摘要

本研究旨在测试三种放养密度：100、200和300 ind m-3（分别为D100、D200和D300）对短吻小蠊的存活、生长（重量和总长度）和条件因子的影响。在为期六周的试验结束时，这些鱼的生存、生长和状况没有显著差异。结果表明，该种在培养条件下具有较高的适应性。次优的库存密度会产生对基础设施的次优使用，并降低生产系统的盈利能力。根据目前的研究，建议放养密度为300 ind m-3，以提高水产养殖基础设施的盈利能力，用于观赏或保护目的。

Short-tailed pipefish (Microphis brachyurus) juvenile culture: effect of stocking density on growth, survival and condition factor

The present study aimed to test the effect of three stocking densities: 100, 200, and 300 ind m-3 (D100, D200, and D300, respectively) on survival, growth (weight and total length), and condition factor of Microphis brachyurus. At the end of the six-week trial, there were no significant differences in the fish's survival, growth, and condition. The results suggest that this species presents high adaptability under culture conditions. A suboptimal stocking density generates a suboptimal use of infrastructure and decreases the production system's profitability. Based on the present study, a stocking density of 300 ind m-3 is recommended to increase the aquaculture infrastructure's profitability for ornamental or conservation purposes.

期刊介绍： Latin American Journal of Aquatic Research- LAJAR is the continuation of the journal Investigaciones Marinas (1970-2007) and is published since 2008 by the Escuela de Ciencias del Mar, Facultad de Ciencias del Mar y Geografía of the Pontificia Universidad Católica de Valparaíso. LAJAR is an “Open Access” journal that publishes in English language, original research articles, reviews and short communications on aquatic science, which contain the results of research conducted in aquaculture or in oceanic and coastal marine waters of Latin America. The following topics are considered: Physical Oceanography, Chemical Oceanography, Marine Biogeochemistry, Marine Pollution and Toxicology, Marine Geology and Geophysics, Biological Oceanography, Fisheries and Aquaculture.
