One of the most popular and
beautiful fish in British waters,
the Tench is an olive coloured fish
with slightly golden fins. It can be
found in a wide variety of canals,
rivers, lakes and reservoirs but
tends to prefer in the larger,
slower brackish waters. The Tench is
known for its ability to survive in
relatively low oxygen conditions
such as those found during the
hottest summers when the waters can
start to stagnate.
There is also a golden variety of
the Tench, although these are much
smaller, far less common and are
normally stocked in ornamental
ponds.
Like the majority of coarse fish
Tench feed mainly on small insects,
larvae and algae when they are young
whilst the adults will also eat
water snails, pea mussels, water
shrimps as well as
most of the baits commonly used by
anglers.
They predominantly feed at dawn and
dusk, where they can be seen feeding
in at little as 10 inches of water.
They are also known for producing
the tiny 'fizzing' bubbles that can
be seen bubbling on the surface of
many still-waters, they do this by
feeding in an almost upright
position or on their heads, this
releases tiny bubbles of gas from
the silt which then go through the
fishes mouth and out through the
gill covers producing the 'fizzing'
effect. |
