Abstract

Collecting and trading of used components of purse seine in Pekalongan, Central Java, Indonesia, will minimize the impact from pollution caused by dumped fishing gear. The used components of purse seine will be repaired if possible or resold to the plastic ore factories. This study aimed to identify types and quantities of used components of purse seine in the city. Data was collected in Pekalongan City, Central Java. Data analysis was carried out to determine the type of nets materials, the total sinker of each purse seine component. In general, the used materials can be categorized into nets (webbing) consisting of repairable nets and non-repairable nets, ropes, floats, sinkers, and rings. The types of the materials of components were nylon, sponges and PVC for floats, leads for sinkers, polyethylene for ropes, and stainless steel for rings. The monthly average of the major components (i.e., nets) received by the collectors was 32,162 kg and re-sold by the collectors was 47,271 kg. Different quantities between the nets received and re-sold were due to the stock from the previous month being sold in the next month.
