雜志封面為近海竹莢魚幼魚魚群，水下10米潛水拍攝
生物谷報道：最新出版的《海洋與淡水研究》2007第58卷,、第11期發(fā)表了水生所謝松光研究員與日本東京大學(xué)海洋研究所Yoshiro Watanabe教授合作的研究論文：Transport-determined early growth and development of jack mackerel Trachurus japonicus juveniles immigrating into Sagami Bay, Japan (pp 1048 1055)(洋流輸送過程對洄游入日本相模灣竹莢魚幼魚早期生長發(fā)育的影響),。這篇論文也是該期雜志的封面文章。這一研究由日本合作者提供樣品,，謝松光在國內(nèi)完成樣品分析,，論文第一單位為水生所。
竹莢魚在東海北緯28度以南,、臺灣以北的大陸架邊緣海域產(chǎn)卵繁殖,，受精卵和仔魚通過黑潮及其支流輸送到日本、韓國及我國黃渤海沿岸,，是研究洋流輸送過程對魚類早期生長發(fā)育和資源補(bǔ)充過程的理想對象,。這篇論文中，謝松光和合作者采用耳石微結(jié)構(gòu)分析方法研究了日本太平洋側(cè)沿岸竹莢魚幼魚的早期生長和發(fā)育,。結(jié)合他們之前發(fā)表的日本海測竹莢魚的研究結(jié)果,，發(fā)現(xiàn)洋流的輸送過程是決定早期生長發(fā)育和補(bǔ)充過程的關(guān)鍵因素。這一發(fā)現(xiàn)為海洋魚類資源補(bǔ)充理論提供了實證,，對竹莢魚資源的早期預(yù)報和管理也具有一定的指導(dǎo)意義,。在日本工作期間，謝松光還以竹莢魚為模型建立了魚類早期生長發(fā)育和耳石形態(tài)發(fā)育的關(guān)系,。
這一研究由日本合作者提供樣品,，水生所“百人計劃”謝松光博士在國內(nèi)完成樣品分析,，謝松光博士早年畢業(yè)于湖南農(nóng)業(yè)大學(xué)，后師從崔奕波研究員從事漁業(yè)生態(tài)學(xué)研究,，獲理學(xué)博士學(xué)位,，2001年6-9月美國Virginia Polytechnic Institute and State University訪問學(xué)者；2001- 2005年日本東京大學(xué)海洋研究所工作,。

Oceanographic conditions and transport processes are often critical factors that affect the early growth, survival and recruitment of marine fishes. Sagittal otoliths were analysed to determine age and early growth for 381 jack mackerel (Trachurus japonicus) juveniles from Sagami Bay on the Pacific coast of Japan. Two separate hatching periods (December and February–March) were identified. They originated from the spawning grounds in the East China Sea. Early growth and developmental rates of December-hatching fish were lower than those for February–March-hatching fish. It is likely that these differences were determined in the Kuroshio Current during transport from the spawning grounds to Sagami Bay, and the lower December water temperatures in the bay. Origin and hatch dates of juveniles in Sagami Bay were in contrast to previous research on Fukawa Bay, where April-or-later-hatching fish from spawning grounds in the coastal waters of southern Japan constituted about half of the juvenile population. Management of these two jack mackerel stocks needs to consider these differences in hatch date composition and spawning origins, as these differences could affect early growth and subsequent mortality.
Keywords: early life history, otolith microstructure, secondary primordium.
