Abstract

The use of flashing LED lights on squid fishing rods to catch squids is still used by fishermen without concerning the lunar phase due to a lack of knowledge about the influence of the lunar phase on the squid catch. This study was conducted to 1. determine the effect of the lunar phase on the catch of squid using fishing rods, 2. compare the number of catches obtained using blue and white LED flashing lights. This experimental study was conducted using a Randomized Block Design (RBD). Data regarding squid catches (per squid) using blue and white LED lights were collected in 4 lunar phases. Data were then analyzed using variance analysis (ANOVA). Results showed that the lunar phase significantly affected the squid catching using fishing rods at a significance level of 0.05 (5%). Catches were significantly different in the new moon, first quarter, full moon, and third quarter phases. A higher number of catches was obtained in the third quarter phase compared to other phases. ANOVA test indicated a strong significant effect of the use of LED on the catch at a significant level of 0.05 (5%). The use of flashing blue LED resulted in a higher number of squid catches than white LED since squids were more attracted by blue light than white light.

Abstract

Soma landra is classified as drift gillnet which rectangular shaped and it equipped with  floats, head rope, buoy rope, towing rope and sign buoy. In operation, it is installed in a position to cut the current direction with the intention of blocking the fish motion. The influence of moon phase is one of the factors that is closely related to fish behavior, where one of them is interested in light. Besides the brightness of the moonlight can be affected to the efficiency of capture. Therefore, the aims of this study were determined the effect of moon phase on catches and determined the catches at each moon phase. Randomized Block Design (RBD) was used in this study. The analyzed indicated that difference or reject Ho, means there are differences in catches in each moon phase. The species of fish caught is flying fish in the local language known as Marluga (Cypsilirusolegoleptis) as a target fishes with a total catch of 364.On the full moon as many as 106 (29.12%), the final perennial of 57 (15.66%), the dark moon of 79 (21.70%) and the initial peraniage of 122 fishes (33.52%).

Abstract

This study aims to determine the distribution of caught fish in "soma tono" and the types of fish caught and how the fish are caught. Soma Tono is classified in gillnets that are rectangular in shape and equipped with buoys, upper ropes, lower ropes, weights and sign buoys. Operation of soma tono fishing gear consists of preparation, net lowering (setting), soaking (soaking) and lifting the net (hauling). The principle of soma tono fishing gear (gillnet) is to wait for fish to be entangled in the body of the net. The method used is a descriptive method, namely managing data obtained when making observations, interviews and documentation. The dominance of fish obtained by bounced fish, the type of fish obtained is the dominance of demersal fish or bottom fish, namely jackfruit seed fish (Upeneus molluccensin), lencam fish (Letrinus lencan), snapper fish (Lutjanus campechanus), lolosi fish (Caesio chrysozona), kuwe fish (Caranx ignobilis), grouper (Epinephelus longispinis), curisi fish (Nemipterus nemaptohorus), sako fish (Tylosurus crocodilus), parrotfish (Scarus rivulatus Valenciennes), puffer fish (Tetraodontidae), sardines (Amblygaster sirm),  baronang fish (Siganus) and sea eels (Muraenidae).  The results obtained four phases of the moon, namely the 1st  quarter moon phase (101.5 kg), the new moon phase (168.7 kg), 2nd quarter moon phase (89 kg) and the full moon  phase (63kg).

Abstract

The aims of this study to analyze the differences the catch of the “noru” fishing gear using nipple rubber and silk fibre lures, as well as to identify the catches  obtained. Small pelagic fish are organisms that live in the open sea, separated from the bottom of the water and towards the surface layer. These fish generally like to be in groups, both with their groups and with other types of fish. Also have positive phototaxis (attracted to light) and are attracted to floating objects. Bait is an important factor in increasing the effectiveness of catching small pelagic fish using “noru” fishing gear or hand lines. The interest of artifial bait in this fishing gear has several criteria, including: the shape of the bait must be similar to shape of food, easy visible because of the color and the bait looks alive when the gear is operated. The results of the study showed that noru (hand line) to used nipple rubber lures gave more catches compared to using silk fibre lures. From the catch, there were 4 species of fish caught using nipple rubber lures, namely yellowstrip scad, bigeye scad, trevally and Indian mackerel while using silk fiber lures 2 species of fish, namely  yellowstrip scad and bigeye scad.

Abstract

Pancing adalah suatu alat penangkap ikan yang terdiri dari mata pancing dan tali atau tanpa umpan dengan memancing ikan target sehingga tertangkap pada mata pancing, salah satu jenis alat tangkap yang digunakan oleh nelayan untuk memancing yaitu pancing ulur (hand line). Penelitian ini bertujuan untuk mengetahui komposisi hasil tangkapan dengan pancing dasar sesuai jenis umpan yang digunakan dan membandingkan jenis umpan terbaik dari ketiga umpan. Penelitian ini dikerjakan dengan metode eksperimental, di perairan Batu Kapal Kota Bitung Provinsi Sulawesi Utara. Pengumpulan data dilakukan dengan cara mengoperasikan 3 unit pancing dasar dengan menggunakan umpan ikan malalugis,cumi dan udang yang terdiri 3 orang. Jenis-jenis ikan yang tertangkap selama pengoperasian pancing dasar terdiri dari 10 spesies ikan. Tetapi ikan yang tertangkap lebih dari 5 ekor hanya terdiri dari 4 jenis ikan, yaitu gaca sebanyak 11 ekor, Gutila 10 ekor, Sikuda 9 ekor, Gutila sirip merah 6 ekor. Dari hasil yang tangkapan bahwa jenis umpan yang terbaik dimulai dari umpan ikan malalugis, udang dan cumi.
