Oral administration of gonadotropin-releasing hormone analogue enhances previtellogenic oocyte growth of blue mackerel Scomber australasicus

, 2020
ハンドリングに弱いサバ科魚類における非侵襲的な人為催熟技術の開発を目指し，卵黄蓄積開始前のゴマサバに安価な粗精製GnRHaを経口投与した。1.2 mg/kg魚体重/日のGnRHaを20日間経口投与した結果，有意な卵濾胞径の増大が認められた。また，油球期後期の卵母細胞が経口投与区において出現し，その頻度はGnRHa徐放性ペレットの腹腔内投与（0.1 mg/kg魚体重）よりも高い傾向が認められた。以上の結果から，GnRHa経口投与がサバ科魚類の卵黄形成期以前の卵成長促進に有効であることが示唆された ...

Magnesium isotopic variation in marine fish organs

Progress in Earth and Planetary Science
Magnesium is a macro-nutrient for all living organisms, and its stable isotope ratios (δ26Mg) can be used for analyzing feeding habits and the dynamics of elements within the body. However, it was still unclear what kind of conditions for feeding and the

Carbon isotopic changes of 16 proteinogenic amino acids during trophic transfer in a cultured marine consumer

Progress in Earth and Planetary Science
Stable carbon isotopic compositions of amino acids (δ 13CAA) in organisms potentially record information on carbon sources and flow in food webs. In this study, we report δ 13C values of 16 proteinogenic amino acids in marine consumers and evaluate their
