The behaviors of \%Carassius auratus\% Linnaeus juvenile were studied by means of sound taming with baiting. It was found that the fish were sensitive to sound of 400 Hz after 5 days taming. The fish ran toward the source of sound quickly as the sound rang and then swam around the source. It took about 36 to 60 seconds for the fish coming together. It shows that before giving bait the sound stimulating should not be too long.

结合投饵用声音驯化鲫 (CarassiusauratusLinnaeus)幼鱼 ,结果表明鲫幼鱼对40 0Hz正弦波连续音反应敏感。音响驯化 5d后 ,鱼群在放声的同时迅速游向声源 ,在声源区密集并做回旋状游动 ;鱼群在 36~ 60s时间内聚集率达 90 %以上 ,这表明投饵前声音刺激不宜过长 ,30~ 60s较为适宜

Based on evaluation of the world marine ranching, the significance, necessity and feasibility of establishing marine ranching in Chinese sea area to achieve sustainable development of Chinas fishery sector are justified in this review. Some proposals are given for establishing marine ranching at the Bohai Sea. It suggests that an overall plan for the Bohai Seas marine ranching should be made first. While artificial reefs for demersal and close-to-seabed specied should be laid in deep caastal waters, artificial algae-reefs should be laid in inshore waters and bays where are suitable for marine cages, and acoustic taming marine ranches could be built along the coast of tourist cities. If act accordingly, there will eventually be reasonably distributed huge marine ranches along the Bohai Sea.

在分析世界海洋牧场发展的基础上,以中国海洋渔业保持可持续性发展为目的,论述了中国开发建设海洋牧场的意义、必要性及可行性,提出了在渤海海域建设海洋牧场的几点建议,建议对渤海水域进行整体长远规划,在近岸较深水域投放以增殖底栖和近底层鱼类为主的人工鱼礁,在适合网箱养鱼的近岸或内湾水域投放人工藻礁,在旅游城市近岸海域建设音响驯化型海洋牧场,最终在渤海海域形成布局合理的海洋大牧场。

The culture species of freshwater fisheries in China are most midwater and demersal fishes caught by traditional fishing gears and drug. However, the traditional fishing gears are always limited by environmental factors, such as substratum, depth of water, surroundings and flow etc., and the shoal of fish are required to be relatively centralized and the labor intensity of catching is great. Moreover, most reservoirs in China lie in the areas of hills and valleys, and lakes always have a large amount of float...

The culture species of freshwater fisheries in China are most midwater and demersal fishes caught by traditional fishing gears and drug. However, the traditional fishing gears are always limited by environmental factors, such as substratum, depth of water, surroundings and flow etc., and the shoal of fish are required to be relatively centralized and the labor intensity of catching is great. Moreover, most reservoirs in China lie in the areas of hills and valleys, and lakes always have a large amount of float grass, in which traveling fishing gears such as sweep net and trawl cannot be used and nets setting is limited badly. So far there are no effective methods to solve the serious problem. For improving the traditional catching techniques, attraction of common carp Cyprinus carpio and grass carp Ctenopharyngodon idellus to moving sound of 400 Hz sine wave was studied by using their biological characteristics and referring to the relational parameters of acoustic taming technology. The test was divided into two steps: (1) Training with the immovable sound of 400 Hz sine wave. Underwater microphone was set on the 2nd testing spot of underwater sound pressure. Then sound was played. And bait was cast as soon as the fish did not be attracted to swim towards sound source. Time of casting bait was set as 30 s and the amount of bait was set as 3 g that was divided into 3 times to throw into. (2) Training with the moving sound of 400 Hz sine wave. While the process of casting bait in step (1) was finished, tractor was operated immediately to draw the underwater microphone to move and the behavior of shoal was observed and their following time and following ratio was noted at the same time. The speed of tractor was set as 6.5 cm/s according to the swimming speed of common carp and grass carp and the actual conditions of laboratory. The tractor was shut up when the fish did not be attracted to swim following the sound source. Then the casting bait was begun. The amount of bait was set as 5 g that was divided into 5 times to throw into. After the process of casting bait was finished, the sound was still played for 30 s. The result indicated that fish showed a fright reaction, swimming away from the sound source when sound was played at first. But after 6 d training, common carp and grass carp swam towards the sound source rapidly when sound was played and their aggregation ratio was 100% both. After arriving to the area of sound source, the fish swam round in shoals surrounding the sound source and moved up to the surface of water. Also, common carp and grass carp could follow the sound source to move rapidly after 6 d training with moving sound and showed behavior of swimming round in shoals. The following ratio of common carp and grass carp was both 100% and the average following time was 19.8 s and 20.2 s respectively. There was no significant difference in following time between the two species ( t-test, α=0.05), which verified that common carp and grass carp were sensitive to moving sound of 400 Hz sine wave. The achievement of this research will improve the catching ratio greatly in the water areas that surroundings and substratum are bad and provide further scientific foundations for application of acoustic taming technology on freshwater fisheries and exploitation of new fishing gears and fishing methods, which will be of great importance for freshwater fisheries to have a fast, healthy and sustainable development.

目前我国淡水水域的养殖对象大多为中、底层鱼类 ,仍主要采用传统渔具捕捞。其缺点是受底质、水深、环境以及水流等因素限制 ,要求鱼群较集中 ,劳动作业强度大。为了改进传统的捕捞作业方式 ,本研究利用鱼类的生物学特性 ,参考音响驯化技术的有关参数 ,结合投饵用 4 0 0Hz正弦波连续音移动声源对鲤鱼 (Cyprinuscarpio)、草鱼 (Ctenopharyngodonidellus)进行诱引驯化试验。结果表明 ,最初放声时 2种鱼均产生惊愕反应 ,迅速离声源而去 ;但驯化 6d后 ,鲤、草鱼在放声后迅速游向声源 ,聚集率均为 10 0 %。经移动声源驯化 6d后 ,鲤、草鱼能够跟随声源迅速移动 ,跟随率均为 10 0 % ,平均跟随时间分别为 19.8s和 2 0 .2s。t检验证实 ,2种试验鱼跟随时间无显著差异 (a =0 .0 5 ) ,说明鲤、草鱼对移动声源的诱引反应敏感。本研究成果旨为音响驯化技术在淡水渔业中的应用及新渔具渔法的研制开发提供更进一步的科学依据
