Abstract

The aim of research is analyze of technical arrest and composition of the catch of fishermen using trawl hela in waters the northern coast of Tarakan.  This research used a descriptive exploratory. Retrieving data using purposive sampling station by 10%. The results research of the technical fisheries trawl of hela in Waters Juata ; Ship category is 47% ; while the smallest 12%.  Cargo capacity (GT) most dominating 3 GT 47%, while the smallest 6% : fishermen in the value of the engine unit 2 of 59%. Duration setting, towing, and hauling every fisherman, but the most dominating of any duration : set a duration of 20 minutes as much as 47% : 5 hours towing as much as 53% ; Transporting a duration of 30 minutes, as much as 41%. The results of the study the total number of catches that all fishermen ; Main catch capturing 91%, while the catch by capturing 6%; Dispose of catches at 3% ; The main catches are playing the highest catch of fishermen as much as 430 kg ; Catches up with the catch at the dominance is Penaeus esculentus by 30% ; Discard catch was dominated is Prapenaepsis sculptilis by 30%.Keywords: trawl hela; technical arrest; catch composition; Tarakan

Abstract

Mangrove leaf litter production is essential matter for organic recycling of productivity and baseline matter for living of mangrove organisms. Mangrove forest in Conservation Area for Mangrove and Bekantan (KKMB) Tarakan is one of Mangrove forest area which is not only for recreation but also ecological function of mangrove living organism’s productivity. The aim of this research was to know the rate of mangrove leaf litter production and Nitrogen organic matter contribution in KKMB Tarakan. This research was conducted from October 2015 to January 2016. The average of mangrove leaf litter productivity were Avicennia alba 3.31 g/m2/day, Rhizopora apiculata 4.65 g/m2/day, Bruguiera parviflora 3.02 g/m2/day and Sonneratia alba 6.20 g/m2/day. The contribution of Nitrogen organic matter from mangrove leaf litter showed that were Avicennia alba 0.0987 g/m2/day, Rhizopora apiculata 0.0755 g/m2/day, Bruguiera parviflora 0.0977 g/m2/day and Sonneratia alba 0.3722 g/m2/day.Key words: litter productivity, litter decomposition, Nitrogen, KKMB
