Culture Growth

Growth, population size, and survival of resident largemouth bass (Micropterus salmoides) were estimated before, during, and after the cage culture of Salmo gairdneri and Ictalurus punctatus. Growth in length, length–weight relationship, and condition factor were similar among the periods; however, abundance and survival of largemouth bass increased through the 3 yr of investigation. Stomach content analyses showed that the bass fed on fishes (mostly Lepomis macrochirus), crayfish, insects, and zooplankton (predominantly entomostracans). Increase in the standing crops of L. macrochirus and entomostracans during the study periods have provided forage to the increased bass population and thus resulted in greater survival of the young and adult bass of the cage culture and postcage culture periods. Key words: largemouth bass, Micropterus salmoides, cage culture, growth, abundance, survival

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.

<em>Abstract.</em>—An investigation of historical fisheries information for pools 4–13 of the upper Mississippi River (UMR) was conducted to 1) determine the pre-1938 relative abundance and distribution of bluegill <em>Lepomis macrochirus </em>and largemouth bass <em>Micropterus salmoides, </em>2) determine the composition and relative abundance of the preimpoundment fish assemblage, and 3) determine if a shift in frequency of occurrence and relative abundance has occurred due to impoundment.

Fourteen species of freshwater fish were trained to execute a simple conditioned response in a shuttle box – to move in response to light to avoid an electrical shock. There was no relation between learning ability and phylogenetic position. Better learners included striped bass (Morone saxatilis), bigmouth buffalo (Ictiohus cyprinellus), common carp (Cyprinus carpio), and channel catfish (Ictalurus punctatus). Bluegill (Lepomis macrochirus) and northern pike (Esoxlucius) were poor learners. Yellow perch (Perca flavescens) and redbelly tilapia (Tilapia zilli) could not be trained. Some fish retained their learned behavior for months, although performance deteriorated with time. Older channel catfish learned better than juveniles, but there was no difference between juvenile and older largemouth bass (Micropterus salmoides). Temperature (18–28 °C) and feeding level (ranging from starvation for 25 d to ad libitum) did not affect learning of channel catfish, but the protozoan disease, ichthyophthiriasis, and perhaps our treatment of fish for the disease retarded it.
