“…Moreover, triploid common carp are prone to loss of fitness such as survival and growth (Cherfas et al, 1994;Basavaraju et al, 2002), conceivably compromising their ability to serve as Judas fish.…”

“…In species in which the onset of sexual maturity is associated with reduced growth, triploidy provides a means of preventing energy allocation toward gonad development since triploids tend to be effectively sterile. For this reason, triploidy has been used to enhance production in several aquaculture species including common carp (Basavaraju et al, 2002), channel catfish (Wolters et al, 1982), and rainbow trout (Bye and Lincoln, 1986). Triploids may also exhibit higher survival, hybrid vigor, sterility, and greater disease resistance (Parsons et al, 1986;Dorson et al, 1991).…”

Implications• Aquaculture is the fastest-growing global agricultural industry as a result of advances in fish genetics, nutrition, feeds, culture systems, and management.• The genetic and phenotypic diversity of fish has been capitalized to yield rapid gains in aquaculture production through a coordination of genetics, nutrition, and management such that aquaculture now produces more than half of the fish consumed by humans globally © Small, Hardy, and Tucker.

“…Adicionalmente, el aporte de alimento de alta calidad junto con rápidas tasas de crecimiento, a menudo reducen la edad a la cual la maduración sexual da inicio en organismos cultivados; comparado con el desempeño de los silvestres de la misma especie. La maduración temprana, representa un problema potencial para el cultivo de una especie; ya que se producen poblaciones de individuos maduros pero de pequeño tamaño, con un bajo potencial de crecimiento (Basavaraju et al, 2002;Manning et al, 2004;Piferrer et al, 2009).…”

RESUMEN.La triploidía se ha convertido en una herramienta recomendable para la acuicultura, ya que los problemas asociados con la maduración gonadal pueden ser eliminados o bien reducidos mediante la producción de peces triploides, los cuales son funcionalmente estériles. Aunque la posibilidad de esterilizar una gran cantidad de individuos ha convertido a la triploidía en un tema relevante económicamente, los cambios fisiológicos provocados por la adición de un tercer juego de cromosomas, ofrecen la posibilidad de estudiar procesos básicos en peces con diferente nivel de ploidía. A nivel fisiológico, la triploidía está estrechamente relacionada con el incremento del tamaño celular y sus repercusiones en varios procesos metabólicos y bioquímicos. El objetivo del presente trabajo es describir las principales consecuencias fisiológicas reportadas para peces marinos y dulceacuícolas, resultado de la inducción a la triploidía. Comprender estas consecuencias es de vital importancia para maximizar el desempeño de los peces triploides durante el cultivo.

Triploidy has become a recommended tool for aquaculture since problems associated with gonadal maturation can be eliminated or reduced by producing triploid fish, which are functionally sterile. Although the possibility of sterilizing a large number of individuals has helped for triploidy to become an important issue economically, the physiological changes caused by the addition of a third set of chromosomes provides the opportunity to study basic processes in fish with a higher ploidy status. At physiological level the consequences of triploidy are closely related to the increase of cell size and its subsequent impact on various metabolic and biochemical processes. The aim of this work is to describe the main physiological consequences reported for marine and freshwater fishes resulting from the induction of triploidy. Understanding these consequences is of vital importance to maximize the performance of triploid fish under culture.
