Optimizing purse seine fishing operations in the Java Sea, Indonesia

In order to compete with others, fishermen adopt several fishing technics and tactics, and hence, occasionally, fishermen's' responses to environmental changes exceed the requirements. Thus, it is argued that this phenomenon will threaten sustainable fisheries activity. To manage fisheries to be sustainable, we need a study on the factors that influence the success of fishing operations and management. To answer this problem, we have conducted a research on purse seine fishing gear in Rembang, Central Java Indonesia. The results of this study showed that three factors affect purse seine fishing catches, i.e. length of trip (p < 0.01), ice (p < 0.01), and the cost of supplies for fishing operations (p < 0.05). However, the length of trip (days), ice (blocks) and the cost of supplies for fishing operations (Rp.) have a variable input utilization (VIU) number of less than 1. In order to optimize purse seine fishing operations, it is essential to reduce the policy of a fishing trip, ice and the cost of supplies for fishing operations.
