Biology and ecology of bluefin tuna by Takashi Kitagawa, Shingo Kimura

By Takashi Kitagawa, Shingo Kimura

This e-book makes a speciality of most up-to-date details at the biology and ecology of the 3 bluefin tuna species: the Pacific (Thunnus orientalis), Atlantic (T. thynnus), and southern bluefin tuna (T. maccoyii). within the e-book, the phylogeny and easy ecological details reminiscent of adolescence historical past, age and progress, and nutrients behavior are coated. info regarding migratory ecology, and critical organic facets comparable to metabolism and energetics, swimming functionality, education, visible body structure, and reproductive body structure also are incorporated.

Furthermore, new examine insights approximately different types of mathematical types for bluefin tuna ecology are brought. all of the chapters are contributed by means of energetic scientists engaged in bluefin tuna examine. The purpose of this booklet is to give a contribution to a greater figuring out of the biology and ecology of bluefin tuna, and inspire undergraduate and graduate scholars who learn this ebook to develop into bluefin tuna scientists who can give a contribution to additional realizing of the biology and ecology of bluefin tuna.

75% in all other size classes (Clemmesen 1996). 11. Relationship between standard length (SL) and the RNA/DNA ratio of three patches of fieldcaught larvae, compared to those of one day starved fish. Modified from Tanaka et al. (2008). Early Life History 37 melanostictus at first feeding, the percentage of starving larvae is zero (Kimura et al. 1996). Thus, the percentage of starving larvae in Pacific bluefin tuna appears to be relatively higher than those of other species. Although predation is generally considered to be most important factor which controls larval mortality in marine fishes (Houde 1987; Bailey and Houde 1989), starvation itself as well as the delayed response of starvation weakened larvae to predatory attack could greatly contribute to mortality in the larval period of Pacific bluefin tuna.
