Abstract

This study estimated the technical efficiency of small-scale trawling in the Mekong Delta using a translog stochastic frontier production function model. Primary data were collected by interviewing the small-scale trawling vessels from January 2020 to May 2021 in the four coastal provinces (Soc Trang, Bac Lieu, Ca Mau, and Kien Giang) of the Mekong Delta. The results showed that the average technical efficiency of the surveyed fishermen was approximately 68.8%. Small-scale trawling vessels could increase their production by 31.2% if they operated at full technical efficiency. The captain’s fishing experience, vessel size, the number of nets on a boat, cooperation for inputs, supplies, and problem-solving, fishing registration, operation distance, and the fishing grounds were the main factors influencing the technical efficiency. To improve the technical efficiency of the trawling industry, it is necessary to focus on training the captains in fishing techniques, upgrading and converting large-scale vessels, and linking the market channels for consuming the caught fishery products.

渔业活动的技术效率:以越南湄公河三角洲小型拖网捕捞为例

本文采用超对数随机前沿生产函数模型对湄公河三角洲地区小型拖网捕捞的技术效率进行了估算。从2020年1月至2021年5月，通过采访湄公河三角洲四个沿海省份(Soc Trang、Bac Lieu、Ca Mau和Kien jiang)的小型拖网渔船收集了初步数据。结果表明，被调查渔民的平均技术效率约为68.8%。如果小型拖网渔船以充分的技术效率运行，其产量可增加31.2%。影响技术效率的主要因素是船长的捕鱼经验、渔船大小、渔船网数、投入品合作、供给合作、问题解决合作、捕捞登记、作业距离和渔场。为提高拖网渔业的技术效率，应注重对船长的捕捞技术培训，对大型渔船进行升级改造，打通捕捞水产品消费的市场渠道。

期刊介绍： The main aim of the International Journal of Ecology & Development (IJED) is to publish refereed, well-written original research articles, and studies that describe the latest research and developments in ecology and development. It also covers the many potential applications and connections to other areas of Ecological Science, economics and technology such as the use and development of mathematics/statistics in ecology or use and development of economics for ecology & development or inter-disciplinary nature of applications for Ecology & Development. International Journal of Ecology and Development is published three issues in a year in Winter, Summer and Fall.
