SUMMARY

SUMMARY

IDENTIFICATION

SCIENTIFIC NAME(s)

Thunnus albacares

SPECIES NAME(s)

Yellowfin tuna

An assessment unit is considered to exist in the Indian Ocean by the Indian Ocean Tuna Commission (IOTC, 2014).

In Indonesia, yellowfin tuna distribution areas cover the waters of west and south of Sumatra, southern Java, Bali and Nusa Tenggara, Banda Sea and Mallucas island’s sea, Sulawesi sea and western waters of Papua. The nature as a highly migratory species resulted in the possibility of mixing fish populations, especially for the territorial waters of Indonesia that have the characteristics of archipelagic waters directly adjacent to the ocean waters. Genetic data information  of  yellowfin  tuna  obtained  can  be  relied  upon  in  resource management (Akbar and Aris 2018).  There is no difference in the structure of yellowfin tuna populations in FMA 572 and FMA 573 (LP2T 2016). The population structure of madidihang in the western and eastern Indian Ocean regions shows no significant results of subpopulation differences (Chow et al. 2000) (Nishida and Tanaka 2004)


ANALYSIS

Strengths
    • Pole and line fishing is, in many areas, a seasonal activity. The season may change zone by zone according to the target species and its migration patterns. The habitat impact of the yellowfin tuna Indian Ocean pole and line fishery has been scored as very low risk. This is because pole and line that target tuna fish on the surface and do not come in contact with bottom habitats.
