Abstract

The estuary of Bogowonto river in Kulon Progo Regency was habited by various species such as fish, shells, crabs, and snails. This research aimed to know the composition and catch rate of the fishing pot using various kinds of fodder. The method used in this research was catch identification and assessment of type, length and weight of the catch, and also the fishing pot’s effectiveness as eco-friendly fishing gear. Data analysis was conducted by measuring fish length, catch composition, and catch rate of the fishing pot. The result showed the catch composition consisted of 8 types of species which are mangrove crab (5%), freshwater crab (0.81%), pufferfish (3.38%), orange-spotted grouper fish (0.14%), green tiger prawn (0.14%), giant tiger prawn (0.41%), banana prawn (0.14%) and freshwater snail (90%). The pot with fresh fish fodder had the highest number of catch (66.08%) compare to salted fish (23.51%) and roasted coconut (10.41%) fodder. The highest catch rate of fishing pot was observed on fresh fish fodder (35.42 g/fishing pot) compare to salted fish fodder (11.19 g/fishing pot) and roasted coconut fodder (4.61 g/fishing pot). Based on the result, fresh fish is considered a more effective fodder compared to salted fish and roasted coconut.

Highlights

South coastal area of Yogyakarta region has an extensive estuary waters area, one of them is the estuary area of Bogowonto river which located in Kulon Progo Regency
The effectiveness of catching tools is considered passively, for example, fishing pot which is influenced by target species, habitat, fishing pot size, and the characteristics of the fishing pot [7]
Different fodders were tested as treatments to assess their influence towards catch composition and catch rate of fishing pot in Bogowonto River estuary in Kulon Progo Regency

Summary

Introduction

South coastal area of Yogyakarta region has an extensive estuary waters area, one of them is the estuary area of Bogowonto river which located in Kulon Progo Regency. This sea is a habitat of various aquatic organisms, such as fish, shells, crabs, and snails [3]. The effectiveness of catching tools is considered passively, for example, fishing pot which is influenced by target species, habitat, fishing pot size, and the characteristics of the fishing pot [7].
