越南鱼 Tilapia mossambica(Peters)在养殖条件下能够自行繁殖,产量高,管养容易,具有不少优点。可是,鱼塭(北方称养角港或海港)应否养殖越南鱼,目前还存在着争论:有人认为,鱼塭养越南鱼是增产措施之一;有人却认为,越南鱼在鱼塭中捕食其它主要养殖对象,尤其残害虾类,是鱼塭的一害。孰是孰非,一直未真正解决,以致在一定程度上妨碍了鱼塭养殖越南鱼的进一步开展。一般认为越南鱼是以植物性食料为主的杂食性鱼类。越南鱼在淡水水域的食性和养殖方法,研究者并不乏人,而关于越南鱼在鱼塭中的食性及有关养殖问题,国内未见报道。为了探讨鱼塭应否养殖越南鱼这一问题,我们进行了鱼塭中越南鱼的食性分析,并根据几年来的一些经验,提出了关于鱼塭养殖越南鱼的初步意见。
The Vietnamese fish Tilapia mossambica (Peters) is capable of reproducing itself under aquaculture conditions with high yields and easy tube care, with many advantages. However, there are still controversies regarding whether or not the fish should be farmed in the fish bowl (northern side of the harbor or seaport): Some people think that raising fish with fish is one of the measures to increase production. Some people think that the Vietnamese fish prey on the fish and shellfish Other major breeding objects, especially shrimp, are the most harmful to fish. What is right or wrong, has not really been resolved, which to some extent, hinder the further development of fish cultivation of Vietnamese fish. It is generally believed that Vietnamese fish are omnivorous fish based on plant food. There is no shortage of researchers on the feeding habits and culture methods of Vietnamese fish in freshwater waters. However, there is no report about the feeding habits of Vietnamese fish in fish and related breeding problems. In order to investigate the problem of whether or not fish should be farmed in Vietnam, we conducted a diet analysis of the fish in the fish in Vietnam. Based on several years of experience, preliminary observations were made on the cultivation of fish in the fish.
