ABSTRACT The success of baited hook and line fishing gear is determined by the activity of fish in terms of finding and catching food. Adding shrimp extract on bait may increase the fishing power of the bait; but this kind of scientific information, particularly on the bottom hand line is not widely available. This study aimed to determine the effect of shrimp extracts on demersal fish catch in the surrounding fishing ground and to identify the species caught by the bottom hand line. This research was conducted in coastal waters Tateli Weru Village, District of Mandolang, Minahasa in October 2015 which was based on an experimental method. Six units of bottom hand line was operated, where three units using bait of scad mackerel marinated in shrimp extract, and three other units using plain bait of scad mackerel; and the data were analyzed using t-test. Total catches was 60 fish; 38 fish caught by bait with shrimp extract, and 22 fish caught by bait without shrimp extract. The results showed that use of bait with shrimp extract give more catches.

ABSTRACT Fishery potential in Manado Bay, especially capture fisheries is quite large; but fishing activities that carried out by fishermen are still relatively in small scale; which is dominated by various types of hook and line, and small purse seine. Trolling is a traditional fishing gear that commonly used by fishermen in Manado Bay to catch pelagic fish species with artificial bait. This research aimed to study the effect of artificial bait color on the catch of trolling; and to identify the fish species. This research was conducted in January 2015 based on the experimental method. Two types of artificial bait colors were used, i.e. blue and pink; artificial bait was made of silk fibers. Catch data collected using small boats Pelang types, with 2 units of trolling line; operated during daylight from the morning (06:00 Wita) until the afternoon (18:00 Wita), data recorded every 2 hours for two days; and the data were analyzed using t-test. The catch of trolling line consists of Auxis thazard (0.2 kg), Selar sp (0.1 kg) and Katsuwonus pelamis (1.54 kg). Results of the analysis showed that the use of blue artificial bait on trolling caught more fish than that of pink artificial bait.
