Finfish Aquaculture Testing

Neogen provide speciality testing and analytical services to the salmon aquaculture industry.


Neogen offers a salmon gill ATPase assay that shows when salmon parr have undergone one of the most important changes of the smoltification process; the ability to expel excess salt from their tissues. This enables salmon farmers to determine with greater precision when smolts are ready to go to sea, resulting in fewer mortalities and fish that thrive and grow well in their salt water pens. Neogen’s ATPase assay can therefore result in increased profitability.

During smoltification gill ATPase activity increases between two and five fold, preparing fish for exposure to higher salt levels. Neogen’s ATPase assay measures the rate at which this protein is working and is therefore an accurate and fast indicator of readiness to go to sea.

Salmon smolts instinctively know when these changes have taken place and in the case of wild fish, transit between fresh and salt water at the appropriate time. Salmon farmers have to decide when fish are ready to be transferred from fresh to salt water pens. If salmon are transferred too early then mortality can be high and fish fail to thrive, resulting in lower yields at harvest.

Lysozyme Activity, Endochitinase and Exochitinase

Neogen uses quantitative kinetic fluorescent enzyme assay testing methods for triplicate determination of Lysozyme Activity, Endochitinase and Exochitinase in fish mucus.
