Aquaculture engineering requires knowledge of the many general aspects of engineering such as material technology, building design and construction, mechanical engineering, and environmental engineering. In comprehensive book now in its second edition, author Odd-Ivar Lekang introduces these principles and demonstrates how such technical knowledge can be applied to aquaculture systems"--$cProvided by publisher. 606 $aAquacultural engineering 615 0$aAquacultural engineering. 676 $a639.8 686 $aTEC049000$2bisacsh 700 $aLekang$b Odd-Ivar$0865322 701 $aLekang$b Odd-Ivar$0865322 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910786047803321 996 $aAquaculture engineering$91931413 997 $aUNINA
