Automating & maximising fish roe extraction
Our latest case study focuses on an enquiry we received to supply five flexible impeller pumps to enable the smooth and hygienic transfer of fish roe suspended in water .
Our client specified that the pumps had to be capable of roe transfer at 36,000 litres per hour , while also operating slowly and gently to ensure that the fish eggs were not broken or damaged during the process .
What is fish roe ?
It ’ s actually the eggs which are collected from marine animals . These are high in nutrients and Omega 3 and are often used in dishes as a raw ingredient , or can be a very expensive delicacy - caviar .

All female fish have roe and these eggs can be sourced internally from two sacs - one on each side of the belly , or from an external egg mass . Fish roe can be taken from any type of fish like salmon , trout , cod , paddlefish or whitefish . The term roe also applies to eggs from other marine animals like scallops , lobsters and shrimp .
Is it the same as caviar ?
All fish eggs are called roe , but not all roe is caviar . The term caviar only applies to fish roe from the sturgeon family , Acipenseridae . Salmon roe and the roe from whitefish , cod , trout , red caviar , ikura , tobiko and so on are considered caviar substitutes and not caviar .
Clearly , fish roe is a highly prized and very valuable commodity . Extraction , fish egg transfer and cleaning make this excellent product valuable for human consumption , as well as offering enormous opportunities for profitable use in other food production applications such as fish meal .
This is why food companies are constantly looking for the most efficient , hygienic and streamlined method of extraction and roe transfer , to harvest the hidden value from these unique products .
Our client wanted to boost the efficiency of their fish egg transfer process , by automating extraction
