This study employs a contingent valuation survey to elicit willingness-to-pay (WTP) from Canadian recreational anglers to fish on their preferred watersheds if managers of these watersheds choose to adopt novel environmental DNA (eDNA) toolkits. The survey gathered responses from 999 Canadian...

Fish is one of the main consumable foods in Bangladesh. Fish are found naturally in river, beel, haor, pond, and baor. It is also cultivated commercially in many ways including Biofloc culture system. In this study two types of Biofloc cultivated fishes (n=10), water (n=6), and commercial...

I model the ocean as an array of lines set within a two-dimensional frame, and show how the Exclusive Economic Zone emerged as an equilibrium in customary international law. I find that custom codifies the efficient Nash equilibrium of enclosure for nearshore fisheries. For highly migratory and...

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...

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...

Can policy sustainably manage economically valuable biological resources? We find evidence it can, with the use of science-based decision rules. In 1996, with United States fish populations in decline, Congress overhauled fishing laws with scientific thresholds for rebuilding overfished stocks....

Climate change is anticipated to have long-term and pervasive effects on marine ecosystems, with cascading consequences to many ocean-reliant sectors. For the marine fisheries sector, these impacts can be further influenced by future socio-economic and political factors. Hence, raises the need...

This paper offers an overview toward assessing the implementation of the Agriculture and Fisheries Modernization Act (AFMA) or Republic Act 8435, the country's landmark legislation on the sustainable and equitable development of its agriculture and fisheries. The study presents a Theory of...

This paper aims to verify the effect of Official Development Assistance (ODA) on employment in Africa, considering sectoral employment and sub-regional groupings. The data is collected for 37 African countries between the 1996 to 2019 periods. The methodology involves the fixed effect, random...

Baumkurrennetze werden bauartbedingt sehr nahe am Meeresboden geschleppt. Um das Durchscheuern der Unterblätter dieser Netze am Meeresboden zu verringern, werden dort häufig Matten aus Kardeelen von Polyethylenseilen angebracht. Diese Tauwerks-Kardeele sind als 'Dolly Ropes' bekannt. Ein...

Transforming Philippine agriculture and fisheries (AF) into a dynamic, high-growth sector is essential to poverty reduction, food security, and inclusive economic prosperity. However, unsustainable AF practices have impacts on the environment and climate, and at the same time, ecosystem...

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...

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...

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...

Innovation and intangible asset (IA) management have not received adequate attention amongst labour- and capital-intensive sectors. This study investigates the effect of IAs on firms' performance and the internal and external determinants of firms' IA development amongst small- and medium-sized...

We study optimal harvesting of a renewable resource with stochastic dynamics. To focus on the effect of risk aversion, we consider a resource user who is indifferent with respect to intertemporal variability. We find that a constant escapement strategy is optimal, i.e. the stock after harvesting...

This study uses annual data of The Enterprise Survey and Provincial Competitiveness Index to analyze determinants of TFP of the fisheries sector and fishery firms in 28 coastal provinces of Vietnam. The paper evaluated the effects of different institutional variables on TFP at the firm level. In...

The aim of this paper is twofold. The first aim is to describe the geography and the Industrial structure of the Italian Fishing fleet. The second aim is to analyze their evolution during the period 2004-2013. The Italian fishery is one the most important of the Europe, and or the Mediterranean....

Bigeye tuna in the Western and Central Pacific Ocean were perceived as overfished for nearly 20 years, in large part due to incidental catch in the much larger skipjack tuna fishery. Efforts to halt the overfishing of bigeye stalled due to disagreements over the distribution of costs and...

Significant economic growth in marine fishing is thought to have the prospective outpace the development rate of global economy, increasing the production of greenhouse gas emissions as by-products increase. China, the largest emitter, intends to decouple marine capture fisheries from greenhouse...

The increasing consumption of seafood products raises concerns over the sustainability of marine ecosystems. We examine the role of consumer preferences on seafood demand and consequently on the sustainability of fisheries. Our analysis relies on a bio-economic model combining a demand derived...

Coral reefs, known as "the tropical forests of the ocean," have been increasingly subject to the phenomenon of anthropogenic economic pressures with sizeable negative consequences on marine biodiversity. We explore the growth process of coral reef-rich countries with the objective of evaluating...

Fishery managers face an ongoing challenge in managing commercial fisheries in a way which enables the short-term delivery of economic benefits to commercial fishers while also ensuring those benefits do not compromise the ability of fish stocks to deliver benefits into the future. This...
