Very low numbers of largemouth bass were collected from Records Pond in 2004, but by 2007 bass numbers had increased. The most abundant size group was 12- to 15-inch fish and average weights were good. A statewide angler survey indicated that angler trips fell from 9,160 in 1998 to 5,864 by 2003. However, the total catch (all species combined) per trip between the two surveys remained the same with increases in crappie, chain pickerel, and white perch catches.

Numbers of bluegill and black crappie have also increased in recent years. Bluegill ranged in size from 3.5 to 9 inches and had higher than average weights. Black crappie were less abundant but fish up to 12 inches in length were collected.

The redear sunfish, a recently introduced species in Delaware ponds, was originally collected in this pond in 2004 and appears to have become established. This species has been recorded in Trap Pond upstream of Records Pond and numerous citation-size redear (minimum weight 1 lb.) have been reported to the Delaware Sportfishing Tournament in recent years from Records Pond. Growth of redear sunfish is much faster than bluegill. Redear sunfish ranging in size from 8 to 10 inches were evident, but this fish can grow to over 12 inches. The current Delaware State record is 3 lbs 1 oz from Diamond Pond.

Creek chubsucker were common in Records Pond with brown bullhead, golden shiners, and chain pickerel being less frequent. American eel and yellow bullhead were also present.
