Cage culture plays an important role in achieving higher output and generating more export earnings in Malaysia. However, the cost of fingerlings, feed and labour have increased substantially for cage culture in the coastal areas in Peninsular Malaysia. This paper uses farm level data gathered from Manjung, Perak and Kota Tinggi, Johor to investigate the technical efficiency of brackish water fish cage culture using the stochastic frontier approach. The technical efficiency was estimated and specifically the factors affecting technical inefficiencies of fish cage culture system in Malaysia was investigated. On average, 37 percent of the sampled fish cage farms are technically efficient. The results suggest very high degrees of technical inefficiency exist among the cage culturists. This implies that great potential exists to increase fish production through improved efficiency in cage culture management in Peninsular Malaysia. The results indicate that farmers obtained grouper fingerlings from other neighboring countries due to scarcity of fingerlings from wild sources. The cost of feeding for grouper (Epinephelus fuscoguttatus) requires relatively higher costs compared to seabass (Lates calcarifer) production in cage farms in the study areas. Initiatives to undertake extension programmes at the farm level are needed to help cage culturists in utilizing their resources more efficiently in order to substantially enhance their fish production.
网箱养殖在马来西亚实现更高产量和创造更多出口收入方面发挥着重要作用。然而，马来西亚半岛沿海地区网箱养殖的鱼苗、饲料和劳动力成本大幅增加。本文利用从霹雳州曼绒和柔佛州哥打丁宜收集的农场层面数据，采用随机前沿方法研究咸淡水鱼网箱养殖的技术效率。估计了技术效率，并特别研究了影响马来西亚鱼网箱养殖系统技术无效率的因素。平均而言，37%的抽样鱼网箱养殖场技术效率较高。结果表明，网箱养殖户中存在非常高程度的技术无效率。这意味着通过提高马来西亚半岛网箱养殖管理效率来增加鱼类产量具有很大潜力。结果表明，由于野生鱼苗稀缺，养殖户从其他邻国获得石斑鱼苗。与研究区域网箱养殖场的尖吻鲈（Lates calcarifer）生产相比，养殖石斑鱼（Epinephelus fuscoguttatus）的饲料成本相对较高。需要在农场层面开展推广计划，以帮助网箱养殖户更有效地利用其资源，从而大幅提高鱼类产量。
