Consequences of fleet diversification in managed and unmanaged fisheries [PDF]
, 2014 Biological diversity is known to play an important role in generating and maintaining ecosystem productivity and other functions, and has consequently become a central focus of many efforts to preserve ecosystem services. Theoretical parallels suggest the diversity of fishing fleets may have a similarly important role in determining the productivity ...

Environmental and fishing effects on the dynamic of brown tiger prawn (Penaeus esculentus) in Moreton Bay (Australia) [PDF]
Fisheries Research 155 (2014) 138-148, 2013 This analysis of the variations of brown tiger prawn (Penaeus esculentus) catch in the Moreton Bay multispecies trawl fishery estimated catchability using a delay difference model. It integrated several factors responsible for variations in catchability: targeting of fishing effort, increasing fishing power and changing availability.

Fisheries Privatization and the Remaking of Fishery Systems [PDF]
Environment and Society, 2012 Th is article draws on directed ethnographic research and a review of lit- erature to explore how the commodifi cation of fi shing rights discursively and materi- ally remakes human-marine relationships across diverse regions. It traces the history of dominant economic theories that promote the privatization of fi shing access for maximizing potential ...

Experiences in Bayesian Inference in Baltic Salmon Management [PDF]
Statistical Science 2014, Vol. 29, No. 1, 42-49, 2014 We review a success story regarding Bayesian inference in fisheries management in the Baltic Sea. The management of salmon fisheries is currently based on the results of a complex Bayesian population dynamic model, and managers and stakeholders use the probabilities in their discussions.

Challenges in adaptive management of riparian and coastal ecosystems
Ecology and Society, 1997 Many case studies in adaptive-management planning for riparian ecosystems have failed to produce useful models for policy comparison or good experimental management plans for resolving key uncertainties. Modeling efforts have been plagued by difficulties

Ecology and Society, 2011 Adaptive governance can be conceptualized as distinct phases of: 1) understanding environmental change; 2) using this understanding to inform decision making; and 3) acting on decisions in a manner that sustains resilience of desirable system states ...

Hydrographic variability and biomass fluctuations of European anchovy (Engraulis encrasicolus) in the Central Mediterranean Sea: Monetary estimations and impacts on fishery from Lagrangian analysis [PDF]
arXiv, 2021 During the last decades, scientific community has been investigating both biological and hydrographic processes that affect fisheries. Such an interdisciplinary and synergic approach is nowadays giving a fundamental contribution, in particular, in connecting the dots between hydrographic phenomena and biomass variability and distribution of small ...

Square Root Laws in Structured Fisheries [PDF]
, 2020 We introduce the term net-proliferation in the context of fisheries and establish relations between the proliferation and net-proliferation that are economically and sustainably favored. The resulting square root laws are analytically derived for species following the Beverton-Holt recurrence but, we show, can also serve as reference points for other ...

Renegotiating property rights in the Florida golden crab fishery
International Journal of the Commons, 2013 The golden crab ('Chaceon fenneri') supports a small, economically healthy fishery in south Florida. Crabbers in the fishery have successfully protected themselves against larger outside fishing interests in the past, and management has been stable for ...
