The potential of fish resources in the waters of the Indian Ocean in south of Java to the Nusa Tenggara amounted to 491.7 thousand tons per year which is 40.95% of them (about 201.4 thousand tons per year) is large pelagic fish such as Tunas. The coastal area of Tanjung Luar, which located, which is located in Keruak District, East Lombok, is one of the centers of small-scale tuna fisheries in West Nusa Tenggara. One of the fishing fleet which is developed at Tanjung Luar to exploit the resources of tuna is “jukung/ketinting”. The fleet has a variety of gear types. The objectives of this this study was to describe the diversity of fishing gear, fishing locations, the composition of the catch, CPUE, length distribution, length-weight relationship of neritic tuna caugh and water temperature information based on data from the observer trip report in 2014. Data was collected through observation in June, August and October 2014 at the Fish Landing Base of Tanjung Luar. Observations were carried out by following the one day of fishing activity. In a total, there were 38 trips to obtain the data. Biological aspects of the collected data covering the length and weight of the fish caught. Water temperature at the location of the data collection area is obtained by using minilogger. The Jukung (small boat) fleet in Tanjung Luar had five types of troll line and three of the was used to catch neritic tuna. Bullet tuna is the highest CPUE, followed by kawakawa and frigate tuna. Most of the bullet tuna caught were allegedly had ever spawn, whereas the little and frigate were in immature size. The bullet, little and frigate tuna were negative allometric. The average temperature of Alas Strait was 26, 1 0 C.
