After casting, lands more fish (3,6)
I believe the answer is:
red salmon
'fish' is the definition.
(I know that red salmon is a type of fish)
'after casting lands more' is the wordplay.
'after casting' indicates anagramming the letters.
'lands'+'more'='landsmore'
'landsmore' is an anagram of 'RED SALMON'.
(Other definitions for red salmon that I've seen before include "Sockeye" , "fish" .)
