Abstract

Pengerih is one of the trapping gears used by fishermen in Meskom Village. The purpose of this study was to determine the composition of the catch of Pengerih including the type and weight of fish caught during the day and night. This research was conducted in September 2022 in Meskom Village, Bengkalis Regency. The method used in this research is the survey method. The analysis used is by calculating the level of main catch and bycatch using the formulation of Akiyama. Based on the results of the study, it was found that the catch of curler gear was 9 types with a total catch of 5.030 fish with a total weight of 51,08 kg. The dominant types of catch during the study were red shrimp (Parapenaeus longirostris) 1.272 fish weighing 10,64 kg, striped shrimp (Parapenaeopsis sculptilis) 1,158 fish weighing 9,71 kg, white shrimp (Panaeus merguiensis) 1,115 fish weighing 9,34 kg, thorn shrimp (Panulirus sp) 883 fish weighing 7,34 kg, Moustached thryssa (Engraulis mystax) 302 fish 3,84 kg. While the bycatch consisted of print shrimp (Harpiosquilla raphidea) 39 fish weighing 1,46 kg, Bombay duck (Harpodon nehereus) 75 fish weighing 5,42 kg, Panna croaker (Otolithoides microdon) 93 fish weighing 1,46 kg, Shorthead hairfin anchovy  (Setipinna breviceps) 93 fish and weighing 1.87 kg.

The results showed that the fishing gear used by fishermen at PPI Dumai were gillnet, longline, sondong, and kurau net. The high percentage of utilization of dock facilities is about 545,45% and the port pool area is 139,98%, which means that the port pool area has exceeded highly utilized, while the utilization rate of the port pool depth is 87,5%, which means that it can still be utilized more optimally by fishermen. The utilization rate of the PPI Dumai auction building facility is 72,98%, which means that the auction building has exceeded being highly utilized

Abstract

The purpose of this study was to determine the factor of the need for supplies at sea in sondong boats and gillnets and to prove how strong the relationship between these variables is. This research was conducted in January 2022 at the UPT Fisheries Port of Riau Province using the survey method. The results showed that the factors of ship size, length of time at sea, and engine power had a strong effect on the amount of fuel carried. Based on the F-test with a confidence level of 87.1%. According to the T-test, the length of time at sea has the greatest influence, while for the application of ice, the factors of length of time at sea and catch greatly affect the amount of ice in the T-test with a confidence level (coefficient of determination) of 46.7%. According to the T-test, the length of time at sea has the greatest effect on the ice supply on the sondong ship. In gill nets, boat sizes, length of time at sea, and engine power have a strong effect on the amount of fuel carried. Based on the F test with a confidence level of 91.5%. According to the T-test, the length of time at sea has the greatest effect. Whereas in the provision of ice in gill net vessels, the length of time at sea and the catch also greatly affect the amount of ice carried with a confidence level (coefficient of determination) of 88%. According to the T-test, the length of time at sea has the greatest effect on the supply of ice in gill net boats
