AbstractMembers of the genusNeoechinorhynchusStiles & Hassall, 1905 are endoparasites of freshwater fishes, brackish water fishes, and freshwater turtles distributed worldwide. In North America, 33 species have been described. One of the most widely distributed species in the eastern United States and Canada isNeoechinorhynchus (Neoechinorhynchus) cylindratus,a common acanthocephalan that infects centrarchid fishes. In the current study, adult specimens ofN. (N) cylindratuswere collected from largemouth bass (Micropterus salmoides) from the Purificación River in northern Mexico. In the same freshwater system, two additional congeneric species (Neoechinorhynchus (Neoechinorhynchus) emyditoidesandNeoechinorhynchus (Neoechinorhynchus) panucensis) were collected and analysed. Sequences of the large subunit, internal transcribed spacers ITS1 and ITS2, 5.8S from nuclear DNA, and sequences of the cytochromecoxidase subunit I (cox1) from mitochondrial DNA were generated and aligned with other sequences obtained from GenBank. Maximum likelihood and Bayesian inference analyses inferred for each dataset showed thatN. (N) panucensis,N. (N) emyditoidesandN. (N) cylindratuswere nested within several clades, indicating that these species do not share a common ancestor. Our phylogenies also revealed that the genusNeoechinorhynchusis paraphyletic, requiring further taxonomic revision using phylogenetic systematics and re-examination of morphological and ecological data. The presence of severalN. (N) cylindratusadults in northern Mexico allowed us to typify this species for the first time using a combination of morphological and molecular characteristics. The current record shows a wide distribution range ofN. (N) cylindratusacross Canada, the United States and Mexico in the Nearctic region.

<em>Abstract</em>.—Thirteen United States fishery agencies utilized routine supplemental stocking as a means to manage largemouth bass <em>Micropterus salmoides </em>populations in large (>405-ha) reservoirs. State agencies stocking largemouth bass used two strains (i.e., northern and Florida) as well as intergrades. Largemouth bass for stocking were raised in hatcheries, lakeside nursery ponds, or both. Among states, methods used to monitor fish in hatchery ponds and lakeside nursery ponds, the date ponds were drained, and methods to enumerate fish from the ponds varied. Although most states cited bolstering weak year-classes as their main reason for routine stocking, others noted increasing genetic variability within populations and public pressure as reasons that their agencies stocked large reservoirs with largemouth bass. As agencies continue to respond to public pressures for larger fish, they should consider the possible consequences of mixing stocks of largemouth bass. With continued development of agency rearing techniques, especially in lakeside nursery ponds, methods to enumerate fish should be considered to aid in future stocking evaluations. Improved rearing and stocking techniques will allow fisheries managers to utilize resource dollars in a way that provides benefit to anglers while ensuring the sustainability of largemouth bass populations.

Management And Conservation

Largemouth Bass Micropterus salmoides, Florida Bass M. floridanus, and their intergrade are socially and economically valuable sport fish. In the southeastern United States, it is customary to age black bass (Micropterus) spp. using sagittal otoliths which requires killing the fish. Presently, fisheries managers and black bass anglers show reluctance to sacrifice large individuals. Development of a nonlethal ageing technique would not only allay concerns of sacrificing large black bass, but it could offer a pathway for new research, management, and conservation. We excised dorsal spines III–V from Largemouth Bass in Florida varying from 30–57 cm total length to evaluate the effects of the procedure on survival over 35 days. No mortalities were observed for fish with excised dorsal spines, and experiment-wide survival was 0.94 (0.87–1.00; 95% confidence interval). No significant differences in survival, weight change, or incidence of external injuries were observed between control and excised fish. The areas of spine excision healed with no visible infection or inflammation at the conclusion of the experiment. Therefore, dorsal spine removal offers managers a nonlethal option for collecting ageing structures of adult Largemouth Bass in Florida, including large individuals, and this result likely extends to other Micropterus spp. as well.

Genetic differences exist among 90 largemouth bass (Micropterus salmoides) populations from different geographic regions of the United States. Genetic variation at 28 loci was determined through the use of vertical starch gel electrophoretic analyses. Allelic polymorphism was observed at 16 of these loci. Marked differences in allele frequencies at six of these loci exist among the populations. Distinct north–south clinal distributions of the alleles at the MDH-B, SOD-A, IDH-B, and AAT-B loci suggest a possible involvement of the associated enzymes in the thermal tolerance/preference limits for this species.We conclude that one or more of these enzymes may be directly involved in temperature tolerance/preference or indirectly associated with temperature-related effects. In either instance, selection (if occurring) may be acting upon the enzyme locus or genes closely linked to it. Through a combination of ecological and genetic principles, it is becoming increasingly feasible to select or construct specific populations of marine or freshwater fish optimally suited for specific environments. Fisheries management programs would benefit from the application of these principles. Multidisciplinary approaches of this nature are essential to maximize the successful conservation and management of our natural resources.Key words: largemouth bass, allele, loci, polymorphism, selection, population

<em>Abstract</em>.—We evaluated long-term fisheries data relative to a range of perturbations for the Arkansas River from 1970 to 2006. Rotenone sample sites were located at pool 13 (Garrison Creek), Ozark Lake (Lavaca), and Lake Dardanelle (Panther Cove and the Arkansas Nuclear 1 Effluent Bay). The period of record was 24 years for Garrison Creek and Lavaca, 29 years for Effluent Bay, and 30 years for Panther Cove. Mean total fish biomass ranged between 466 kg/ha and 1,601 kg/ha among sites, and no temporal trends were detected for total biomass. Invasion of zebra mussels <em>Dreissena polymorpha</em>, discovery of largemouth bass virus, and imposition of a 381 mm total length (TL) minimum length limit for largemouth bass <em>Micropterus salmoides </em>likely contributed to notable changes in these fisheries during the past 30 years. Biomass of redear sunfish <em>Lepomis microlophus</em>, freshwater drum <em>Aplodinotus grunniens</em>, and blue catfish <em>Ictalurus furcatus </em>increased in association with the invasion of the river by nonnative zebra mussels. Spotted gar <em>Lepisosteus oculatus </em>and paddlefish <em>Polyodon spathula </em>biomass increased, and common carp <em>Cyprinus carpio </em>biomass declined coincident with the zebra mussel invasion. Large-scale sedimentation of aquatic habitats may have been related to observed declines of backwater-oriented species, especially common carp and spotted gar. The frequency of largemouth bass between 350 and 400 mm TL increased in electrofishing samples after the imposition of a 381-mm-TL minimum length limit, and total catch per hour of largemouth bass greater than 381 mm TL increased. Our associations would suggest that the discovery of largemouth bass virus during 2000 contributed to (1) lower electrofishing catch per hour of largemouth bass greater than 533 mm TL, and (2) an average increase of 420 h required for an angler to catch a 2.27-kg largemouth bass. We anticipate further changes in the Arkansas River during the next decade from the biological invasions of white perch <em>Morone americana</em>, bighead carp <em>Hypophthalmichthys nobilis</em>, and silver carp <em>H. molitrix</em>; increased establishment of aquatic vegetation; and accelerated loss of aquatic habitats associated with planned federal navigation channel improvements.
