The author, Gavin Johnston who has many years' experience of farming Arctic charr, teaching about and researching the species, has produced a book that is a landmark publication and an essential purchase for all those involved with the species. The book is broadly divided into three sections. The first section covers Arctic charr interactions with humans and the charr's biological requirements for cul 606 $aArctic char 606 $aAquaculture 608 $aElectronic books. 615 0$aArctic char. 615 0$aAquaculture. 676 $a639.37554 700 $aJohnston$b Gavin$0944675 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910145277003321 996 $aArctic charr aquaculture$92132531 997 $aUNINA
