Abstract

Dengan adanya Undang-undang nomor 32 Tahun 2004 tentang Pemerintahan Daerah, Pemerintah daerah dalam hal ini pemerintah kabupaten atau pemerintah kota memiliki peranan penting dalam pengelolaan perikanan karang. Disisi lain kapasitas sebagian pemerintah kabupaten dan kota dalam pengelolaan perikanan masih relatif lemah. Sehingga banyak pemerintah kabupaten dan kota tidak melakukan kegiatan pengelolaan perikanan karang. Kota Sabang, merupakan kota terletak di ujung barat laut Pulau Sumatera, termasuk wilayah Provinsi Aceh. Berdasarkan Rencana Pembangunan Jangka Panjang Kota Sabang, bidang perikanan merupakan salah satu bidang prioritas dalam rencana tersebut. Salah satu masalah utamanya adalah kapasitas pemerintah Kota Sabang masih terbatas dalam melakukan pengelolaan perikanan khususnya perikanan karang sehingga memiliki kelemahan dalam menyusun strategi pengelolaan perikanan. Tujuan penelitian ini adalah: adanya kajian status kelembagaan pemerintah kota sabang dalam melakukan pengelolaan perikanan karang; dan adanya strategi dan rekomendasi pengelolaan perikanan karang berdasarkan status kelembagaan. Metode yang dipakai dalam studi ini adalah Institutional Development Framework (IDF) yang dikembangkan oleh Renzi (1996) dan Manulang (1999). Hasil penelitian menunjukkan secara kelembangaan, Dinas Kelautan, Perikanan dan Pertanian (DKPP), Badan Perencanaan Pembangunan Daerah (BAPPEDA), dan Badan Pengendalian Dampak Lingkungan, Kebersihan dan Pertamanan (BAPEDALKEP) berada dalam tahap pemantapan dalam melakukan pengelolaan perikanan karang.Kata kunci: kapasitas pemerintah, pengelolaan perikanan, perikanan karang

Abstract

Global fish stock has been significantly declined over the past 3 decades, especially in coastal waters. Over-exploitation of fish resources and habitat destruction has been considered playing important role in declining the fish stock. This study was conducted to restore sea cucumbers stock in Pulau Seribu. A base line study was needed to evaluate the status of seagrass ecosystems in restocking locations. The results showed there were 8 seagrass species identified in both study sites, covering 0-65% area, consisted of 20.45 ± 11.28% in Pulau Pramuka and 6.00 ± 6.56% in Pulau Kelapa Dua, respectively. Seagrass ecosystem in Pulau Pramuka indicated better condition than that in Pulau Kelapa Dua and statistically was significantly different (global R = 0.193; p < 0.001). However, to support the restocking efforts of sea cucumbers, the seagrass habitat in both locations need to be restored. Keywords: restoration habitat, sea cucumbers restocking, seagrass ecosystem status

Abstract

Today, eel resource especially seeds in Indonesia has not been used for eel culture activities. To be able to optimally utilize the seeds that led to the production of eels for consumption needs adequate cultivation technology. This study aimed to obtain performance information of survival rate, growth rate, and feed conversion ratio to support mass production of eel consumption. The experiments were performed using aquarium of (0.8 x 0.4 x 0.4) m3 and concrete tank (1.7 x 1.7 x 1) m3 with circulating water. Eel used were elver (1.2-1.5 g) and fingerlings (15-17 g). Silk worms (Tubifex) and artificial feed in the pasta form were used as feed. The results showed that the elver reared in aquarium or concrete tank with water recirculation system showed high survival rate of 78-79% and 86-96%, respectively. The specific growth rate (SGR) was good (0.6-0.8%), but the feed conversion was still high (33-21) for the elver fed with silk worms and very good (0.6-0.7) for elver fed with artificial feed. The juvenile eel reared in a concrete tank showed SR up to 85-94%, the SGR ranged from 0.8 to 1.2%, and feed conversion from 0.61 to 0.69. It can be concluded that the rearing of seed eel can be done incontainer using water recirculation system with stocking density of 3 individuals/land 1.5 kg/m3 in preparing the seed to be ready tobe cultivated outdoors. Keywords: elver, feed conversion ratio, juvenile, specific growth rate, water recirculation system

