The aim of this review is to identify problems, find general patterns, and extract recommendations for successful management using nontraditional biomanipulation to improve water quality. There are many obstacles that prevent traditional biomanipulation from achieving expectations: expending largely to remove planktivorous fish, reduction of external and internal phosphorus, and macrophyte re-e...

Good aquaculture practice (GAP) based carp fattening is a potential technique to obtain higher and safe fish production within shorter period in ponds of drought prone area. Sustainability this technique, however, constrained by high feed cost poor water quality. Therefore, as an overcoming effort, three diets (protein content 20%, 25% 30%) under different treatments (T1, T2 T3) were tested dur...

Field survey of Aquaculture farms in Basrah governorate was done during 2007. The study showed that there are 80 fish farm with total area 773.5 donum, while it 16 2003. 75 % the were less than 25000 m² (10 donum). 53.9 excavated pond, 34.2% concentration by half ground pools and 11.8 dyke pond.

Abstract Silver Carp Hypophthalmichthys molitrix have expanded their range to encompass most of the Mississippi River basin, including much Missouri River. However, there is a paucity information concerning in especially tributaries. Little known about how function these tributaries or connectivity with main‐stem river can influence population demographics within either system. The Kansas tribu...
