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

This research examines coral reefs vulnerability which threatening its existences and functions by climate change. The ecological vulnerability in Wakatobi (Wangi-wangi, Kaledupa, Tomia, and Binongko) was assessed during Indian Ocean Dipole (IOD) event in 2016. Climate exposure was determined using sea surface temperature, chlorophyll-a concentration, and wind speed magnitude; sensitivity was determined using coral susceptibility, fish susceptibility, and macroalgae primary productivity rate; then adaptive capacity was developed by hard coral cover, coral size distribution, coral richness, fish biomass, herbivore diversity, and herbivore grazing relative to algal production. The values of Exposure, Sensitivity, and Adaptive capacity in Wakatobi were 0.93±0.02, 0.42±0.18, and 0.44±0.10, respectively. Site specific vulnerability scores ranged from 0.52 to 1.60 (mean 0.92±0.26). Binongko was the least vulnerable than other islands. Tomia was observed as the least adaptive capacity and Wangi-wangi was the most bleaching incidents. These results could help coral reefs monitoring priority during the event and then when the event is gone by focusing on the marked islands and sites. Sites that were observed as more vulnerable is urgently need a management strategy to overcome the vulnerability status in the future, such as increasing site adaptability.

Abstract

ABSTRACTTuna is an important fish commodity in Southeast Sulawesi. It valued as an export and interisland trade product as well as an important component of local fish consumption for coastal community around Southeast Sulawesi Waters (PSST). Indonesian fisheries management is currently adopting the concept of ecosystem approach to fisheries management (EAFM). EAFM implementation in Indonesia has continued by indicators establishment to assess the sustainability performance of fisheries. Catch per unit effort standard (Standard CPUE) and juvenile composition were implemented as indicators to assess resource sustainability. Data limitations are one of the issues in fisheries management at this time, however, management efforts remain to be implemented by utilizing the best available data. This study aimed to derived recent ten years coverage of standard CPUE and it trends as well as juvenile proportion in tuna fishery based on statistical data and field observation. Assessment results show that Standard CPUE in 2014 was 0,31 tons per trip and tends to increase in year coverage, while juvenile composition was 48,6%. Based on these results, the tuna fishery in Southeast Sulawesi is still sustainable. However, there is a need to have further control and monitoring, especially on a fishery that caught tuna under Lm. Management measure has to be selected carefully in line with social economic aspects of tuna fishery in this area.Keywords: EAFM, juvenile proportion, Standard CPUE, tuna-------ABSTRAKTuna merupakan komoditas perikanan penting di Sulawesi Tenggara baik sebagai produk ekspor, perdagangan antar pulau maupun pemenuhan kebutuhan lokal bagi masyarakat pesisir di perairan bagian selatan Sulawesi Tenggara (PSST). Untuk mempertahankan keberlanjutan perikanan tuna di daerah ini maka perlu adanya suatu upaya pengelolaan komprehensif yaitu pengelolaan perikanan dengan pendekatan ekosistem atau Ecosystem approach to Fisheries Management (EAFM). Implementasi EAFM di Indonesia terus dikembangkan dengan tersusunnya indikator penilaian kinerja pengelolaan. Tangkapan per Unit Upaya atau Catch per Unit Effort (CPUE) dan komposisi yuwana merupakan bagian dari indikator EAFM Indonesia khususnya dalam domain sumberdaya. Penelitian ini bertujuan untuk memperoleh nilai CPUE baku dan kecenderungannya selama sepuluh tahun terakhir, dan proporsi yuwana berdasarkan data statistik perikanan yang diintegrasikan dengan data yang diperoleh melalui pengamatan, wawancara dan pengisian kuesioner dengan pemangku kepentingan terkait. Hasil penilaian menunjukkan bahwa CPUE baku tahun 2014 adalah 0,31 ton/trip dengan kecenderungan meningkat, sedangkan komposisi yuwana adalah 48,6%. Berdasarkan nilai CPUE baku dan proporsi yuwana, maka kinerja perikanan tuna Sulawesi Tenggara masih dinilai baik. Perlu adanya upaya pengendalian dan pemantauan lebih lanjut terutama pada perikanan yang menangkap yuwana tuna. Namun demikian, pemilihan tindakan pengelolaan harus dilakukan secara hati-hati dengan memperhatikan pemenuhan kebutuhan sosial ekonomi lainnya dari perikanan tuna di daerah ini.Kata kunci: EAFM, proporsi yuwana, CPUE baku, tuna

Abstract

This study was aimed to investigate the community structure of fish juvenile, spatial distribution and similarity from both adjacent habitats of mangrove and seagrass. This study was conducted in the eastern part of Pramuka island from April to June 2015. The samples were collected by using line transect method in three observation areas that were spatially connected i.e., mangrove, transition and seagrass zones. The result of the study from three observation zones revealed that there were found 24 species of fishes from 15 families i.e., Siganidae (4 species), Apogonidae (3 species), Ger-reidae (2 species), Terapontidae (2 species), Gobiidae (2 species), Labridae (2 species), Mugilidae, Nemipteridae, Hemiramphidae, Sphyraenidae, Monacanthidae, Atherinidae, Pomacentridae, Lut-janidae, and Lethrinidae (each of them 1 species). According to community structure, the adjacent ob-servation zones did not show a significant difference in the number of species, abundance, and bio-mass. According to fish distribution, fish species in transition zone and seagrass zone were relatively similar and dominated by Gerres oblongus, Fibramia lateralis, and Siganus canaliculatus. Mean-while, in mangrove zone revealed a significant different of fish species than in transition and seagrass zones.  In mangrove zone, fish species was dominated by Gerres oblongus and Siganus guttatus.  Keywords: spatial distribution, juvenile, mangrove, seagrass, pramuka Island, Siganidae

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 of the 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.

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

ABSTRACTBiological-Fish Aggregation Devices (Bio FADs) is FADs which designed used seaweed as an attractor.  Bio FADs in this study were made using two species of seaweed i.e Eucheuma cottonii, called cottonii FADs (FC) and Gracilaria sp. called gracilaria FADs (FG).  The purpose of this study was to analyze the dynamics of Siganus sp catch around Bio FADs based on species, abundance, and ecological characteristics spatially and temporally. The research was conducted in Uloulo coastal waters of Luwu district from October 2014 to August 2015.  Fish samples were collected by using scoop net on both types of FADs which were installed in three different habitats as observation stations. The Shannon-Wienner (H') diversity index is relatively moderate in spatially and temporally. ANOSIM  shows that the abundance of fish catches between habitats is significantly different (R = 0,268; p = 0,001).  River estuary habitat has the highest abundance of catches which is about 14.77 ind/m2.  Furthermore, the abundance of catches between monsoon was significantly different (R = 0,110; p = 0,001).  The highest abundance of fish catches in the west monsoon (WM) is about  20,67 ind/m2. SIMPER analysis shows that Siganus canaliculatus is the main species based on habitat and season. The contribution of Siganus canaliculatus is quite high in seagrass habitat which is about 96.38%. Keywords: Bio-FADs, dynamics of catch, Siganus sp.ABSTRAKRumpon hidup atau Biological-Fish Aggregation Devices adalah rumpon yang didesain menggunakan rumput laut  sebagai atraktor.
