Abstract

The natural dynamics of the distribution of fish resources in marine waters are not uniform. This will have implications for optimizing the utilization of fish resources using various fishing gear in a fishing area. Fishing using millennium gillnets is generally not done by many fishermen on Ambon Island. The research aimed to determine the composition and influence of differences in millennium gillnet depth on catch results. This research method is a fishing experiment using 3 units of 3.5-inch millennium gillnets of uniform size which are set on the bottom of the water at treatment depths, namely 0-20 meters, 21-40 meters and > 40 meters. Simultaneous capture operations in the afternoon for 8 capture attempts. During the research, the catch was 364 fish weighing 209 kg. 6 types of fish were identified, namely Kuwe (Caranx sexfasciatus), yellow-tailed Lalosi (Caesio cunning), sand porter (Naso thynnoides), Samandar (Siganus sp), and grouper (Epinephelus merra), and mackerel (Scomberomorus gullatus). This type of fish is usually found swimming in open water or near the sea surface. The highest number of catches was the Kuwe fish species, 135 fish (37.09%) weighing 56.4 kg (26.99%), the lowest was the Tenggiri fish species (Scomberomorus gullatus), 5 fish (1.37%) weighing 5.1 kg (2, 44%). The highest catch was in the 21-40 m depth range, namely 162 fish and 94.7 kg, followed by more than 41 m, namely 103 fish and 57 kg, and the lowest in the 0-20 m depth range, namely 99 fish and 57.3 kg. The chance of catching fish occurs at all net-setting depths, but the highest chance occurs at 21-40 m. The results of the analysis showed that neither the overall catch nor the dominant fish species showed significant differences based on differences in depth.

Abstract

Bottom gillnet is a fishing gear which is operated in the morning, afternoon, and evening in the waters around Lebetawi Village. However, there is limited information about the specific composition of catch, especially the differences of catch between coral and seagrass areas. The aim of this study is to compare the number of catches from coral and seagrass areas and how the fish were first caught. The research was conducted for two months, from December 2023 to January 2024, in the waters of Lebetawi Village, Tual City, Southeast Maluku Regency. Data was collected from precisely observation on bottom gillnet aperated at seagrass and coral habitatss. The catches consisted of 18 species, with total 220 individuals fish and weight 34,161.18 grams. Throughout the fishing operations at both habitats, all demersal and pelagic fish were captured by way of gilled and wedged.

Abstract

This research aimed to investigate the impact of attractor materials on the species composition and presence of fish around fish houses. The study took place in Teluk Ambon Dalam, specifically in Rumah Tiga Village, Teluk Ambon Dalam District (Figure 1), over a period of 2 months from September to November 2022. The visual method was employed, involving direct observations of fish houses equipped with either raffia rope or Polypropylene Ribbon attractors. The most commonly associated fish species were Apogon moluccensis, with 172 found on raffia ropes and 153 on Polypropylene ribbons; followed by Aeoliscus strigatus, with 129 on raffia ropes and 110 on Polypropylene ribbons. The least associated species were Abudefduf lorenzi, with 15 found on raffia ropes and 14 on Polypropylene ribbons. The study concluded that the choice of attractor material did not significantly affect the composition or presence of fish

Abstract

Garfish is a small pelagic species that has long been used as a raw material for dry fish production from Maluku called balobo dried fish. Many species of Garfish have been exploited but the species Hyporhamphus quoyi has not much been informed. This study aims to understand the reproductive aspects of Garfish consisting of measuring the sex ratio, changes in the gonad maturity stages (GMS) and counting the size of the first size gonad maturity. Located at the waters of Apara village, Aru Archipelago Regency, this study was conducted using a balobo net from November to December 2023. The catches were identified, measured its fork length (FL cm) and dissected to examine its reproductive organ. The Chi-squire heterogeneity test was occupied to measure sex ratio at different sizes. GMS was accessed based on the morphology of testis and ovary. First size maturity was calculated using Spearman-Karber method. The target fish captured by the balobo net consists of the Hemirhamphus far and Hyporhamphus quoyi. The ratio of male and female Hyporhamphus quoyi is unbalanced (c2=8.36; df=1; P=0.0038) but the sex ratio based on the length distribution of fish is not significantly different ( c2=6.92; df=6; P =0.328). Changes in GMS during the observation period indicate the occurrence of spawning in November. Balobo fish reach gonad maturity at FL = 24.9cm for females and FL = 26.8cm for males. Since the optimum size of the fish Hyporhamphus quoyi caught by balobo net is 27cm, this net produced legal sized of fishes.
