摘要

育苗阶段对石斑鱼养殖至关重要，影响成活率、生长性能和经济可行性。本研究评估了三种具有经济价值的石斑鱼物种：豹珊瑚石斑鱼（Plectropomus leopardus）、座头石斑鱼（Cromileptes altivelis）和褐大理石石斑鱼（Epinephelus fuscoguttatus）在90天育苗期的养殖性能和经济可行性。结果表明，褐大理石斑鱼成活率最高（82.5 %），生长性能最高，末长（12.32 cm）和体重（14.02 g）最显著。但其饲料系数最高（FCR = 2.81），饲料效率较低。斑马鱼生长平衡，饲料利用率最低（2.00），是最具成本效益的饲料利用方式。财务分析显示，豹珊瑚石斑鱼的盈利能力最高，净现值（NPV = 65,067美元）和内部收益率（IRR = 91.70 %）最高，投资回收期最短（1.45年）。敏感性分析表明，饲料成本和市场价格波动对财务可行性有显著影响。研究结果表明，豹珊瑚石斑鱼是苗圃生产中最有利可图的物种，具有最高的收入、利润、净现值和内部收益率。然而，棕色大理石石斑鱼的单位生产成本最低，使其成为精打细算的农民的可行选择。棕色石斑鱼在长度和重量方面增长最快，而豹珊瑚石斑鱼在保持竞争力的增长性能的同时也具有最高的市场价值，使其成为最具经济优势的选择。为了提高石斑鱼养殖的财务弹性，未来的举措应最大限度地提高饲料效率，尽量减少死亡率，并采用可持续的水产养殖做法。

Culture performance and financial business of leopard coral (Plectropomus leopardus), humpback (Cromileptes altivelis), and brown-marbled (Epinephelus fuscoguttatus) grouper nursery

The nursery phase is critical in grouper aquaculture, influencing survival rates, growth performance, and economic feasibility. This study evaluates the culture performance and financial viability of three economically valuable grouper species: Leopard coral grouper (Plectropomus leopardus), humpback grouper (Cromileptes altivelis), and brown-marbled grouper (Epinephelus fuscoguttatus) over a 90-day nursery period. Results showed that brown-marbled grouper exhibited the highest survival rate (82.5 %) and growth performance, achieving the most significant final length (12.32 cm) and body weight (14.02 g). However, it also had the highest feed conversion ratio (FCR = 2.81), indicating lower feed efficiency. Leopard coral grouper demonstrated a balanced growth rate with the lowest FCR (2.00), making it the most cost-effective feed utilization. Financial analysis revealed that leopard coral grouper had the highest profitability, with the most significant net present value (NPV = US$ 65,067) and internal rate of return (IRR = 91.70 %), along with the shortest payback period (1.45 years). Sensitivity analysis indicated that feed costs and market price fluctuations significantly influenced financial viability. The research's findings show that leopard coral grouper is the most profitable species for nursery production, having the highest income, profit, net present value, and IRR. However, brown-marbled grouper has the lowest production cost per unit, making it a feasible option for budget-conscious farmers. While brown-marbled grouper grew the fastest in terms of length and weight, leopard coral grouper maintained competitive growth performance while also having the highest market value, making it the most economically advantageous option. To improve grouper farming's financial resilience, future initiatives should maximize feed efficiency, minimize mortality rates, and employ sustainable aquaculture practices.

期刊介绍： Aquaculture Reports will publish original research papers and reviews documenting outstanding science with a regional context and focus, answering the need for high quality information on novel species, systems and regions in emerging areas of aquaculture research and development, such as integrated multi-trophic aquaculture, urban aquaculture, ornamental, unfed aquaculture, offshore aquaculture and others. Papers having industry research as priority and encompassing product development research or current industry practice are encouraged.
