Comparative Yield Performance of Upland and Mangrove Aquacultural Farms in Selected Maritime States of Southwest, Nigeria

Creator:: Mafimisebi, T. E. and Okunmadewa, F. Y.
Abstract:: Investors in aquaculture are biased against the mangrove areas and prefer to site their farms in the upland parts of Southwest, Nigeria. This study was carried out to compare the yield performance in the two fish farm locations. The tools utilized included descriptive statistics, budgetary and cash flow analyses and...

Are Middlemen Really Exploitative? Empirical Evidence from the Sun-Dried Fish Market in Southwest, Nigeria

Creator:: Mafimisebi, T. E. and Okunmadewa, F. Y.
Abstract:: The animal protein intake in Nigeria is grossly insufficient yet the retail price of fish is rising. Market intermediaries, alleged to charge excessive and unjustifiable marketing margins (MM), are often blamed for this. This study examines this allegation using data from 225 sun-dried fish traders classified into three groups. Data...

A Feasibility Analysis of Implementing the Closed Fishing Seasons on the North-east Coastal Fisheries in Taiwan -- An Application of Fisheries Co-management

Creator:: Hao-Ting, Liu, Chuang, C. T., Lee, Y. H., and Chang, C. W.
Abstract:: The status of fisheries resources on coastal and offshore areas is getting worse in Taiwan. Thus, to establish a fishery resources management system has become the main task among stakeholders. In this study, we would like to examine the feasibility of imposing the community-based co-management system and setting closed fishing...

Inefficient Decisions, Emergencies and the Benefits of Delegated Power: Measuring Commission Power in EC Fisheries Policy-Making

Creator:: Rahming, Anne J.
Abstract:: The failure of the European Union’s Common Fisheries Policy (CFP) to develop a sustainable fishing environment for all member states is often blamed on the incompatibility of the territorial logic of national interests and the market forces of a de-territorialized European Union. Ironically, it is precisely this incompatibility that a...

A Comparative Evaluation of the Estimation of Effort-Profit Relationships in the Scottish Demersal Trawl Fishery

Creator:: Revell, B. J. and Pascoe, S.
Abstract:: Generalised linear estimation and multi-layer perception neural network modelling techniques were applied to the Scottish trawler fleet data in order to estimate which inputs have the greatest impact on boat profits and output. Both produced comparable estimates that revealed inelastic and non-linear response to vessel power and length, negative response...

A precautionary approach to aquaculture: the incorporation of risk and incertainty in the feasibility analysis of shrimp hatchery in Mexico

Creator:: Martinez-Cordero, F. J., Seijo, J. C., and Juarez, L. M.
Abstract:: Sustainable aquaculture can be achieved when risk and uncertainly are incorporated in the analysis of the activity. This paper presents a precautionary approach to the feasibility analysis of a project for a commercial hatchery, applying decision theory. Two production scenarios were assessed, continuous and periodic, the later a combination of...

Evaluation of frozen fish marketing in southwestern Nigeria

Creator:: Fagbenro, Oyedapo Adewale and Afolabi, J. A.
Abstract:: The study examined the marketing of frozen fish in southwestern Nigeria. It determined the profitability of fish marketing and investigates the market structure for fish in the study area. A multistage sampling technique was used to select 150 frozen fish marketers in the study area. Gross margin analysis and Gini-coefficient...

The Optimal Recovery of a Semelparous Fish Population with Delayed Recruitment

Creator:: Doole, Graeme J. and Alexander, Robert R.
Abstract:: Annual recruitment of the New Zealand longfin eel (Anguilla dieffenbachii) has decreased by around 75 percent since heavy levels of commercial fishing began in the early 1970s. Given the unsustainability of existing regulatory policy, a deterministic multiple-cohort bioeconomic model is developed and applied to this system to gain insight into...

Bioeconomic assessment of alternative cold-water aquaculture species: early life stages

Creator:: Dalton, Timothy J. and Waning, Kate M.
Abstract:: Despite several factors favoring the development of haddock (Melanogrammus aeglefinus) aquaculture, there is virtually no economic information on its feasibility. This paper uses bioeconomic simulation techniques to conduct an ex-ante impact assessment of the early life stages in haddock production. Using an economic engineering methodology, early life stages are modeled...

Reference Points for Vulnerable Fish Species Based on Bioeconomic Age-Structured Models: An Approach for Totoaba macdonaldi

Creator:: Rodríguez-García, Oswaldo Uriel, De Anda-Montañez, Juan Antonio, Valenzuela-Quiñonez, Fausto, Hernández-Flores, Alvaro, Salas-Márquez, Silvia, and María Da-Rocha, José
Abstract:: Management objectives of vulnerable fish species must focus on maintaining healthy population status. Hence, reference points should be constrained to ensure recruitment. We assessed bioeconomic reference points for the totoaba (Totoaba macdonaldi), an endemic fish to the Gulf of California, reaching lengths of 2 m and 25 years. Totoaba fishing...
