“…Physical tagging could be used to identify fish both on the inside of cages to enable farmers to monitor fish movements between production units, and the outside of cages to enable managers to identify escapees. Passive integrated transponder tags are commonly used in aquaculture for broodfish identification (Jackson et al 2003) and for identification of large numbers of off-spring in selection programs (Powell et al 2008). In addition, coded wire tags have been used extensively for identification of fish groups in the wild (Brennan et al 2007, Bumgarner et al 2009).…”

Aquaculture management authorities require the ability to identify the farm of origin for escaped fish. Physical tagging is routinely conducted for domesticated animals (e.g. sheep and cattle); however, there are considerable logistical, animal welfare and economic issues that challenge the feasibility of physically tagging all farmed fish. A 'DNA stand-by method' for identification of escaped Atlantic salmon, back to the cage and farm of origin, was established at the Institute of Marine Research in Norway. In addition, proof-of-concept for the method has been demonstrated to be able to trace rainbow trout and Atlantic cod escapees back to their farm source. The combined sampling, genotyping and statistical analysis on which the method is based has been implemented successfully in the identification of fish farm escapees in Norway, resulting in fines for companies found in breach of regulations. This paper reviews the method, its challenges, and some previously considered alternatives. It is concluded that as the method has been successful for the 3 major species farmed in Norway, each with contrasting production logistics including breeding programs, state of domestication, and magnitude of production, the DNA stand-by method can be applicable to identification of fish farm escapees for a wide range of aquaculture species in all regions of the world.

“…Atlantic halibut aquaculture is still in its infancy and, since husbandry and production methods are not completely optimized, genetic contributions to halibut broodstock performance are largely unexplored. Analyses of genetic variability in F 1 fish retained as future aquaculture broodstock have demonstrated the presence of large family groups among these fish (Stefansson et al 2001;Jackson et al 2003), which could easily lead to inbreeding if crosses are not closely monitored. Additionally, the long time (5-7 years) until sexual maturation in halibut (Haug 1990) means that decades will be required to achieve production gains through standard broodstock selection.…”

A genetic linkage map has been constructed for Atlantic halibut on the basis of 258 microsatellites and 346 AFLPs. Twenty-four linkage groups were identified, consistent with the 24 chromosomes seen in chromosome spreads. The total map distance is 1562.2 cM in the female and 1459.6 cM in the male with an average resolution of 4.3 and 3.5 cM, respectively. Using diploid gynogens, we estimated centromere locations in 19 of 24 linkage groups. Overall recombination in the female was approximately twice that of the male; however, this trend was not consistent along the linkage groups. In the centromeric regions, females had 11-17.5 times the recombination of the males, whereas this trend reversed toward the distal end with males having three times the recombination of the females. Correspondingly, in the male, markers clustered toward the centromeric region with 50% of markers within 20 cM of the putative centromere, whereas 35% of markers in the female were found between 60 and 80 cM from the putative centromere. Limited interspecies comparisons within Japanese flounder and Tetraodon nigroviridis revealed blocks of conservation in sequence and marker order, although regions of chromosomal rearrangement were also apparent.

“…Esta técnica también ha sido exitosamente usada en poblaciones naturales en el bacalao del Atlántico Gadus morhua donde identificaron el parentesco a 300 alevinos mediante 8 marcadores microsatélites, logrando evaluar la contribución parental del stock de reproductores mantenidos en cautiverio en estanques comerciales (Herlin et al, 2008). Así como en el rodaballo (Hippoglossus hipoglossus) donde mediante 5 marcadores microsatélites identificaron el parentesco a 145 alevines, logrando evaluar el impacto de selección de los individuos sobre la diversidad genética de la progenie F1 a ser utilizados en futuros stock de reproductores (Jackson et al, 2003). …”

RESUMENUn set de seis loci microsatélites fue utilizado como herramienta molecular para identificar el genotipo de los reproductores y asignar el parentesco a diferentes familias de Pseudoplatystoma fasciatum. Las progenies cultivadas en situación comunal fueron obtenidas por la reproducción inducida de los óvulos de una hembra con un pool de esperma de cuatro machos. Todos los loci microsatélites mostraron apropiada amplificación y polimorfismo, con alelos diagnósticos o combinación de alelos para identificar a los reproductores y asignar el parentesco sin riesgo a equivocarse. Los alelos nulos encontrados en los loci Pcor 7 y Pcor 8, no dificultaron la identificación de la progenie. Se obtuvieron cuatro familias de medio-hermanos (en cada etapa de muestreo). Resultados de este estudio demuestran la utilidad de las herramientas genéticas en la asignación de parentesco en familias de Pseudoplatystoma fasciatum cultivadas comunalmente.PALABRAS CLAVES: Pseudoplatystoma fasciatum, piscicultura, microsatélites, genotipo, parentesco. PARENTAGE ASSIGNMENT IN LARVAL Pseudoplatystoma fasciatum (Linnaeus, 1766) PRODUCED IN CAPTIVITY ABSTRACTA set of six microsatellite loci was used to identify the genotype of the breeder and assign kinship in different families of Pseudoplatystoma fasciatum. The progenies bred communally were obtained by combining the eggs of a female with a pool of sperm from four males. All microsatellite loci showed appropriate amplification and polymorphism with unique alleles or a combination of alleles to identify the breeder and assign kinship without risk of error. Null alleles were encountered at loci Pcor 7 and Pcor 8, but there was no difficulty in identifying progeny. Four half-sibling groups were tested (at each stage of sampling). Results of this study demonstrate the utility of genetic tools in assigning parentage in families of Pseudoplatystoma fasciatum bred communally.
