The culture of cichlids of southeastern Mexico

Abstract

In Mexico, aquaculture is a growing sector, but it continues to be developed using non‐native species. The natural ecosystems of the lowland humid tropics of southeastern Mexico have been well‐described by ecologists and are host to a very high diversity of species, including a substantial ichthyofauna. Cichlid fish, commonly known in southeast Mexico as ‘mojarras’, are an important fish resource and are widely consumed. Several species are now under considerable pressure and consequently the generation of biotechnology for the culture of native fish species is necessary and worthwhile. This paper examines and describes the experiences and knowledge generated over recent years regarding the aquaculture of native cichlids in the southeast of Mexico. Although the scientific and technological capacity for research and development for native species culture exists, there is an evident lack of information on new technologies among producers, as scientific research is not translating fully into technical assistance. Research and extension should be emphasized in order to develop a comprehensive knowledge base on native species and to enable their cultivation.

Effect of light intensity and photoperiod on growth and survival of the Mexican cichlid, Cichlasoma beani in culture conditions

“…Corresponding editor: Fernando Vega-Villasante Páramo-Delgadillo, 2008). Once a culture protocol is established it can contribute to the biodiversity conservation by presenting an alternative to unregulated fishing (Dudgeon et al, 2006).…”

Effect of Stocking Density on Growth, Survival, and Condition of the Mexican Cichlid Cichlasoma beani

“…The development of culture techniques has been a successful strategy to protect species (Pérez-Sánchez and Páramo-Delgadillo 2008;Martinez-Cardenas and Purser 2011). Suboptimal stocking densities can cause hierarchical social stress because of territorial and food competition.…”

Tiempo y dosis óptimas de fluoximesterona, para masculinización de crías del pez maya Cichlasoma urophthalmus (Percidae: Cichlidae)

“…Tales poblaciones, ofrecen diferentes beneficios, incluyendo un crecimiento rápido y el control de la reproducción no deseada, evitando de este modo el desvío de energía a la producción de gametos, y promoviendo el incremento de la masa muscular y talla. Con ello se evita a su vez, que los tiempos de cultivo puedan prolongarse forma considerable (Green et al, 1997) Por otro lado, la mojarra latinoamericana o cíclido Maya C. urophthalmus, es una de las mojarras nativas del sureste mexicano más ampliamente estudiada, con fines de cultivo (Martínez-Palacios & Ross, 1994;Pérez-Sánchez & Páramo-Delgadillo, 2008). Esta especie tiene una tasa de fecundidad de 2 000 a 4 000 huevos por desove, permitiendo una buena producción de cría en comparación al de las tilapias (Morales, 1991).…”
