摘要

石斑鱼养殖是台湾水产养殖业中发展迅速、充满活力的产业,是重要的创收来源。在较佳地点养殖鱼类(FFABL)是一种很有前景的生产策略。本研究评估了台湾石斑鱼养殖的生产和经济效益。这项调查采用了两个步骤:(1) 通过成本效益分析,确定影响利润的主要因素;(2) 通过多元统计,阐明生物因素与经济因素之间的关系。研究结果表明,杂交大石斑鱼是最佳鱼种选择,它能带来并突出正收入、可行的效益成本比和利润率。研究发现,由于杂交大石斑鱼的饲料转化率较低,其饲料管理需要更多考虑。生产者需要在生产周期内用商品饲料替代杂鱼,以确保更好的饲料管理。最后,本文认为饲料是石斑鱼养殖的主要制约因素,对饲料生产率的任何变化都很敏感,要维持台湾石斑鱼产业的发展,必须解决这一制约因素。

The Bioeconomic Analysis of Hybrid Giant Grouper (Epinephelus fuscoguttatus × Epinephelus lanceolatus) and Green Grouper (Epinephelus malabaricus): A Case Study in Taiwan
Grouper aquaculture is a rapidly growing and dynamic industry within the Taiwan aquaculture sector that serves as an important source of income generation. Farming fishes at a better location (FFABL) is a promising production strategy. This study evaluated the production and economic performance of grouper farming in Taiwan. This investigation employed two steps: (1) a cost–benefit analysis to determine the main component affecting profitability; and (2) multivariate statistics to clarify the relationship between biological and economic factors. The findings suggest that the best choice of species is hybrid giant grouper that generates and highlights a positive income, viable benefit–cost ratio and profit rate. The study found the feed management of hybrid giant groupers requires more consideration due to its low feed conversion ratio. The producers need to replace trash fish in commercial feed during the production cycle to ensure better feed management. Finally, this paper argues that feed is the main constraint for grouper farming, which is sensitive to any change in feed productivity, and this constraint must be solved to sustain the grouper industry in Taiwan.
