Catfish need about two pounds of feed to produce one pound of live weight. Mississippi is home to 100,000 acres (400 km 2) of catfish ponds, the
Fry can grow about 1 in (2.5 cm) per week, [36] and by late July the fingerlings are around 5–6 in (13–15 cm) long. [33] Their rate of growth is variable and highly dependent on food abundance. Higher growth rates occur in areas where food is not limited. The feeding behavior of fingerlings is quite different from that of older juveniles ...

[ 3 ] This family previously included fish that are now classified under Pseudopimelodidae (previously subfamily Pseudopimelodinae) and Heptapteridae (previously subfamily Rhamdiinae). [ 3 ]
The vulture catfish is so named because it is an active scavenger, seeking carcasses in its native waterways to consume in shoals; its feeding action promotes the skeletonization of its food items - they are able to consume all the muscles and viscera from an 80 kilograms (180 lb) cadaver within half an hour - though it apparently avoids ...
