User rights in fisheries refer to the rights of fishers to harvest from fish resources. In terms of exclusivity, security, duration and transferability these rights can be strong or they can be weak. For this a definition of and a measure of the strength of user rights is needed. We refer to...

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...

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...

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...

In this paper, we identify the main fishing grounds and track the response of fishing vessels' activity to tropical cyclones (TCs) in the Philippines' Exclusive Economic Zone during 2012. We use satellite imagery from the National Oceanic and Atmospheric Administration to locate fishing vessels...

This paper analyzes the current status of fisheries and aquaculture in Southeast Asia and international trade. Analysis concludes that a policy of sustainable management for both capture fisheries and aquaculture is of greatest importance, but such a policy has been neither planned nor...

Catastrophic risk is currently a hotly debated topic. This paper contributes to this debate by showing two results. First it shown that the value function in dynamic optimization can have an infinite derivative at some point even if the model specification has functional forms that are finite...

Decisions involving risk are usually taken in the presence of other insurable or non-insurable risks, the latter type called background risk. We examine how changing background risk influences risk-taking based on panel data with monthly observations from Senegalese fishermen. Fishing income is...

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...
