Marine spatial planning (MSP) is a process that planners can use to make decisions about different, sometimes conflicting, ocean uses. The process is intended to be participatory and to facilitate the sharing of information about multiple uses of the marine environment. In the U.S. an important component of MSP is...
The notion of individual transferable quotas (ITQs) has permeated the fisheries economics literature over the last 40 years. The most long-standing prediction about ITQs has been extensively documented, namely that transferable property rights to harvest induce changes along the extensive margin via consolidation of quota among a smaller number of...
Overfishing and the destruction of small-scale fisheries in developing countries — particularly through the use of illegal fishing gear — is a pressing issue. Policymakers and local community leaders often suggest fines and enforcement mechanisms to reduce the use of illegal fishing; however, the response of fishery participants to “bans”...
Marine mammals and sea turtles are protected from commercial fishery interactions under the U.S. Marine Mammal Protection Act and Endangered Species Act . By design, enforcing area closures is generally less problematic than gear modifications from an enforcement standpoint. Consequently, non-compliance is a greater issue with gear modification regulations. The...
In an environment of limited resources and expanded management expectations, fisheries regulators face hard decisions about how intensively to regulate different stocks. The Fishery Management Councils are required to regulate harvest of all stocks in a sustainable manner, but have discretion on how much regulatory effort to invest in individual...

Fishery scientists distinguish between recruitment overfishing (i.e. suboptimally low reproduction because the spawning stock is fished down) and growth overfishing (i.e. catching fish at an inefficiently young age). We use an age-structured bio-economic model to study how important the (endogenous) recruitment is compared to the growth of individual fish under...
Fisheries management currently claims for fisheries governance (FG), a more balanced scheme that proposes to share the power among government, civil society and economics. In Mexico and other developing countries, the lack of operational regulations has delayed its implementation. Several authors state that topological analysis is useful to identify key...
For many years, researchers have used the theory of planned behaviour (TPB) in order to suggest that human behaviour is greatly influenced by people’s preferences and attitudes, social norms, perceived behavioural control and intentions to act (Ajzen, 1991; Armitage and Conner, 2001) [1], [2]. Over the last 20 years, this...
The role of Women and their rights in Fisheries and Aquaculture Development in Africa.

with capture fisheries dwindling and human population increasing, alternative sources have become
necessary. Although practiced for many decades, East African fish farming has been funded by donors
whose main interest has been on subsistence...
We investigate the effects of incorporating a fixed input on equilibrium profits and biomass. We first set up a theoretical model with an input that is fixed in the short-run (vessel size) but that can be used with a variable input at suboptimal capacity. We use this model to get predictions for...
The paper analyzes a situation in which the fishing fleet is subject to restrictive regulation regarding the harvest of its primal target species due to biological overfishing that in turn reveals a high level of overcapacity. The goal is to model fishermen’s expectations and likely responses to the government initiated...
Production quotas can restore efficiency in industries characterized by production externalities, such as resource industries and industries with environmental regulations. However, with imperfect quota enforcement, firms may have incentives to build up excess capacity relative to their quotas. Firms with excess capacity may, in turn, have stronger incentives to violate...
Pacific sardine (Sardinops sagax) in the California Current Ecosystem (CCE) has exhibited extreme sensitivity in its abundance and distribution in the face of decadal-scale climate regime changes. Warm regimes enhance the abundance of Pacific sardine and expand its distribution. Cold regimes lessen the abundance and restrict the distribution. For instance,...

The for-hire sector plays a significant role in providing recreational fishing opportunities for Atlantic highly migratory species (HMS) such as tuna, billfish, swordfish, and sharks. Because of the high cost of equipment needed to pursue HMS, many saltwater anglers find chartering a for-hire vessel to be the only affordable alternative....
Achieving economic viability is an important goal when it comes to developing policies for sustainable fisheries management, especially for small-scale fisheries (SSF). SSF are vital for many coastal communities, however, often economically and politically marginalized. Here, we develop and estimate what we denote as ‘basic economic viability’ of SSF, using...
Human-induced changes in life-history traits have been observed for many harvested populations, with a component of those changes being attributed to an evolutionary (i.e., genetic) response. Most notably, fish stocks that experience high fishing mortality show a tendency to mature earlier and at a smaller size. Some have suggested that...
Acute hepatopancreatic necrosis disease (AHPND), initially referred to as early mortality syndrome (EMS), is an emergent bacterial disease that has resulted in substantial economic losses for the global shrimp farming industry. Its occurrence was first reported in China in 2009, rapidly spreading to Vietnam, Malaysia, Thailand, and eventually Mexico in...
Ecologists warn that the rapid evolution occurring as a result of high-intensity commercial fishing could have potentially disastrous economic and ecological effects. The evolution of economically relevant life-history traits in fish, which can occur due to the harvesting pressure from commercial fisheries, can irreversibly diminish fisheries yields and ecological services....
By 1992, the Canadian cod populations collapsed and
a moratorium on fishing was declared, which
remains in place until today. Ecologists suspect that the marine ecosystem at the Canadian east coast
has
shifted towards a new regime, where cod stocks remain at a low level while other species biomass levels,...
Individual fishing quota (IFQ) systems are typically expected to increase the profitability of a fishery and improve sustainability by ensuring catches remain within quotas. They can also have important distributional and ecological implications that result from shifts in catch and effort between different gears, regions, and habitats. In multispecies fisheries...
Small-scale fisheries are no exceptions to the requirements of staying within the biological bounds of sustainability, by purposively limiting fish harvests, and of maintaining productivity of oceans and freshwater systems, by protecting ecosystem health and habitat quality. However, while these fisheries, like all others, have the potential to pose conservation...
In 2013 a stock of sea cucumber (Isostichopus badionotus) was discovered in northern shelf of Yucatan. A survey calculated a biomass of 17,600 tons.
