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.

AbstractOffshore wind farms (OWFs) act as artificial reefs, attracting high abundances of fish, which could potentially increase their local production. This study investigates the feeding ecology of fish species that abundantly occur at artificial habitats, such as OWFs, by examining the short- and the long-term dietary composition of five species: the benthopelagic Gadus morhua and Trisopterus luscus, the pelagic Scomber scombrus and Trachurus trachurus, and the benthic Myoxocephalus scorpioides. We conducted combined stomach content and stable isotope analyses to examine the short- and the time-integrated dietary composition, respectively. Our results indicated that benthopelagic and benthic species utilize artificial reefs, such as OWFs, as feeding grounds for a prolonged period, since both analyses indicated that they exploit fouling organisms occurring exclusively on artificial hard substrates. Trachurus trachurus only occasionally uses artificial reefs as oases of highly abundant resources. Scomber scombrus does not feed on fouling fauna and therefore its augmented presence in OWFs is probably related to reasons other than the enhanced food availability. The long-termed feeding preferences of benthic and benthopelagic species contribute to the hypothesis that the artificial reefs of OWFs could potentially increase the fish production in the area. However, this was not supported for the pelagic species.
