RAS ex­perts build feed re­search cen­tre

Fish Farmer - - News -

MAL­TESE com­pany AquaBioTech Group has com­pleted a re­search fa­cil­ity in the Nether­lands for the feed com­pany All­tech Cop­pens.

The All­tech Cop­pens Aqua Cen­tre, sited in Valkenswaard, com­prises a num­ber of state of the art re­cir­cu­lat­ing aqua­cul­ture sys­tems (RAS) de­signed to run si­mul­ta­ne­ous nutri­tion tri­als for a va­ri­ety of species.

Each RAS unit has been cus­tom de­signed so feed tri­als can be car­ried out in both salt­wa­ter and fresh­wa­ter con­di­tions for species such as sal­mon, trout and cat­fish, with tem­per­a­tures rang­ing from six to 28 deg C.

The fa­cil­ity con­sists of 60 tanks in four sep­a­rate sys­tems, with the op­tion to pair th­ese, mak­ing two larger sys­tems for in­creased repli­ca­tion pur­poses.

The sys­tems are de­signed to op­er­ate at com­mer­cial level stock­ing den­si­ties and in­clude sev­eral ad­di­tional fea­tures for ease of hus­bandry prac­tices.

For ex­am­ple, a par­tial tank drainage sys­tem is in­cor­po­rated into the small sys­tems to al­low for some tanks to drain and run at 50 per cent ca­pac­ity, while re­tain­ing the wa­ter in the sys­tems to in­crease wa­ter util­i­sa­tion and en­ergy con­sump­tion ef­fi­cien­cies.

The AquaBioTech Group, which has de­signed and built RAS sys­tems for cus­tomers across the world, will pro­vide re­mote tech­ni­cal sup­port for the cen­tre.
