Recent Honduras Grads Address Tilapia Issues
our students at Escuela Agrícola Panamericana (Zamorano), the host country institution for the CRSP Honduras Project, recently completed bachelor's theses related to CRSP research. We would like to offer our congratulations.
Martínez Ayala, Jose A. 2000. Socioeconomic characterization of farmers with and without tilapia production systems in Honduras. Special project of the Agronomy Engineering Program, Zamorano, Honduras. 52 pp.
The objective of this study was to identify the social and economic conditions that characterize those small-scale farmers who have incorporated tilapia production within their aquaculture production systems. The significant statistical (P < 0.25) variables found were the size of the farm, age and marital status of the producer, source of principal income, use of land, occupation of the producer, participation in projects, and the main product of the farm. All of these variables were found to have some influence on the adoption of a tilapia production system.
Mejía, Gloria M. 2000. Study of production costs of three tilapia culture systems on small- and medium-scale farms in five departments in Honduras. Special project of the Agronomy Engineering Program, Zamorano, Honduras. 44 pp.
The objective of this study was to define the technical characteristics of three production systems–commercial, semi-commercial, and subsistence; to compare costs in order to identify differences among systems; and to determine cost structures. This study found that the technical characteristics of subsistence systems were the most variable and deficient due to the low importance of aquaculture as an on-farm economic activity. Also, cost structures were significantly different among the three systems, which is a function of the differences in production practices and level of technology employed in each system. Lastly, the highest production costs were those of subsistence enterprises, while the lowest were those of enterprises with commercial goals.
Molina, Juan C. 2000. Studies on actual and potential demand for tilapia in five secondary cities in Honduras. Special project of the Agronomy Engineering Program, Zamorano, Honduras. 59 pp.
The objective of this study was to characterize institutional and non-institutional tilapia markets used by small- and medium-scale tilapia producers in five cities in Honduras. This study found that, in all of the cities, the red tilapia was preferred and the type of presentation in highest demand was whole. The preferred characteristic of tilapia was flavor, whereas spininess and problems with availability in markets were least preferred.
Quan Barcia, Vivian L. 2000. Evaluation of tilapia (Oreochromis niloticus) in ponds lined with concrete, plastic, and earth. Special project of the Agronomy Engineering Program, Zamorano, Honduras. 18 pp.
The objective of this study was to evaluate the effect of ponds lined with plastic, concrete, and earth on tilapia reproduction. This study found that, on average, the values of fingerlings per gram of female were 2.3, 2.2, and 1.8 for tanks lined with plastic, concrete, and earth, respectively, which did not demonstrate significant statistical differences. The cost of production per fingerling was L (lempira) 0.027, 0.021, and 0.021 for tanks lined with plastic, concrete, and earth, respectively.
