Lipid requirement of bay snook (Petenia splendida Günther, 1862) juveniles

Latin American Journal of Aquatic Research, 2020
This research study is focused on the lipid requirements of Petenia splendida (0.65 ± 0.19 g) juveniles. Fish were fed with trout commercial diet (Silver Cup™ - 45% protein and 16% lipids), as control diet - CD (which is usually used to feed this species at commercial scale), and four isoproteic (45% crude protein) diet formulated with different lipid ...

EFECTO DE LA 17α-METILTESTOSTERONA EN LA MASCULINIZACIÓN DE LA MOJARRA NATIVA Petenia splendida

Kuxulkab', 2017
La mojarra nativa 'Petenia splendida' (tenguayaca) es un pez dulceacuícola de importancia tradicional y comercial para el estado de Tabasco, México. Se ha observado que se reproduce a tallas muy pequeñas, impidiendo el buen crecimiento de los peces en un sistema de cultivo por lo cual se realizó un estudio para determinar la dosis necesaria para la ...

[The mitotic and meiotic chromosomes of the tropical fish Petenia splendida (Cichlidae)].

Revista de biologia tropical, 2009
The karyotype of bay snook, Petenia splendida, is described based on mitotic and meiotic stages of sixty larvae and twelve juveniles from Tabasco, Mexico. Standard cytological procedures with minor modifications were followed to obtain mitotic and meiotic chromosome spreads.

Masculinization of the Native Bay Snook, Petenia splendida, Using Oral Administration of the Synthetic Steroid 17α‐methyltestosterone

Journal of the World Aquaculture Society, 2017
AbstractThe possibility of inducing sex reversal in bay snook, Petenia splendida, was evaluated to generate a protocol aimed at producing single‐sex populations (100% males) and improving farming conditions for this species. This popular staple food is a cichlid fish native to Central America, with aquaculture potential.

Los cromosomas mitóticos y meióticos del pez tropical Petenia splendida (Cichlidae)

Revista de Biología Tropical, 2006
Para describir los cromosomas del cariotipo en mitosis y meiosis de la mojarra tenguayaca P. splendida, se procesaron 60 larvas y doce jóvenes (seis hembras y seis machos) procedentes de Tabasco, México. Se emplearon los procedimientos citológicos clásicos para peces pequeños y grandes, con algunas modificaciones que permitieron obtener campos ...

Evaluation of Larval Growth and Survival in Mexican Mojarra, Cichlasoma urophthalmus, and Bay Snook, Petenia splendida, Under Different Initial Stocking Densities

Journal of the World Aquaculture Society, 2009
Abstract Two experiments were conducted to evaluate the initial stocking density in larvae of Bay snook, Petenia splendida, and Mexican mojarra, Cichlasoma urophthalmus, using a recirculation system. Five initial stocking densities (0.5, 1, 5, 10, and 20 larvae/L) were evaluated by triplicate for 45 d.
