There are two essential landing sites for handline tuna in Indonesia: Palabuhanratu (in the Indian Ocean) and Kendari Banda Sea). This paper analyzes catches from Ocean Sea waters as main fishing ground. The catch composition of landed is more varied than Palabuhanratu. Several species commonly caught yellowfin ( Thunnus albacares ), skipjack Katsuwonus pelamis bigeye obesus ) a target species,...

Tag release and recapture data of bigeye (Thunnus obesus) and yellowfin tuna (T. albacares) from the Hawaii Tuna Tagging Project (HTTP) were analyzed with a bulk transfer model incorporating size-specific attri­ tion to infer population dynamics and transfer rates between various fishery components. For both species, the transfer rate estimates from the offshore handline fishery areas to the lo...

Whale sharks Rhincodon typus frequently appear to interact or associate with other species, which vary depending on the community structure and demographic of whale at each location globally. Here, we present species sighted around in Galapagos Archipelago reported by dive guides scientists also earlier publications. These associated include cetacean species: bottlenose dolphins Tursiops trunca...

The population of Thunnus albacares yellowfin tuna from the Scombridae family is very abundant in North Papua Waters (WPP 717). This study aims to analyze parameters dynamics based on long-weight relationship and condition factors Demta Coastal Waters, Jayapura Regency. Fish data collection uses passive active fishing methods using gill nets, handlines, long line through activities by tradition...
