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 aim of this study was to analyze the growth and maturity level of puffer fish (Tetraodon fluviatilus). This research was conducted in October-December 2017. The research site consisted of two places, namely sampling conducted in two locations of the brackish waters of Merauke Regency while the analysis and identification of growth and maturity level of the gonads was carried out in the laboratory of Department of Aquatic Resources Management, Universitas Musamus. Sampling was conducted at Lampu Satu Beach (station I) and Payum beach (station II) using descriptive methods and survey techniques. Sampling was carried out six times at each station for three months. To find out the growth and maturity level of pufferfish gonads, an analysis of growth patterns, condition factors, sex ratio and gonad maturity levels was performed. The results of the study showed that the growth of puffer fish at Station I was negative allometric while at Station two it was positive allometric. The mean value of the puffer fish condition at Station I was 0.0499 while that at Station II was 0.7062. Gonadal maturity level (TKG) at station I and II are at TKG I, at station I is 79.04% while at station II is 69.77%. Based on the results of research conducted it can be concluded that the growth patterns and TKG at Station I are better than Station II.

Abstract

Variability of pond soil variables has an important role in many bio-environmental systems includingthe pond environment. This study aims to determine the variables of pond land. Determination ofmeasurement points and soil sampling is done randomly at 67 sample points. A total of 11 soilchemical characteristics were measured in the field and analyzed in the laboratory. The resultsshowed that in general, the type of soil in the pond area was alluvial soil with non-sulfuric acid. Theaverage negative potential for pond soil redox is -102 mV. The C-organic content of pond soil variesfrom 0,51 to 2,72% with an average of 1.60%, the PO4 content in pond soil is classified as low,between 3,27 and 53,01 ppm with an average of 20,75 ppm, meanwhile, the content of toxic elementssuch as Fe and Al in the ponds is classified as low, with an average of 529,6 and 205,0 ppm

Abstract

Penelitian ini bertujuan untuk mengetahui jenis dan kelimpahan ikan demersal yang tertangkap di perairan Sungai Maro serta mengetahui keragaman dan keseragaman ikan  pada fasa bulan yang berbeda (new moon dan full moon) pada musim peralihan I. Penelitian ini dilaksanakan pada bulan April – Mei 2019 di Sungai Maro. Sebanyak 98 ekor yang tertangkap yang terbagi pada fase bulan gelap sebanyak 45 ekor dan 53 ekor diperoleh pada fase bulan terang dengan menggunakan jaring insang percobaan dari berbagai ukuran mata jaring. Dari hasil tangkapan diperoleh 14 spesies ikan dari 14 genus terkoleksi. Keanekaragaman jenis ikan demersal pada fase bulan gelap dan terang termasuk dalam kategori rendah. Tingkat keseragaman jenis pada fase bulan gelap termasuk dalam kategori tidak merata, pada fase bulan terang termasuk kategori kurang seragam. Hasil CCA menunjukkan parameter fisik-kimia perairan  berpengaruh terhadap sebaran ikan demersal pada stasiun dan fase bulan yang berbeda.

Abstract

The Bian River, the estuary, to the coast, have very high fishery potential. Residents around the river use the Bian River as a source of livelihood and also as a means of transportation that connects one area to another. The purpose of this study was to determine species diversity, the quality of environmental parameters so as to determine environmental health conditions around the Bian River based on the Seawater Quality Standard for marine biota in PP Decree No. 22 of 2021. The results showed that during 2 months of observation, 25 species were found from three stations. Observations, where the most caught species were Metapeneus monoceros and the least species found, were Paraplotosu salbilabris, Paraplagus iabilineata, Gerresoyena, Paraplagus iabilineata. Leviprora inops, Plesio batisdaviesi, Himantura uarnak. The results of water quality measurements of temperature, salinity, dissolved oxygen (DO), and pH still support the presence of marine biota and have not been polluted in a stable category.
