PENGEMBANGAN KAWASAN BUDIDAYA RUMPUT LAUT BERBASIS ANALISA KESESUAIAN LAHAN DI PERAIRAN NURUWE

The Nuruwe waters are oceanic waters with a considerable amount of fisheries resources and a potential for tourism in natural and aquaculture tourism. This research aimed to analyze the characteristics of the physical and chemical parameters as a limiting factor for the site selection of seaweed cultivation in Nuruwe waters and analyze land suitability of seaweed cultivation based on its criteria and determine the area of cultivation. A random sampling technique was applied to the data collection of marine environmental parameters. Data were analyzed using a spatial analysis with GIS techniques and carrying capacity analysis. The spatial analysis was used to determine the land suitability of seaweed cultivation based on the site selection criteria. The results showed that water quality parameters were suitable to support seaweed cultivation with the longline system. The effective area is ± 10 ha, with the number of longlines that can be placed as many as 20 units.

ANALISIS KELAYAKAN USAHA PERIKANAN PURSE SEINE BERDASARKAN WILAYAH PENANGKAPAN DI PULAU AMBON

Our research took place in several areas of Ambon Island to be able to represent fishing areas that operate around the waters of Ambon Island, including Latuhalat Village (South Ambon Island), Hitu Village (North Ambon Island), Waai Village (West Ambon Island) and Laha Village (Outside of Ambon Bay). So it is hoped that later it can provide a detailed description of the feasibility of purse seine fisheries business based on the fishing area on Ambon Island. A method of the survey to technique the sample in purposive sampling with total respondents was the owner of fisheries purse up seine 30 business unit. Analysis of the data used is the analysis of costs, revenues and business feasibility (NPV, Net B/C, Gross B/C and Paybeck Period). the results of the study can be concluded that the purse seine fishing business on Ambon Island provides quite high profits and this business is worth developing. The NPV of the business is positive, Net B/C, Gross B/C > 1 and the ability to return the investment that has been invested in the purse seine business on Ambon Island is an average time between 1.5 years to 2.7 years. Seen from the catching area, the Latuhalat location has a high Net B/C Ratio, Gross B/C Ratio and PP when compared to the other three Locations

MANFAAT EKONOMI AKTIVITAS BONGKAR MUAT KAPAL-KAPAL POLE AND LINE DI TEMPAT TAMBAT PERAHU

Boat mooring in Dusun Pelita Jaya is used as a loading and unloading place for pole and line fishing vessels even with limited facilities.

Diversity of Demersal Fish Resources in Ambon Island Waters

The waters surrounding Ambon Island is a potential fishing gound for demersal fish resources, yet information regarding species diversity is still slightly understood. This research aimed to analyze the diversity of species and size of demersal fish around Ambon Island oceans. Data was collected based on experimental fishing using fish trap at two locations, in northern and southern waters of Ambon Island. The data were collected by experimental capture using fishing gear at two locations, namely northern waters (March-April 2015) and south of Ambon Island (July-October 2016). Methods of demersal resource diversity analysis are several ecological indexes i.e. Shannon-Wiener diversity index, Pielou uniformity index, and Simpson\u27s dominance index. The result showed that 21 family and 57 species with details of 35 species in the northern waters and 32 species in the southern water. Species diversity based on Shannon-Wiener Index (H´) ranged between 1,61-3,10 while species evenness index (E) was around 0,83-0,95. The abundance of demersal fish was not dominated by any fish species, showed by the average Simpson index of dominant (D) around 0,05-0,26
