Umpan Buatan Dan Pengaruhnya Terhadap Hasil Tangkapan Pancing Layang-layang Di Selat Bangka, Sulawesi Utara (the Study of Artificial Bait on the Catch of Kite Fishing in Bangka Strait, North Sulawesi)

Needlefish (Tylosurus sp.) known locally as sako is one of the economically important fisheries resources in Bangka Strait of North Sulawesi. The success kite fishing is highly dependent on the availability of small natural bait which is caught only by lift net during the dark moon phase. Therefore, it should be attempted using artificial baits to address the issue of lack of natural bait at certain times. This study aimed to determine the effect of artificial baits toward catch of kite fishing and to identify the species of needle fish caught. This research was carried out in Bangka Strait by using experimental method. Two types of baits were used, namely natural bait (rainbow sardine/Dussumieria acuta), and artificial baits such as rubber fish that widely available in the bait shop. The catch data from four units of kite fishing were analyzed using t-test. The result showed that total catch during the study were 40 needlefish es consist of Tylosurus crocodiles (39) and Tylosurus acus melanotus (1). As many as 22 needlefishes caught with natural baits and 18 caught with artificial baits. The analysis showed that the used of natural baits were not significantly different from the artificial bait. During the study needlefish could be caught at wind speeds of 4- 7 knots and operated on 11.00–14.45 Mid Indonesian Time

Impact of Fishing Activities on the Fisheries Resources and Manado Bay Aquatic Environment

Manado Bay waters have long been known as a center of artisanal fisheries activities because of the availability of abundant fisheries resources. However, continuous increase in technoligcal development and fish resources demand make natural resources exploitation tend to destruct the aquatic habitat and fish resources itself. Therefore, this study was aimed to inventory the types of fishing gears operated in Manado Bay; evaluate the possible impact on fish resources and environment; and analyze the status of fishing fisheries sustainability. This study was based on survey methods, through direct observation of fishing process and observations on the catch composition. Fisheries sustainability status was analyzed using Rapfish program. Common fishing gears used by fishermen in Manado Bay were multi hooks vertical hand line (noru), bottom hand line, trolling line, bottom long line, surface gill net, bottom gill net and traps. Fishing gears that do not have an impact on fish resources and environment is noru fishing, trolling and surface gill net, while bottom long line, bottom gill net and trap could potentially have negative impact on fish resources and physical seabed habitat. ordination sustainability status analysis of fishing fisheries in Manado Bay for each dimension is still considered as sustainable enough. Perairan Teluk Manado telah lama dikenal sebagai pusat aktivitas perikanan rakyat karena ketersediaan sumber daya ikan masih melimpah. Tetapi perkembangan teknologi dan permintaan sumber daya ikan yang terus meningkat menyebabkan pengeksploitasian sumber daya alam cenderung merusak habitat perairan dan sumber daya ikan itu sendiri.
