摘要: This paper reports the growth pattern and length-weight relationship and summarizes biological data for the clearhead icesh (Protosalanx hyalocranius) in Lake Khanka (Xingkai), on the border between China and Russia. The von Bertalany growth was estimated as SL = 20.3(1 ) e )2.93 (t ) 0.21) ). The length-weight relationship was W = 0.00448 SL 2.99 for juveniles, and W = 0.000896 SL 3.59 for adults. P. hyalocranius mature in December and spawn in January, when the lake is still covered with ice, then die after spawning. The larvae hatch in March. Juveniles feed mainly on zooplankton whereas adults also feed on other fishes.
