Baskets caught river fish (6)
I believe the answer is:
creels
'baskets' is the definition.
(creel is a kind of basket)
'caught river fish' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'river' becomes 'r' (abbreviation for river).
'fish' becomes 'eels' (eel is a type of fish).
'c'+'r'+'eels'='CREELS'
(Other definitions for creels that I've seen before include "Wicker baskets to hold fish" , "Fish-baskets" , "Fishermen use" , "Wicker baskets for fishermen" .)
