A complete range of micro diet particles for Marine Fish Hatcheries

GEMMA Diamond has been designed to give juveniles the best start by as- suring fast and efficient growth and low feed conversion under pre-growing conditions. GEMMA Diamond contains a high level of multiple marine proteins and has an improved attractability and protein/energy ration for fast- track growth thanks to the low temperature extrusion production process. Pre-growing economics are also improved.

GEMMA Diamond is based on the principles and formulation of PRO - TEC which supports the juveniles in facing stressful events. Consequently, GEMMA Diamond can also be offered prior to stress-induced events.

GEMMA Diamond comes in five pellet sizes - 0.8mm, 1.0mm, 1.2mm, 1.5mm and 1.8mm - to follow on from GEMMA Wean.
