Pectoral Spine

<em>Abstract</em>.—We have been examining proximate (functional morphology) and ultimate factors (survival from predation) relating to the pectoral spine in channel catfish <em>Ictalurus punctatus</em>. We briefly review functional morphology of the spine in channel catfish and then add new data on morphology in other ictalurids, including interpretation of the relatively smooth anterior and armored posterior profiles of the spine, functions of the various pectoral spine muscles, and new details about the mechanism of stridulatory sound production. Binding, locking, and production of stridulation sounds by the spine utilize derived processes on the spine base (dorsal, anterior, and ventral processes) that mate with counterparts within the pectoral girdle. Stridulation sounds are produced as a series of individual pulses during a forward pectoral fin sweep (abduction), and we provide evidence that each pulse is produced by a small amplitude forward movement, a slip-stick movement similar to bowing a violin. An anti-predator adaptation can work as a deterrent that reduces the probability of attack and as a defense that reduces the risk of mortality. Previous work indicated that the spine functions in defense. Intact channel catfish have a threefold greater chance of surviving a session with a largemouth bass <em>Micropterus salmoides</em> predator as comparably sized individuals with clipped spines. The question of whether the spine reduces the probability of attack had not been investigated. We presented bluegills <em>Lepomis macrochirus</em> and channel catfish to largemouth bass and found that largemouth bass consume more bluegills than channel catfish in a choice situation. Thus, experience with the pectoral spines likely deters attack, particularly if other species are available, and the spine increases the probability of surviving attack by complicating ingestion and possibly by the production of distress calls. Survival advantages accruing from the spine appear to have lead to the evolution of complex adaptations that permit locking and sound production.

Catch Rates

<em>Abstract.-</em>Demographic studies have indicated that, since 1990, Kentucky’s urban population has experienced an 18% increase while its rural population has expanded by less than 1%. These demographic changes, coupled with a decline in fishing license sales, focused the need to develop and increase fishing opportunities in and around urban areas. In 2005, the Kentucky Department of Fish and Wildlife Resources initiated a pilot urban fishing program aimed at providing urban residents with high quality fishing opportunities close to home. Five pilot lakes, located within four of Kentucky’s most populated counties, were selected to receive regular stockings of rainbow trout <em>Oncorhynchus mykiss</em>, channel catfish <em>Ictalurus punctatus</em>, largemouth bass <em>Micropterus salmoides</em>, and hybrid bluegill <em>Lepomis macrochirus </em>x <em>L. cyanellus</em>. Rainbow trout were stocked at each lake in April and October. Channel catfish, largemouth bass, and hybrid bluegill were stocked in May and June. Monthly stocking rates were 202 trout/ha, 34 channel catfish/ha, 12 largemouth bass/ha, and 81 hybrid bluegill/ha. Creel and angler attitude surveys were conducted at two of the pilot lakes from April through August 2006 to determine angler catch and satisfaction. Although fishing pressure at these two lakes was high, most anglers practiced catch and release. Catch rates were 1.03 fish/h at Stein Lake and 0.79 fish/h at Upper Sportsman’s Lake. Angler attitude survey results indicated that the majority of anglers interviewed were not aware of the program and did not know that regular fish stockings were occurring at the lakes. The typical angler fishing these lakes was a white male between the ages of 30 and 49, who was satisfied with his fishing experience regardless of the number or size of fish caught. Further studies need to be completed to compare results from this study, and to refine stocking and marketing techniques used in the program.
