Karimunjawa merupakan gugusan pulau dilepas pantai Kabupaten Jepara yang menyimpan potensi sumberdaya perikanan yang besar. Masyarakat setempat sejak lama mendapatkan manfaat ekonomi dari sumberdaya tersebut dengan melakukan penangkapan ikan. Penelitian ini bertujuan untuk melihat karakteristik penangkapan yang dilakukan oleh masyarakat Karimunjawa. Berdasarkan hasil penelitian ini menunjukkan dominasi pemanfaatan sumberdaya ikan pelagis dan ikan karang pada wilayah ini. Alat tangkap yang paling umum digunakan adalah pancing, panah dan tonda. Sementara itu, masih terindikasi adanya penggunaan alat tangkap yang tidak ramah lingkungan khususnya potasium. Musim puncak penangkapan ikan terjadi pada saat bulan September sampai dengan Oktober dengan musim paceklik terjadi pada akhir Desember sampai dengan bulan Februari. Hal ini menunjukkan bahwa masyarakat nelayan Karimunjawa memiliki ketergantungan yang tinggi terhadap kondisi alam membuat fluktuasi hasil tangkapan sangat mempengaruhi kehidupan mereka.Title: Characteristics of Catching Fish Resources in KarimunjawaKarimunjawa is a group of islands located at Jepara district that holds great potential fishery resources. The local community has taken an economic benefit from these resources by practicing capture fisheries. This study aims to look at the characteristics of fishing carried out by the community. The results showed the dominance fishes caught are pelagic and reef fishes. Common fishing gears used are fishing rods, bows and trolling. The use of not environmental friendly fishing gear is still indicated, particularly potassium. The peak fishing season occurs during September and October with the low season occurred in late December until February. This fluctuation provide a strong influence to the community because their depedancy to the resources.

The Many

The globalization of the economy encourages massive population displacements and inevitably generates a cosmopolitization of societies. This leads to concern, misunderstanding and rejection. The most vulnerable social groups in society can perceive the population as intruders and enemies in social competition. Undoubtedly, the extreme spatial instability of fishery resources is among the many factors affecting migration dynamics. Various reasons for the mobility of fishermen are relevant around this concept. These include aspect related to traditions, to the capitalisation of activity, to technological innovations, and to innovation exchanges concerning the location of fish stocks. This article reflects on spatial increase of fishermen’s. The analyse are part of the paradigm of the sustainable management of common renewable resources, in particular fishery resources. It presents three lines of analysis: the reason for mobility; the choice of destination; and are the integration into host units.

Abstract. The purpose of this research is to analyze the role of Panglima Laot in the management of fishery resources in Sabang Island. To be able to understand the fisheries management that involves the role of the community in the form of local institutions, a series in-depth interview, observation, as well as literature were successfully carried out to local fishery community. Since this study is a combination of qualitative and quantitative method, the data collection was analysed using phenomenological approach and critical interpretation process to see the validity and reliability of the research findings.  Referring to previous research evidence, the results show that the presence of Panglima Laot has played an important role in providing information, invitation, supervision and participation in the management of fishery resources. In addition, the role of Panglima Laot in the management of fishery resources includes carrying out customs, assisting the government, resolving conflicts in the community, preventing illegal fishing, preserving the coastal environment and fighting for the living standards of fishermen is very influential both in centralization and decentralization era.  Therefore, these findings can be categorized as a useful information for any party working in field of fishery program.

Biotic or abiotic processes of seed dispersal are important for the maintenance of the diversity, and for the natural regeneration in tropical forests. Ichthyochory is one of the fundamental mechanisms for seed dispersal in flooded environments, as the “igapó” forests. A study on the ichthyochory of the igapós was conducted at Amanã Sustainable Development Reserve, in the middle Solimões river, from June 2002 to September 2004. Monthly samples of frugivorous fish were taken, with the main fishing gears used locally. Guts of 1,688 fish caught were examined. The main species were Myloplus rubripinnis (29.21%), Hemiodus immaculatus (18.96%),Colossoma macropom um (16.23%) and Mylossoma duriventre (16.05%). The diet was made of vegetables (fruits, leave and flowers), and animals (arthropods). 53.02% of all fish caught ingested fruits. The total number of intact seeds in the stomachs and intestines were 8,069 and 5,763 respectively. About 61.9% of the Brycon melanopterus (matrinchão), 46.34% of the Brycon amazonicus (mamuri) and 30.22% of M . rubripinnis (parum ) analysed had intact seeds in their guts. Seeds of Nectandra amazonum and Genipa spruceana ingested proved to be more viable than those non-ingested by fish. The high rates of frugivory, the presence of intact seeds in the guts of fish and the greater viability of ingested seeds all suggest that these animals are important seed dispersors in the “igapó” forests of Amanã Reserve.

AbstractStock overexploitation, bycatch, discards and gear impacts on the environment are outstanding issues for Mediterranean fisheries. The adoption of alternative fishing gears is an appealing solution to ensure a more sustainable exploitation of resources. We discuss the pros and cons of pots as alternative gears by reviewing their main designs, spatial distribution and target species in the Mediterranean basin. We assessed the technical factors affecting the catch efficiency of the different pot designs for four target species: spiny lobster, Palinurus elephas; Norway lobster, Nephrops norvegicus; common octopus, Octopus vulgaris and pandalid shrimps, Plesionika spp. We found that pot volume is important to catch Octopus; mesh size to catch Nephrops and Plesionika; entrance surface to catch Octopus, Nephrops and Plesionika; pot shape/colour and entrance shape/position to catch Octopus and Plesionika; and bait type to catch Octopus and Nephrops. The literature review shows that pot fisheries have several considerable advantages over conventional gears, especially in terms of discards, bycatch, seabed impacts (particularly compared with bottom trawls and passive set nets), size and species selectivity, gear depredation, catch quality and gear cost, besides saving time and labour. Disadvantages hampering their wider diffusion include ghost fishing, a low catch of finfish species, the narrow range of species targeted by each pot design and the current early stage of research. These data make a clear case for using pots as alternative gears to traditional ones in the Mediterranean Sea in some areas and seasons to catch certain target species.
