摘要
隐虾栖息在秘鲁和智利安第斯山脉西坡的河流中。但在阿雷基帕(秘鲁)的河流中发现的最大人口密度具有社会,经济,商业和美食的重要性。对这种虾的研究始于1950年。雄蛇具有攻击性,因为它有最发达的蹄足之一,导致更大的相互作用和同类相食。为了减少物种间的相互作用,采用了两种培养体系。对于仔鱼来说,使用微咸水可以维持较高的存活率(>85%),但仅在初始培养阶段(50 d)。对于成年雄鱼的育肥,在不同水平的单独容器中培养可提高成活率(87% - 100%)和产量(1.0 kg m - 2),使用该系统,罗非鱼也可以进行培养。仍然需要证明在半自然池塘内的单个容器中育肥雄虾的技术和经济可行性。
Management of the Interaction and Cannibalism of Postlarvae and Adults of the Freshwater Shrimp Cryphiops caementarius (Molina, 1782)
Cryphiops caementarius shrimp inhabits the rivers of the western slope of the Andes of Peru and Chile. But the greatest population densities found in the rivers of Arequipa (Peru) have social, economic, commercial, and gastronomic importance. Researches on this species of shrimp date from 1950. The males of C. caementarius are aggressive by having one of the most developed chelipeds, causing greater interaction and cannibalism. To reduce the interaction of the species, it has been used two culture systems. For postlarvae, using brackish water can maintain high survival (>85%), but only in initial culture which lasts for 50 days. For the fattening of adult males, culturing in separate containers conditioned in various levels improves the survival (87–100%) and yield (1.0 kg m − 2 ), and with this system, the culture is also performed with tilapia. It is still required to demonstrate the technical and economic feasibility of fattening male shrimp in individual containers within seminatural ponds.
