Abstract

Kranji waters have potential fishing grounds for the development of large marine fisheries. Kranji fishermen often face obstacles in their fishing efforts due to a lack of information about the season and potential fishing areas. The oceanographic factor of the waters can be one of the clues to determine a good catch. The purpose of this study was to determining the condition of the oceanographic parameters of the fishing area, determine the catch rate and determine the correlation of oceanographic parameters to the catch of ring trawlers. The data used in this study were temperature, salinity, depth, current velocity and catch for 10 fishing trips. Oceanographic parameters in the Kranji fishing area for 10 fishing trips were as follows: temperature ranged from 29.9- 31.8°C, water salinity ranged from 29-31.1‰, water depth ranges from 50-70 m and the current velocity ranges from 0.09 to 0.34 m/s. The variability of ring trawl production during 10 times of capture found 5 species caught. The variability and composition of purse seine catches were as follows: Tongkol Walang with a percentage of 54.42%, Tongkol Lorek with a percentage of 38.13%, belo with a percentage of 6.37%, juwi with a percentage of 0.53%, and the lowest. the percentage is bagong by 0.52%. The correlation of oceanographic parameters with purse seine catches is as follows: Current velocity has the highest correlation value with a correlation coefficient of 0.814. The temperature has a strong category value with a correlation coefficient of 0.756. Salinity has a negative correlation value with a value of -0.658. Depth has a strong category value with a correlation coefficient value of 0.657.

Abstract

Fisheries productivity plays an important role in national development. The potential of fisheries in Indonesia is quite large so that many coastal communities depend on their lives from fishing activities. East Java province has a fishery area that is quite potential with the availability of considerable human resources, one of them is Lamongan. This research was conducted in Fish Auction Site (Tempat Pelelangan Ikan, TPI) Kranji, Lamongan. The purpose of this study is to find out the productivity value of purse seine fisheries in TPI Kranji based on the size of the ship and the fishing trip. This research was conducted by survey method to know the condition of purse seine fishery in the field directly. Purse seine fishing vessels located in TPI Kranji in 2020 as many as 32 ships that have gross tonnage (GT) of 9 to 24 GT. The dominant catches are Longtail Tuna (Thunnus tonggol), Mackerel Tuna (Euthynnus affinis), Fringescale Sardinella (Sardinella fimbriata), Short Mackerel (Rastrelliger brachysoma) and Goldstripe Sardinella (Sardinella gibbosa). There are two seasons in the fishing process at TPI Kranji, the regular season (Fringescale Sardinella) and the peak season (Tuna). The highest value of productivity per trip was obtained 1.59 tons / trip / year which occurred in 2019 with 223 of fishing trips and the amount of catch production of 356.71 tons. The highest value of productivity per GT occurred in 2020, obtained 2.09 tons / GT / year, which currently has 32 purse seine vessels. The productivity per GT from year to year is increasing because the amount of production is also increasing every year.
