The present paper deals with the study of the gonadal dovelopment of groy mul-lets. It is aimed at knowing whether the grey mullets can spawn or not in given condi-tions. The characteristics or oocytes in different stages of development were noticed. 1. The cycle of the sexual maturity of the grey mullets is in accordanco withthe development of the gonad. First maturation of the fish is at the third year andthe spawning time is between November and December. 2. The growth and development of grey mullets in the Xinglin Wan are similar tothose in Florida,but they are faster than those in the Mediterranean Sea and the Black Sea. 3. The grey mullets in the closed Xinglin Wan require artitificial injection withhypophyses to promote their maturation. 4. The ovaries of the Ⅱ, Ⅲ, Ⅳ and Ⅳ-Ⅱ stages, were examined in 104 femalesamples. 5. The gonad is absorbed after December, because the fish are isolated from thespawning ground in the open sea. The process of absorption is taken place from the lastten days of November to January and February next year.

本文报道了对厦门郊区封闭的海湾杏林湾普通鲻鱼性腺的组织学观察结果。观察结果表明,普通鲻鱼成熟系数变化周期和性腺发育情况相一致,首次成熟年龄为3岁,成熟时间在11、12月。吉林湾普通鲻鱼生长发育与美国的相似,而比地中海、黑海的同种鱼要快。普通鲻鱼大生长期卵母细胞吸收过程分三个阶段,从11月下旬开始,延续到翌年1—2月结束。大生长期的卵母细胞吸收过程主要依靠滤泡上皮细胞活性提高,产生分泌物质促进透明层、胶质层和卵母细胞内含物的分解,滤泡上皮细胞还直接吞噬卵黄颗粒。

This paper reports the results of the experiment in optomotor reaction about five young fishes, grey mullet (Mugil cephalus), perch (Lateolabrax japonicus), porgy (Sparus latus), carp ( Cyprinus carpio) and grass carp (Ctcnopharyngodon idellus).Reaction rate of these fishes decreases as the intensity of illumination weakens or the screen rotary velocity increases. Upper followable stimulus frequency (UFSF) rises with the intensity of illumination. Under 10~2 Ix, grey mullet's UFSF is as high as 37/sec...

This paper reports the results of the experiment in optomotor reaction about five young fishes, grey mullet (Mugil cephalus), perch (Lateolabrax japonicus), porgy (Sparus latus), carp ( Cyprinus carpio) and grass carp (Ctcnopharyngodon idellus).Reaction rate of these fishes decreases as the intensity of illumination weakens or the screen rotary velocity increases. Upper followable stimulus frequency (UFSF) rises with the intensity of illumination. Under 10~2 Ix, grey mullet's UFSF is as high as 37/sec ; perch's 26/sec ; porgy's, 27/sec ; carp's. 24/sec and grass carp's, 29/sec. Transitional illumination from scotopic to photopic vision is 10~0—10~1 Ix for grey mullet; 10~(-2)—10~(-1) Ix for perch and porgy; 1.0~(-1)—10~0 Ix for carp and grass carp. The stimulus frequency and illumination have a little influence on latent perirod. Following angular velocity is, on the whole, less than screen rotary velocity, i.e. the following rate is less than 100%, and it decreases as rotation velocity rises. Illumination has little effect on following rate. The reaction of these fishes to moving strips consists of three stages: following, actiwely swimming and no responding.

对鲻鱼(Mugil cephalus)、鲈鱼(Lateolabrax japonicus)、黄鳍鲷(Sparus latus)、鲤鱼(Cyprinus carpio)和草鱼(Ctenopharyngodon idellus)5种幼鱼进行了视觉运动反应实验。反应率随照度的降低或屏幕转速的提高而下降。高限可跟刺激频率随照度而提高,在10~2lx下,鲻鱼达37次/秒,鲈鱼26次/秒,黄鳍鲷27次/秒,鲤鱼24次/秒,草鱼29次/秒。明暗视过渡照度值:鲻鱼10~0—10~1lx,鲤鱼和草鱼10~(-1)—10~0lx,鲈鱼和黄鳍鲷10~(-2)—10~(-1)lx。照度和刺激频率对反应潜伏期有一定影响。跟随角速度普遍落后于屏幕角速度,即跟随率低于100%,并且随屏幕转速提高而下降。照度对跟随率无明显影响。几种幼鱼对运动条纹的反应可分为三阶段:跟随、活泼运动、无反应。

The paper reports that the change of Golgi bodies in number during the oocyte maturation in grey mullet, before and after carp pituitary extract and leuteinizing hormone releasing hormone analogue (LHRH-A)treatment. A lot of Golgi bodies are located between yolk granules and below radio zone before hormone treatment. No change of Golgi bodies in number and nuclear position was observed by 6 and 12h after the first injection of carp pituitary extract. Golgi bodies in number obviously decreased , and no...

The paper reports that the change of Golgi bodies in number during the oocyte maturation in grey mullet, before and after carp pituitary extract and leuteinizing hormone releasing hormone analogue (LHRH-A)treatment. A lot of Golgi bodies are located between yolk granules and below radio zone before hormone treatment. No change of Golgi bodies in number and nuclear position was observed by 6 and 12h after the first injection of carp pituitary extract. Golgi bodies in number obviously decreased , and no change of nuclear position was observed by 24h after hormone injection. The nucleus of oocyte moved to animal polar was noticed and number of oil globes in the cytoplasm decreased 8h after the secondary injection LHRH-A. The mergence of many oil globes become large oil globes by 12h after LHRH-A injection. At the end ,matured oocyte became round in shape and only a few Golgi bodies and oil globes left before spawning. These results suggest that the physiological maturation of the hormone induced oocyte may be influences completed by way of exerting on the Golgi bodies and nuclear positions.
