Genetic Improvement of Cultured Marine Finfish

Genetic improvement of marine fish - which method for industry?

“…(Knibb et al 1998a). Accordingly, in selection lines, it is prudent to record a variety of commercial traits, even those not under deliberate selection.…”

“…in gynogenetic research) and as elements in genetic protection, we isolated by inbreeding and back-crossing a variety of spontaneous mutations causing visible phenotypes (including yellow and white body colour; Knibb et al 1998a). For the seabream genetics programme at Eilat, there was some attempt to formalize research on qualitative traits and new mutations.…”

“…Some intergeneric Sparidae hybrids had vestigial gonads that were also sterile (Gorshkov et al 1998), but hybrids failed to show growth acceleration (Knibb et al 1998a). Reproductive constraints Technical constraints · producing monosex hybrid offspring; · achieving superior performance or heterosis; · achieving sterility.…”

“…Given the large number of attempts to produce new ®sh hybrids, remarkably few (apparently less than 1%) have resulted in sustained commercial production (Wu 1990;Purdom 1993;Hulata 1995b;Knibb et al 1998a). Given the large number of attempts to produce new ®sh hybrids, remarkably few (apparently less than 1%) have resulted in sustained commercial production (Wu 1990;Purdom 1993;Hulata 1995b;Knibb et al 1998a).…”

“…Some triploid Sparidae have small and sterile gonads, but with little or even contrary indication for somatic growth acceleration (Gorshkov et al 1998;Knibb et al 1998a). Some triploid Sparidae have small and sterile gonads, but with little or even contrary indication for somatic growth acceleration (Gorshkov et al 1998;Knibb et al 1998a).…”
