna and salmon, is rich in proteins in saturated fat. Pollock also is low in calories and high in in B12, potassium, and selenium. Pollock contains vitamin c, iron, magnesium, potassium, sodium, potassium, and vitamin A, among other nutrients. Herring is a member of a larger family from around 200 species of fish, but the three most prevalent sardines species are Atlantic, Pacific, and Araucanian. Herrings have indeed been salted for at least 750 years in Europe to keep as cold weather food.
