In this report, the main challenges of managing orange roughy fisheries are outlined, as well as lessons learned that could be applied in the future to fisheries for this species (and others like it) which in some cases may allow for an ecologically sustainable, albeit limited, commercial fishery. The term ‘sustainable’ or ‘sustainable fishery’ in this context is defined as a fishery which meet...

There is increasing concern for the conservation of sharks among scientists, environmental conservation advocates, and the interested public, but misunderstanding among policy non-specialists about which conservation and management policies are available, and which might work best for certain situations, persists. Here we present a review of fisheries management and conservation literature rela...

Management of public resources, such as fisheries, is a complex task. Society, in general, has a number of goals that it hopes to achieve from the use of public resources. These include conservation, economic, and social objectives. However, these objectives often conflict, due to the varying opinions of the many stakeholders. It would appear that the techniques available in the field of multip...

vailing currents and use their highly developed sight to stalk prey. Female swordfish grow faster and live longer than males. They reach their maximum size (usually ~350 kg) at about 15 years of age. Male and female swordfish have different distributions depending on size. Within swordfish populations, a proportion of the fish associates with underwater features such as banks and seamounts. Suc...

The objective of this study is to describe the genetic population structure and demographic history of the endangered marine fish, Epinephelus marginatus, within Malta's Fisheries Management Zone for the purpose of localised conservation planning. Epinephelus marginatus is a long-lived, sedentary, reef-associated protogynous hermaphrodite with high commercial and recreational value that is at r...

About 85% of the Mediterranean and Black Sea stocks assessed are fished at biologically unsustainable levels (FAO, 2016). The experience of EU fisheries management is unique in its scope and ambition, in that it represents the only example of reconciling the concerns of a variety of coastal countries and eco-regions with diverse, if not divergent, interests into a Common Fisheries Policy, the C...

The potential use of functional evolutionary models and mechanistic ecological models as predictive tools in fisheries ecology is discussed. Evolution by natural selection is a force that leads to ecological adaptations of the individuals in the populations. By mechanistic modelling of the sense organs, we may model how individuals perceive their environment, and by life history theory we may p...

Executive Summary Introduction Recreational fishing represents a popular and highly valued use of marine resources, with participation by a large percentage of the U.S. population. Nonetheless, many recreational fisheries, including a number of fisheries in the Gulf of Mexico (GOM) recreational reef fish complex, show trends towards shorter seasons, smaller bag limits and more restrictive size ...

We analyze the problem of an integrated management of fisheries by using fish farming as a tool for restocking fish populations depleted by overfishing pressure. We first use a simple heuristic dynamic model, taken from a classical example of mathematical bioeconomics, in order to prove that fish restocking may be an efficient tool for sustainable fishery management in situations where excessiv...
