The char ( Salvelinus ) are a genus from the salmon fish family (Salmonidae).

description

The genus char belongs to the salmon family and has the adipose fin typical of all salmonids . The physique is streamlined. The genus is characterized by an extraordinary diversity among the individual species, which is even greater than that of other salmon fish genera. Therefore the systematics of the char has not yet been finally clarified.

habitat

The char can be found all over the northern hemisphere. They usually prefer cold, clear fresh water. Only a few species live anadromously (migrating from salt water to fresh water to spawn). Char are the freshwater fish that have penetrated the furthest into arctic waters.

Due to their natural isolation, Arctic char form trunks that differ slightly from lake to lake in terms of their color.

Economic importance as edible fish

Char are considered excellent food fish . Due to the high demands placed on ecological conditions, re-rearing and rearing is difficult. Therefore, only a comparatively small number of char come on the market.

In the last few decades, and increasingly so in the last few years, char production has also become more important in aquaculture . The most important European producer country is currently Iceland . Like trout, char can be raised in ponds, basins and canals ( pond management ), achieve significantly higher market prices than rainbow trout and are therefore of interest to pond owners. In quite a few trout pond farms, up to 30 percent and more of sales are now achieved with char.

The rearing of char does not differ significantly from the rearing of rainbow trout in terms of feeding, keeping and water requirements . However, spawning fish management is more difficult, and there are higher hatching and rearing losses. This also makes the eggs and saplings more expensive than trout . The sales revenue for live or kitchen-ready char is on average around a third higher than for trout.
