In the 1970s, smolt were released with an average size of about 30 grams. Today, the average size is 100 grams. At the same time, the fish groups have grown bigger - much bigger - and thus also their economic value. Smoltifcation is more important than ever before.
SmoltTimer measures the fish’s smoltification status using genetic analyses of gill tissue. Experience data from more than 700 smolt groups show that SmoltTimer provides more reliable measurements than other smolt analyses, and fish groups that are released at the correct SmoltTimer values have better RGI and lower mortality.
