Globally, climate change is inducing range shifts and expansions for numerous species. For commercially exploited species, such as those in directed fisheries, this can cause issues with management jurisdictions the species shift expand into areas at levels previously unseen. The black sea bass ( Centropristis striata) fishery has rapidly expanded northern Atlantic. Over past decade commercial ...

Human–wildlife conflict in African aquaculture and fisheries is poorly understood. We investigated this through a questionnaire aimed at owners managers of fly-fishing properties South Africa. While perceptions losses varied, all respondents reported to predators. Resulting mitigation measures, including lethal control, were employed mostly against cormorants (Phalacrocorax spp.) otters (Aonyx ...

In the recent years, resource depletion of inshore and coastal fisheries has seriously impacted Taiwan. Local fishing communities’ economic profits in these fisheries have declined and resulted in lower earned incomes for the fishermen. These phenomena have lead many scholars, government agencies and fishing communities to evaluate the optimal number of operating vessels in these fisheries. Thi...

Fisheries models are generally built to assess the dynamics of a resource with a given fishing mortality which level can be decided by some “decision maker” and/or which can be an observed process, e.g. times series proportional to some observed values of fishing effort. In these cases, the resource dynamics is represented “conditionally to” fishing mortality. This mortality must be therefore p...

Illegal, unreported, and unregulated (IUU) fishing is a major concern in fisheries management around the world. Several measures have been taken to address the problem. In Lake Victoria, the alleviation of IUU fishing is implemented through the Regional Plan of Action (RPOA-IUU), which restricts use of certain fishing gear, as well as prohibits fishing in closed areas and during closed seasons....
