Inducción al desove en hembras del pargo mancha, Lutjanus guttatus (Steindachner, 1869).

Autor: Silvia Valverde Chavarría, Jorge Boza Abarca

Publikováno v: Uniciencia, Vol 15, Iss 1, Pp 65-69 (1998)

Se estudió el efecto del extracto de pituitaria de carpa (EPC) en 6 hembras maduras de pargo mancha, L. guttatus, capturadas con línea por pescadores artesanales en el Golfo de Nicoya. El peso de las hembras varió de 1,7 – 2,0 Kg. Tres hembras s

Changes in digestive enzymes activities during the initial ontogeny of wolf cichlid, Parachromis dovii (Perciformes: Cichlidae)

Autor: Carlos Alfonso Frías-Quintana, Carlos Alfonso Álvarez-González, Rocío Guerrero-Zárate, Silvia Valverde-Chavarría, Juan B. Ulloa-Rojas

Publikováno v: Neotropical Ichthyology, Vol 17, Iss 1 (2019)

ABSTRACT Wolf cichlid, Parachromis dovii, is a species with a high potential for aquaculture in Central America; however, the knowledge of the digestive physiology in larvae period is limited. For these reason, this study evaluated the changes on dig

Growth and alkaline digestive proteases activity of Parachromis dovii larvae fed live prey and formulated diets with different protein sources

Autor: Juan Bautista Ulloa Rojas, Mauricio Herrera Campos, Silvia Valverde Chavarria

Publikováno v: AquaTechnica, Vol 4, Iss 2, Pp 75-84 (2022)

ABSTRACT | Parachromis dovii is a carnivorous cichlid fish from Central America, which easily accepts formulated feeds since exogenous feeding starts; however, its larval growth is lower than that obtained using live food. For this reason, the effect
