Until now, many working in a hands-on capacity in the area of aquaculture have not known what the benefits of this work could be to them. This important new book redresses this situation, providing clear details of the available scientific information and the direct application of techniques under simple and practical situations. 606 $aAquaculture 606 $aAquatic animals$xGenetics 615 0$aAquaculture. 615 0$aAquatic animals$xGenetics. 676 $a639.3 676 $a639.8 700 $aLutz$b Charles Gregory$f1957-$0881322 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a996208270503316 996 $aPractical genetics for aquaculture$91968251 997 $aUNISA 999 $aEbook
