Fish in canal almost tricked to bite last of bait (8,6)

'fish' is the definition.
(I know that Atlantic salmon is a type of salmon)

'in canal almost tricked to bite last of bait' is the wordplay.
'tricked' is an anagram indicator (I've seen 'tricks' mean this).
'to bite' means one lot of letters goes inside another (some letters bite around others).
'last of' says to take the final letters.
The last letter of 'bait' is 't'.
'in'+'canal'+'almost'='incanalalmost'
'incanalalmost' with letters rearranged gives 'alanticsalmon'.
'alanticsalmon' going around 't' is 'ATLANTIC SALMON'.
