Hasil Tangkapan Mini Pure Seine Di Perairan Teluk Ambon Luar Dan Selatan Pulau Ambon

A purse seine is an active fishing gear used by fishermen in Ambon Island to catch small pelagic fish that gather in high abundance, although the information is still limited. The purpose of this research is to determine the species composition and size distribution of the catch from the mini purse seine in the waters of Outer Ambon Bay (TAL) and South Ambon Island (SPA). From the results of this research, there are four types in TAL waters and two types in SPA. In TAL, the captured fish species were Decapterus sp (Scad), Selar sp (Selar), Sardinella sp (Sardine), and Rastreliger sp (Mackerel). Sardine had the highest catch percentage at 28.41%, followed by scad (25.28%), mackerel (23.27%), and selar (23.04%). In the SPA waters, only scad (Decapterus sp) and selar (Selar sp) were found, with catch percentages of 57.83% and 42.17%, respectively. The average size distribution of scad caught with the mini purse seine in TAL waters was 16.62 cm, selar (17.22 cm), sardine (13.36 cm), and mackerel (17.34 cm). In SPA waters, the average size distribution of scad was 17.59 cm, and selar (16.63 cm).

Round scad quality on mini purse seine boats, Rembang Regency, Central of Java

Mini purse seine boats in Rembang are divided into two sizes. The first one, namely mini purse seines measuring 10 - 20 Goss Tonnage (GT) (short trips) with a fishing operation duration of 3 - 7 days. The second one is mini purse seines measuring 21 - 30 GT (long trips) with a fishing operation duration of 7 - 10 days. The dominant catch on this boats is round scad, which used a cooling mechanism with ice blocks and bulking systems. This research evaluates the quality of round scad caught by mini purse seine boats (based on Indonesian National Standard/SNI 2729: 2013) and the quality of ice used in handling the fish (based on SNI 4872: 2015). The sampling technique was purposive sampling. Fish samples were carried out in the first and last hold on the short trips and long trips boats, where each handle of the fish was sampled in the upper, middle, and lower layers. Data analysis for sensory evaluation were analyzed by Kruskal Wallis statistics, while the TPC value of round scad was tested by ANOVA test. The laboratory test results obtained the sensory assessment of round scad. The value of the TPC round scad and the E. coli ice blocks are still within the limits of the Indonesian national standards, but the TPC scale of the ice block exceeds the standard limit of SNI. The Kruskal Wallis statistics results showed tha the difference in fish hold, the difference in the trip, and differences in fish hold layers had a significant effect on the sensory of scad. ANOVA test showed that differences in the fish hold and trip differences had a significant impact on the TPC of scad. In contrast, the difference in fish hold layers gave a non-significant effect on the TPC of round scad.Keywords:Quality organolepticTPcRound scadMini purse seineRembang

Adaptive Financing Pattern for Small Scale Fisheries with Case Study of Pajeko Fisheries in Bitung

he agriculture, forestry, and fisheries sectors have a share of 22.05% with 4.21% growth in North Sulawesi. The fisheries sub-sector dominates by 30%. The disbursement of banking institutions' credit for the sector increased by 35% in 2015-2017 but absorbs only 7% of total loans disbursed. The reluctance of formal financial institutions to provide credit to improve small fisheries has increased in non-formal financing. This study identifies factors influencing financing sources choice, comparison of bank and non-bank financing sources, and recommend adaptive financing patterns for small fisheries. Based on descriptive qualitative analysis of in-depth interviews with 32 respondents from 85 Pajeko fishers (mini purse seine) in the Bitung Oceanic Fishing Port (PPS), concluded that 97% of Pajeko fishers in Bitung chose non-bank to finance their operation with determinant factors of financial source: (i) easiness administration (88%), (ii) payment flexibility (78%), and (iii) collateral (69%). The result of comparison simulation shows that boat owner financing with profit sharing for three (boat, boat owner, crews) is the most profitable for the boat owner, while bank loan financing with profit sharing for two (boat owner, crews) is the most profitable for crews. Accordingly, an adaptive financing strategy development is recommended for banking institutions based on influencing factors of fisher’s choices and Pajeko fisher’s characteristics-based approach.
