Abstract

This study aims to analyze the growth and condition factors of Snakehead fish (Channa striata Bloch, 1793) caught in the waters of the Wasur swamp, Merauke district. The research was conducted in September-November 2020 in the Wasur swamp waters. The method used is descriptive method with purposive sampling technique. The data analysis used was the long-weight relationship data to determine the growth pattern of snakehead fish and condition factors. The results of the research at the two stations in September and October showed the same growth pattern, namely negative issometric and allometric, while in November station I was allometric negative and station II was issometric. The value of the condition factor at the two stations in September, October and November ranged from 1.003 to 1.006, including in the not fat category.

Abstract

The purpose of this study was to determine the content of N (nitrogen), P (phosphorus) and potassium (K) or NPK in dry waste fish and in liquid organic fertilizer (POC) from non-target fish waste caught by fishermen. The research was conducted in September-November 2020, at the Unmus Merauke Water Resources Management Laboratory and the Unhas Chemistry Laboratory. Sample analysis includes testing the levels of Nitrogen (N), Pospat (P) and Potassium (K) found in non-target fish waste caught by fishermen in Samkai village. The results showed that the NPK analysis results in dry waste fish had levels of Nitrogen (N) 0.58%, Phospor (P) 2.86% and Potassium (K) 0.01%. The results of the analysis of liquid organic fertilizer (POC) from fish waste, while the best analysis of liquid organic fertilizer (POC) on Nitrogen (N) nutrients at P3 was 0.27%, Phospor nutrients at P3 were 1.25% and for Potassium (K) nutrients at P1 equal to 0.74%.
