Although aquaculture is the food-production industry that has grown the most in recent years, its companies inherently face more variability in their results than companies from other industries This can be explained by the increasing complexity in their decision-making processes, due to the large number of, external and internal, influencing...
The valuation marine ecosystem services have been receiving increasing attention in scientific literature, however most of the research is focused in marketed services and does not consider the part of the total economic value. Some services like cultural services that are not direct (touristically) or indirectly marketed as part of...
Nigeria with an annual potential of 2.5 million tonnes of fish from aquaculture produced only 316,727 tonnes in 2015 out of the domestic production of 1.027 million tonnes and total fish demand of 3.25 million tonnes. The government has put in place a lot of initiatives to increase aquaculture production...
Fishing systems provide employment, income generation, poverty alleviation, and food security. Management actions have ecological, economic and social implications that must be addressed carefully. The coexistence of small-scale fisheries (SSFs) and large-scale fisheries (LSFs) increases management complexity. Game-theoretical bioeconomic models empower management decisions in such complex systems.
One pressing economic, societal and environmental issue affecting commercial fisheries is the production of undesirable outputs. In fisheries, undesirable outputs often arise because of economic or regulatory discarding of commercial species and/or the incidentally caught or ‘take’ of protected species, such as sea turtles and marine mammals. In fisheries, undesirable...
Iran is among the pioneers in the farming of rainbow trout that is mostly up to 1 kg with a production of 173,000 tonnes in 2018, principally used for domestic consumption. Farmers use labour-intensive hand feeding and counting eggs by hand. Imported trout eggs are preferred to domestic eggs as...
The estimation of production frontiers using revenue as the dependent variable is very common in fisheries research since in multi-species fisheries boats catch several species and their output must be aggregated somehow. The objective of this paper is to decompose revenue efficiency into two components, one due to quantities and...
This contribution aims to provide an economic assessment of the seabream and seabass industry in the Mediterranean, in order to describe the recent development and current situation of the economy and markets of this industry. It focuses on analyzing the economic and financial structure at different levels of aggregation (industry,...

Introduction: The issue of the economic relations between major fishing countries (EU and Asian countries) if of major concern: Overt and tacit vessel subsidies, the asymmetry in the benefits for lower income and higher income countries from fishing and fish processing, LDC EEZs account for around 11 per cent of...
