Sus­tain­able feed product for shrimp

Fish Farmer - - News -

A NEW feed ad­di­tive for shrimp has been launched in the Bel­gian city of An­twerp, at the world’s first plant pro­duc­ing spe­cially de­signed me­thio­n­ine, an amino acid.

Man­u­fac­tured by Ger­man firm Evonik, the product, called Aquavi Met-Met, is a dipep­tide made up of two DL-me­thio­n­ine mol­e­cules.

It achieves the same weight in­crease in shrimp and crus­taceans as con­ven­tional me­thio­n­ine sources, but uses only half the ac­tive sub­stance.

This is mainly due to the fact that the dipep­tide must be en­zy­mat­i­cally bro­ken down in the di­ges­tive sys­tem of the shrimp and is there­fore avail­able for pro­tein syn­the­sis at the right time. That in turn means that a higher share can be pro­cessed.

Aquavi Met-Met is con­sid­er­ably less water-sol­u­ble than other me­thio­n­ine sources and there­fore does not leach out of feed as quickly. This re­lieves the bur­den on the water.

The An­twerp plant’s mod­u­lar de­sign al­lows for in­creas­ing pro­duc­tion ca­pac­ity in or­der to meet cus­tomer de­mand.

‘With Aquavi MetMet, we are launch­ing an­other product for healthy and sus­tain­able an­i­mal nu­tri­tion,’ said Dr Reiner Beste, chair­man of Evonik, at the in­au­gu­ra­tion cer­e­mony.

‘Based on our sci­en­tific and tech­no­log­i­cal ex­per­tise, we have de­vel­oped a product in­no­va­tion that we can now of­fer to our cus­tomers world­wide.’

Since shrimp farm­ing is con­cen­trated in warmer seas close to the equa­tor, the main mar­kets for the ad­di­tive are lo­cated in Asia, as well as in South and Cen­tral Amer­ica.

Evonik is al­ready be­gin­ning to sup­ply cus­tomers from these re­gions with the new product as the plant is ramped up to ca­pac­ity.

‘We are pleased that Evonik built the first pro­duc­tion fa­cil­ity for Aquavi Met-Met in An­twerp,’ said Frank Da­man, Evonik site man­ager in An­twerp.

‘The new plant af­firms our site’s key po­si­tion in Evonik’s global pro­duc­tion net­work for me­thio­n­ine.’
