“…The EU, Iran and Turkey are the main producers, with the EU and Iran producing almost exclusively for domestic consumption (Adeli & Baghaei ; Kalbassi, Abdollahzadeh & Salari‐Joo ; EUMOFA ). Within the EU, trout production is located mainly in Italy, Denmark and France (FEAP , Nielsen, Asche & Nielsen ; Eurostat ). Trout farming has a long history in European countries dating back to the second half of the 19th century.…”

The promotion of Blue Growth in aquaculture requires an understanding of the economic drivers influencing the sector at farm level, but the collection of reliable and comparable data at this level is time-consuming and expensive. This study suggests an alternative strategy for qualitative sampling of freshwater trout farms in Germany, Denmark and Turkey, using a combination of existing data, group discussions and interviews with trout farmers, consultants and researchers. Nine 'typical' trout farming models are described, focusing on profitability, productivity and energy efficiency and allowing in-depth comparative economic analyses of different production systems at farm level, across regions. Our results show that

“…While the bulk of the fisheries literature supports the idea that unregulated aquaculture can cause decommonisation (Pradhan and Flaherty, 2007, Nayak and Berkes, 2011, Benessaiah and Sengupta, 2014, Galappaththi and Berkes, 2015a, only a handful of studies suggests that there can be positive outcomes with large-scale aquaculture acknowledging their direct contribution to national economy (Nielsen et al, 2016). There are no straightforward "yes" or "no" answers to these assertions.…”

Much coastal fisheries literature supports the idea that shrimp aquaculture has the potential to cause considerable social and environmental destruction. The aim of the paper is to highlight the two faces of shrimp aquaculture as a wicked driver, emphasizing its potential role in activating systematic conversion of lagoon -based fisheries commons to non-commons and vice versa. We use the cases of aquacultureled privatisation in Chilika Lagoon, located in the Bay of Bengal area of India, and collective action surrounding shrimp aquaculture in Northwestern Sri Lanka. For both studies, data are collected through mixed research methods, including semi-directive interviews, focus group discussions, and participant observations. Our analysis shows clear evidence that shrimp aquaculture can potentially contribute to either making commons or losing commons depending on the context and influences of multi-level drivers. Aquaculture-led factors contributing to the process of losing commons in Chilika are: large-scale, individually owned aquaculture operations; encroachment of customary fishery commons; loss of commons rights (access and entitlements); breakdown of commons institutions; policy changes; caste politics and resource conflicts; ecological disturbances; change in fishing practices. In Sri Lanka, aquaculture related factors contributing to making commons are: coordinating discharge; built-in incentive for stewardship; multi-level commons institutions; collective decision-making; bottom-up management approach; mixed commons regime; and small-scale operations.

“…(Economies of scale is the cost advantage that arises with increased farm size, i.e., reduction in per-unit cost of a product.) The growth of a sector and increases in productivity are driven by increasing farm sizes induced by scale economies [16][17][18][19]. In general, labour-saving, capital-intensive, mechanized, standardized technologies benefit from larger scale operations [16][17][18]20].…”

“…Several studies argue that there is a relationship between its structure, which is able to profit from economies of scale, and the massive growth of the sector [17,21,26]. On the other hand, the stagnation of European freshwater fish culture has recently been explained by the fragmented farm structure and its inability to benefit from economies of scale [19]. The dominance of small family-owned farms particularly characterises pond-based fish farming in the EU [27].…”

Constraining Factors in Hungarian Carp Farming: An Econometric Perspective

et al. 2017

Abstract:Although carp farming had a key role in the Blue Revolution at a global level, European carp aquaculture has stagnated over the past 25 years without achieving any productivity gains. The objective of this study was to identify the factors and mechanisms constraining production and productivity growth in pond-based carp farming in Hungary, as the country is a good representative of the EU pond-based farming sector. By using data from 44 carp farms, different specifications of the Cobb-Douglas production function were parameterized to investigate the determinants of yields and to assess the extent of economies of scale. Descriptive statistics show that large differences exist in productivity between individual farms, meaning that it is hard to implement technical standards and to ensure repeatability in extensive carp farming technology. Econometric analysis demonstrates that economies of scale do not prevail in pond-based farming in Hungary, so a concentration of farms would not stimulate a growth in carp farming. This may explain the stagnation of carp aquaculture, as the only European aquaculture segments which can grow are those that can exploit economies of scale. Further analysis demonstrates that labour is an important factor of production, and a decreasing workforce may constrain the intensification process of production. On the other hand, mechanisation did not prove to be a significant contributing factor to yields, indicating that large investment in equipment has a limited role in carp farming.
