长期因库水深、库底杂物多、渔政管理乱等造成水库捕鱼难的桃源县,今年来,根据渔业技术资料,结合本地水库渔业捕捞情况,利用原有渔具,开展了捕捞新技术的研究与实验。使用定置网笼捕捞技术,收到了鲜鱼产量成倍增长的可喜效果。掌握“三情”,实行“二改”。我县水库渔业,过来是人放天养,常规捕捞,结果投入得不到相应的产出,严重阻碍着水库渔业的发展。为了寻求捕捞新法,我们在调查中发现:开展水库捕捞必须掌握“三情”,即库情(库水深杂物多难捕,特别是保蓄水不能放水捕捞)、鱼情(鱼类活动时未捕,而冬季蜷伏却大捕)、行情(冬季集中捕鱼上市,鱼多价低)。针对“三情”,实行了“二改”:即改冬季 This year, according to the fishery technical data, combined with the fishing in local reservoirs, the use of the original fishing gear to carry out the fishing of new technologies Research and experiment. The use of fixed-cage fishing technology has received encouraging results with doubled production of fresh fish. Grasp the “three conditions”, the implementation of “two changes.” In our county reservoir fishery, people come here to feed and catch in a routine manner. As a result, they can not get the corresponding output, which seriously hinders the development of reservoir fishery. In order to seek a new law of fishing, we found in the survey: “Three conditions” must be grasped for reserving reservoirs, that is, the reservoir conditions (that is, it is difficult to catch deep debris, especially if the stored water can not catch water and fish), fish Not caught, but the winter crouching but big catch), Quotes (winter concentrated fishing market, fish multi-low price). For “three sentiments”, the implementation of “two changes”: that change the winter
