Figure 1. Production of tuna catch.

Figure. 1 showed that the catch of tuna caught in Majene waters
landed at the fish auction is a type of yellowfin tuna or baby tuna with
production results in units (kilograms). In the first quarter, the
production of tuna catches was 83,451 kg. During the second quarter
of the production of tuna catches, there was an increase in production
of 91,441 kg. The third quarter of the production of the catch
decreased by 86,558 kg, which was caused by several factors
including seasonal factors, weather and sea water temperature. In the
fourth quarter the production of tuna catches increased again as much
as 86,021 kg. The increase and decrease in catches are caused by
several factors such as climate change, seasons and several other
factors that cause the production of tuna catches to experience
fluctuations in catches.
