摘要

本研究旨在评估方头鲈鱼养殖的技术和资金现状,为下一次方头鲈鱼养殖提出解决方案和克服发展方向做出贡献。该研究于2020年2月至5月在厚江省开展,采用精心设计的形式对44户农户进行了访谈。结果表明,平均单产为11.5±4.43吨/千m2/茬,平均利润为16.4±2350万越南盾/千m2/茬,高总生产成本为283.1±114.9越南盾/千m2/茬,其中粮食成本最高,占84.6%。效益比为0.06倍,净盈利农户占64%,净亏损农户占38%。成活率、鱼种大小、放养密度、经验、价格、FCR和池塘水位等因素影响产量和利润。目前,方头攀鲈养殖系统除了自然条件和自供鱼种优势外,还面临着资金短缺、产品产量依赖贸易商价格、产品标准、收获时间等诸多困难。

THE CURRENT STATUS OF TECHNICAL AND FINANCIAL ASPECTS IN SQUARE-HEAD CLIMBING PERCH (Anabas Testudineus) CULTURED IN HAU GIANG PROVINCE, VIETNAM
The study was conducted to assess the current status of technical and financial aspects to contribute to proposing solutions and to overcome the development directions for the square-head climbing perch culture next time. The study was carried out in Hau Giang Province from February to May 2020 through interviewswith 44 farmer households in a well-designed form. The results showed that the average yield is 11.5±4.43 tons/1,000 m2/crop, the average profit is 16.4±23.5 million VND/1,000 m2/crop, the high total production cost is 283.1±114.9 VND/1,000 m2/crop, in which the food cost is the highest with 84.6%. The benefit ratio was0.06 times and there are 64% of net profit and 38% of net loss farmers. The factor of survival rate, fingerling size, density stocking, experience, price, FCR and pond water level impacted yield and profit. Besides the advantages of natural conditions and self–supply fingerling, the squarehead climbing perch system currently faces many difficulties, such as capital shortage, product output depending on traders’ price, product standards, and harvest time.
