FISH CULTURE

Fish In Enchaining Food World. ( Electroplated from presentation materials of FAO [at] World Seafood Congress to- 7 [in] Dublin, Irlandia September 2007) Compared to other food materials, product increase of fishery represent quickest [is] its growth. This achievement especially because efficacy of fishery of conducting [in] various state, though globally fishery product catch to experience of degradation since in the middle of the 80. China Producer and Biggest Consumer Fish [is] Amount of earthling continue to increase, so that requirement of food materials production of[is including fishery will continue to increase. Consumer of fish besides human being [is] livestock and up to now global requirement [of] livestock food-stuff will from fish relative remain to. Even fishery product catch to tend to to go down, but as a whole natural fishery product [of] increase so that fish pasokan upon which human being food increasing. Total increase [of] production [of] fast effect [of] him growt

Volute Centrifugal pumps for fishpond. Pump volute centrifugal as any centrifugal pump use speed ( acelerasi ) centrifugal to give gumption [at] dilution. [Gift/ giving] of name pump volute come from form [at] surface in from pump shroud. Shroud have a[n surface in which in form of volute. Dilution go out from propeller gaps enter area among shroud and impeller which later;then make a move to go down slowly. In pump of volute area [among/between] shroud and impeller step by step open wide so that pump outlet will reach ( coming near pump outlet ) speed of current decrease slowly and internal energy decrease. Design to wake up desain [at] pump of volute dot weigh against at one particular burden imbalance of hidraulik [at] axle bearing of impeller. Double admission filling [of] pump of volute connective [of] balance of hidraulik by pad the return two impeller return [at] each handle.
