People have always been utilizing natural resources from the sea with various impacts on fish stocks and the marine environment. An issue that arises from humans´, specifically fishers´ interaction with the sea, is the entanglement of marine birds and mammals in fishing gears, in particular...

African aquaculture production has gradually increased over the years, but progress is still slow. Given large variations between African countries with regard to the availability of water, the macro-economic context, access to capture fisheries resources and other factors, the performance of...

Lake Victoria, globally the second-largest freshwater Lake by surface area, houses an artisanal Nile Perch Fishery that directly involves around 200K people. While the 10 whole Lake surface is potentially available to fishing activities, the fishing vessels' operational and technical...

Current regulations regarding the Nile Perch Fishery in Lake Victoria provide gear specifications for the two main gears employed, Gillnets and Longlines, by defining the minimum size available. Additionally, the legal range of catchable fish is regulated: between 50 and 84 cm. Gillnets are...

The Nile perch fishery of Lake Victoria is regulated with a slot size and with restrictions on legal gear sizes. This study provides an assessment of the effectiveness of the the slot size regulation by simulating the Nile perch fishery with a size structured population model where the size...

There are no longer plenty of fish in the sea. One-third of global fish stocks are overfished beyond biologically sustainable levels, and fishing subsidies are the primary culprit. Such subsidies incentivize overfishing, foster illegal, unreported, and unregulated (IUU) fishing and dangerously...

We uncover a hidden illegal fishing practice: the use of fishing nets with illegally small mesh size. The small mesh prevents nearly all fish of saleable size from escaping the net, but also traps a large number of fish which are too small to be sold on the market and are therefore discarded at...

This paper constructs a three-party evolutionary game model and analyzes the influence of each subject's behavior probability on the strategies of other subjects and the stability of the system. Based on field survey data, we simulate and analyze the effects of total government subsidies, the...

Despite recent improvements in the ecological status of wild-capture fisheries, a significant share (33%) of global marine stocks remains overexploited. While top-down management has been shown to work in many settings, there is growing interest in demand-side interventions, which work through...

Attempts to curb undesired behavior through regulation gets complicated when agents can adapt to circumvent enforcement. We test a model of enforcement with learning and adaptation, by auditing vendors selling illegal fish in Chile in a randomized controlled trial, and tracking them daily using...

Using marine resources in a healthy and sustainable manner is at the center of building a blue economy that will make "Sustainable Development Goal 14: Life Below Water" achievable. Fisheries and aquaculture sectors alone provide employment for and support the livelihoods of more than 200...

Whatever trade arrangement the UK decides to adopt with the EU post-Brexit, the UK government will have authority over fisheries policy. Under the EU’s Common Fisheries Policy (CFP), after many years of stock decline, there has been a recent stabilisation and even increase in stocks. However,...

This paper establishes that a targeted policy backfires because it reveals information about non-targeted units. In the world's largest fishery, the regulator attempts to reduce the harvesting of juvenile fish by temporarily closing areas where the share of juvenile catch is high. By combining...

The present study makes an analysis of fisheries sector in Haryana. For this purpose, data are collected from various issues of Statistical Abstracts of Haryana and Handbook on Fisheries Statistics. Collected data are analyzed by computing descriptive statistics, compound annual growth rate...

The closed fishing season policy for sardines in the Zamboanga Peninsula is intended to conserve the sardine species and sustain long-term operations for the sardine industry in the region. As the fishing regulation entails work suspension, it could inevitably pose serious repercussion on the...

Balancing the Tides highlights the influence of marine practices and policies in the unincorporated territory of American Sāmoa on the local indigenous group, the American fishing industry, international seafood consumption, U.S. environmental programs, as well as global ecological and native...

We analyze the effect of fisheries subsidy negotiations on financial markets and aggregate demand in developed and developing countries. We examine the plausible scenarios that are likely to emerge in the event of elimination or reduction of subsidies, and the subsequent effect on the financial...

"This book seeks to raise awareness for the conservation of marine biodiversity and sustainability of fisheries that can no longer be ignored. The impact of continuous coastal development, reclamation, destruction of corals, overfishing and increased maritime traffic places all of us on the...
