Birds, mammals, and fish eat Atlantic Herring. For the first time, fisheries managers in New England are explicitly considering these, and other, predators when setting harvest control rules for the Atlantic Herring fishery. Based on single-species biological reference points, the herring stock is currently well above MSY levels. However, management...
The landing obligation in Europe has been in place since January 1st 2015. Experiences gained so far point out that a number of institutional initiatives have been launched, but in practice little has changed regarding discard reduction and use of discards ashore. In parallel, the wide-ranging EU research project H2020...
Conservation impacts on protected sea turtles and marine mammals are a longstanding concern in U.S. swordfish fisheries, including the Hawaii shallow-set longline (SSLL) fishery and the west coast drift-gillnet (DGN) fishery. Observer records for these fisheries document a history of rare-event interactions with large cetaceans and endangered sea turtles. Since...
Complex social–ecological systems such as small-scale fisheries require the inclusion of human dimensions in fisheries management and planning for simultaneously preserving human health and habitat health. However, linkages between ecological, social, political and economic subsystems have been largely ignored in conventional fisheries management, in Nigeria in particular. Hence, the weak...

The study contains a cost benefit analysis of the aquaculture development component of the Fish Farming Enterprise Productivity Program (FFEPP) undertaken for Meru County in Kenya. It focuses on the implementation of the FFEPP undertaken from 2009 up to 2013 and evaluates its benefits and costs against the opportunity cost...
Feedbacks between the ecosystem and the economy are important to consider when measuring impacts from a disturbance but are often missed in representations of the economy and the food web. Moreover, regional general equilibrium models often focus on how humans respond to ecological changes and do not consider that in...
Pelagic fish stocks are subject to fluctuations that are driven by climate change, overfishing and changes in market conditions. The fluctuating nature of pelagic fisheries creates uncertainties in fishers’ income, thereby adversely affecting their livelihoods. The aim of this contribution is to reduce the risk and vulnerability fishers face by...
The Florida reef ecosystem is a highly valuable resource managed by multiple federal and state agencies with many stakeholders. Over half of the $75 million annual dockside value of finfish landings in Florida is comprised of snappers and groupers, but this resource is threatened by overfishing. Current management strategies include...
Situation: UK scallop fishing is input measures, with effort limits applied to >15m vessels only. There are no output limits. Industry members noted a decline in profits, and suggested that the effort regime was to blame. Government asked for evidence to support the claim and asked Seafish for economic analysis...
The assessment of data-limited fish stocks is crucial for the sustainable management of marine living resources. Dependent on the scope and type of available data, a range of assessment methods are available, such as catch-only, length-based, or catch and survey-based methods. However, these methods suffer from several shortcomings, such as...
Indonesian tuna fisheries are complex due to variation in the scale of fleet in the fisheries, their multi-species nature and problems with data collection. Moreover, like many developing-country fisheries, their management needs to take into account many other goals besides rents maximization, such as the distribution of rents and the...
Ecolabelling has become an essential component of the global sustainable seafood trade. The MSC is currently the world leader in certification and ecolabelling programs for wild capture fisheries. While the environmental benefits of certification have been widely recognised, its economic benefits are often anecdotal or unknown. The South African hake...
We present the results of integrating the fisheries sector into an existing computable partial-equilibrium global model of agriculture, livestock, bioenergy, forestry, and land use. The model is constructed by reconciling publicly available global datasets from the FAO as well as the literature. The model of the fish sector represents capture...
Socio-economic analysis of seafood production is important for the conservation of aquatic ecosystems and the management of fisheries and aquaculture activities. Understanding how the livelihoods of people, dependent on the exploitation of aquatic resources, are affected by various changes is essential for decision making. The two main seafood production sectors,...
In this article I analyse a community-based small scale fisheries management (now becoming a co-management arrangement) for Mbenji Island located in the central part of Lake Malawi through the lenses of the concept of power. The analysis is at the local level where majority of the important actors operate. The...
Almost all recent empirical literatures that study the subjective wellbeing of fishers lack of relevant control as they are only based on surveys among fishers. Therefore, they cannot really answer whether being a fisher generate higher or lower life satisfaction, after controlling for other aspects of life. This study is...
Historically, cod fishing along the coast of northern Norway has been about fishing as much as possible with the least possible resource effort. This traditional logic is rooted in biology (cod’s migration pattern), meteorology (weather conditions) and traditional capture technology (small and not as seaworthy boats). The logic is further...
Nigeria’s domestic supply of fishery products falls short of the demand; however, there is a growing aquaculture industry that has come to the rescue in filling the gap between supply and demand. Most of the aquaculture fish farmers are prone to the risk of climate change, since weather and extreme...
Fishers exploit populations that are heterogeneously distributed in space and time without full knowledge of species distributions and with fishing gear that is not fully selective. The ability to change catch composition is limited by species mix at a particular location and time and the capture characteristics of the fishing...