Abstract

Fishing has adirect and indirect impacton coastal and marine ecosystems. The fishing activity has been intensively conducted in the Southeast Maluku district and potentially impact the fish resources negatively. Fishermen generally catch fish using gill nets, lift net and hook line. This study aims to analyze the impact of fishing on ecosystem structure and trophic level of the catch by each fishing gear. An experimental fishing was conducted for the sampling strategy by means of fishing operations using gill net, lift net and hook line. Data were analyses for parameters of feeding habits, length-weight relationships, and trophic level of the catch. The results showed that trophic level of fish taken by lift net and gill netranged from 2.9 to 3.7 which grouped as TL3, dominated by species of omnivorous feeding habit (zooplankton). The gill net has dominantly caught the group of fish at trophic level 5 (4.0–4.5). The average total length of the dominant fish targets were D. Russeli (18.2±12.5cm), Sardinella longiceps (19.8 ± 13.3cm), S.crumenopthalmus (21.9 ± 14.2cm), Lethrinus lentjan (20.1 ± 13.3 cm) and Upeneus mulocensis (21.9 ± 14.2 cm). For the average weight ofthe main catches were D. Russeli (90 ±35 g), Sardinella longiceps (81±28g), S.crumenopthalmus (89 ± 40g), Lethrinus lentjan (92 ± 28g) and Upeneus mulocensis (90 ± 30g). The catch by lift net, gillnet and hook line indicates unbalance exploitation of the natural food chain. TL groups 3 and 5 was more dominantly exploited. It is theoretically potentially impacting the ecological balance of fish resources in these habitats. Furthermore, the lift net and gill net have greater impact on sustainability of fish resources than hook line due to both the earlier dominantly exploited unallowable catch sizes (juvenile) of the fish target. Keywords: Fishing impact, trophic level of catch, feeding habits, Southeast Maluku

Abstract

Research on fish behavior in boat lift net fisheries (bagan petepete) equipped with LED light is very important since the similar research is very limited conducted in Indonesian waters. The purpose of this study was to understand the LED light distribution and its impact on the fish behavior around the LED light.  This study was conducted in the laboratory of Simulation Workshop and Navigation, Pangkep State Polytechnique of Agricultural and fishing experiment was done in Barru District waters, Makassar Strait, South Sulawesi. The light intensity was measured by a digital lux meter and under water lux meter, while fish behavior was observed by side scan sonar color. Light intensity analyses showed that the distribution of 80 watts LED light was mostly focused with 1096 lux with an angle168°. Fishes approached the light at 5-10 m and 20-30 m water depth from all directions after all lights were turned on. Fishes in smaller groups and higher density concentrated around the light when only one lamp was turned on. After catch processing, some fishes left the lighting area and others still stayed in the lighting area. Keywords: fish behavior, LED lamp, light fishing, lift net

Abstract

To achieve sustainable fisheries management needs appropriate and validated indicators. The purpose of this study is to evaluate the ecological indicator of sustainable fisheries base on fishery statistic data. The analyses of diversity, similarity, and clusters were conducted on landing data of fisheries statistic for ten years of 1995-2005 in Kotabaru District. Result of this study indicated the variations of diversity parameters of catch in this area. Characteristic taxa of the catch in Kotabaru were family Penaeidae (shrimp), Scombridae (mackerel), Clupeidae, and Carangidae. The group of demersal fish was mostly exploited during the year 1995-2005 comparing other species. Finally, this study confirms such ecological indicator of sustainable fisheries could be developed base on landing statistic data, however a multi-indicator should be used in order to asses the state and trend of fisheries comprehensively in certain location.
