【摘要】 燕鳐是黄海沿岸重要鱼种之一。本文描述了燕鳐受精卵与仔幼鱼发育的形态特点和培育条件。 烟台崆蛔岛沿岸的燕鳐,5月底开始产卵,7月结束。人工受精在船上进行。受精卵和仔幼鱼在室内用静止水进行培育。 仔幼鱼的主要饵料是皱褶臂尾轮虫和卤虫幼体。幼体在室内水泥池(0.8立方米)进行培育。 受精卵和幼体在水温20.0—27.2℃,盐度31.28—31.74‰,pH8.32—8.52,溶氧(DO)1.52—8.32毫克/升的条件下进行培育。共育成幼鱼4801尾,到1981年9月20日,幼鱼最大全长92毫米。 1982年又进行了重复试验,共育出幼体6万余尾。更多还原

【Abstract】 The flying fish (Cypselurus agoo Temminek et Schlegel) is one of the important species of fish in costal water of Huanghai. In the present report the morphological characteristics of the development and the breeding condition of the fertilized eggs and the larvae has been described summarily.The flying fishs lay eggs from near the emd of May through July in coastal area of Kongdong Dao, Yantai. The fertilized eggs were obatained from artificial fertilization on board. The incubation of eggs. and the breeding of larvae were carried out in entirely static water.The Rotifers and the Nauplii of Artemia Salian were the main part of food for them. The larvae were breeded in a cement pool (0.8m) indear.The water temperature was 20-27.2℃, salinity 31.28-31.74%, pH 8.32 -8.52, DO. 1.52-8.32mg/l, during the breeding period. The larvae of flying fish amounted to 4,081 in number. The maximum total length was 92mm by September 20, 1981.The experiment was repeated in 1982, The larvae of flying fjsh amounted to six thousands in number.更多还原
