Abstract:
... Fishing community social networks function as channels for transfer of fishery knowledge, resources, and business transactions that help mitigate risks and shocks associated with altered access to fishery resources. Research on such networks in Alaska is limited despite their cultural importance and community reliance on fisheries. We contribute to scholarship of fishery social networks by assessi ...

This review highlights the beneficial influence of cold-water coral habitats and Bari canyon on the abundance of the bentho-pelagic fauna and demersal fisheries along the Apulian continental margin, between the South-western Adriatic and North-western Ionian (Central Mediterranean). Because of its fisheries' value, this geographic area deserves the implementation of a new Fisheries Restricted Area ...

Abstract:
... This paper unpacks the competing narratives used by stakeholders involved in a conflict over the use of Port Phillip Bay, in the Australian state of Victoria. The ‘best available science’ (BAS) indicated that the Bay’s commercial net fishery was ‘sustainable’. And yet, both the major political parties went to a tightly contested state election with the promise to close the fishery in favour of a ‘ ...

Abstract:
... Like other fisheries models, multispecies models are subject to various sources of error. However, with regard to their use for ecosystem-based fisheries management (EBFM) between model errors are likely to be most important. As multispecies models are by definition many-dimensional, comparing them is potentially a complex task. The paper uses a simple approach. This is to calculate the Jacobian m ...

Abstract:
... The Australian Victorian Western Zone rock lobster fishery is assessed using standardised catch-per-unit-effort (CPUE). Nominal CPUE declined over 1978–2009, but this underrepresents the estimated decline in abundance, and since 2009 standardised CPUE rose notably less than nominal CPUE. This study identified vessel as a key factor that explains the discrepancy between nominal and standardised CPU ...

To ensure efficient and sustainable purse-seine fisheries, it is necessary to understand well the fishing performance of a purse seine, which can be related to many factors, such as mesh size, twine materials, leadline weight, fishing operations and the marine environment. In this study, we tested two tuna purse seine model nets with different mesh sizes to obtain the lateral and drifting distance ...

Abstract:
... The stock assessment model SAM (state-space assessment model) is an important tool for analysing fishery data and is used for abundance estimation of several different fish stocks. We demonstrate incongruous formulations in the equations that relate the catch data to fish abundance, and in the fishery and natural mortality rates. We present example results to show how these formulations introduce ...

Abstract:
... Data from the historical River Ems glass eel fisheries in the 20th Century have been used for the ICES recruitment series. Commercial catches ceased from 1980 and dropped to zero; thus, eel recruitment data are since lacking. The present study assessed the actual eel recruitment to the River Ems with regard to the local tidal conditions. Standardised measurements were performed on relative glass e ...

Abstract:
... Co-managed territorial use rights for fishers (TURFs) have shown promise for small-scale fisheries management. The territorial use rights help clarify access and ownership rights, while co-management arrangements create formal relationships between fishers and government. However, there is limited research into the governance processes that influence the interactions and complementarities of TURF ...

Abstract:
... Abundance estimates facilitate successful fisheries management. Fisheries agencies often monitor abundance through fishery independent standardized protocols generating relative measures such as catch-per-unit-effort (CPUE), where CPUE is assumed proportional to true abundance. Unfortunately, this assumption is rarely met as fish behavior and environmental conditions influence catchability and sam ...
