Abstract

The utilization of the resources of shrimp penaeid in the eastern part of the archipelagic waters Aru and surrounding sub-region III, to estimate the abundance of shrimp by using the swept area method. The aim of research to determine the composition of species caught by shrimp trawlers using a double rig, Comparative production of penaeid shrimp catch in 2014 and in 2012. Potential sustainable and penaeid shrimp with Swept area method. Results Composition Penaeid Shrimp Catch in archipelagic waters Aru and surrounding sub-region (III). There are 9 types of penaeid shrimp with the amount of catches of 17 988 kg and is the most dominant type of Green Tiger Prawn (Penaeus semisulcatus), while the lowest amount was kind Banana Prawn (Penaeus merguensis). The results of a comparative test with Chi Square (?2) turns Ho rejected and Ha accepted, wherein ?2 count 7.40 is greater than ?2 tables 0.05 (3.84) and ?2 tables 0.01 (6.63), this means that there are differences in yield catches in 2012 And in 2014 was very significant. There is a decline in production is very significant from 2012 until 2014. The potential outcome in the waters of the sub region Aru Islands and surrounding waters -III which covers 13,000 km2, where willingness stock (B) 579.58 tons, sustainable potential (MSY) amounted to 576.58 tons / year while the Total Allowable Catch (TAC) amounted to 463.67 tons / year.

Abstract

This study aims to analyze seagrass community structure in North Salawati District, Raja Ampat. The scope of research is limited to identification of seagrass biodiversity, analyzing the overrune level of seagrass type covering the area, analyzing the densities types of seagrass important value index frequencies, water parameters and seagrass area. Research method was purposive sampling by using transects with dimensions of 1 x 1 meter with a total of seven stations along 100 meters of seagrass area. The acquired data was analyzed by using analysis of closure type, density type, frequency type, and important value index. Results of biodiversity identification showed that there are two families of seagrass,      Eight species of seagrass covering the area. The overrune of seagrass covering the area in both stations is very high. The area of coverage in the both areas is above 60% (> 60%), which classified as "healthy". The density of the species in both stations is very high which classified as medium dense. Temperature, pH, DO, salinity and turbidity are in the optimum level which classified as "good". The area which overrune by Seagrass in the waters of northern Salawati District is amounted to 5.7 km2.
