Abstract

Whale shark (Rhincodon typus) is the largest fish species in the world and is classified as endangered. This study is crucial for the conservation of this species and developing effective conservation strategies. The research was conducted in the Botubarani waters, Gorontalo Province. Individual whale shark identification was performed using Photo ID, including the identification of sex and wound location. Photo IDs were processed using the Interactive Individual Identification System (I3S) software and includes information related to the ID, body length, and the time the individual was previously identified. Monitoring of the location, number, timing of whale shark presences and water parameters, was carried out through direct field observations. The results showed that 5 whale shark individuals were identified, all of which were male, with lengths ranging from 4.5 to 4.8 meters, and 1 individual had visible wounds. From 78 days of monitoring, Whale sharks were observed for 70 days and not observed for 8 days. The frequency of whale shark appearances ranged from 1 to 4 individuals per day. Whale sharks in Botubarani waters exhibited site fidelity and a mixed migration pattern. The intensity of their presence is quite high. This intensity is supported by ecological conditions that are optimal for the life of whale sharks, particularly those of juvenile age. The measured water parameters significantly influence their presence.

Abstract

There has been growing consensus in fisheries management literature that fisheries can only be managed successfully with the power-sharing and partnership of fishers. The objective of this review is to focus on examining the current global literature on fisheries co-management. The review findings lead to the conclusion that various forms of fisheries co-management exist in many countries and have different organizational forms in different fishery settings. The review has identified six principles that should be applied in designing proper fisheries co-management: subsidiarity, conflict and power, property rights, representation and knowledge, community institution building and management functions.
