Four genetically distinct stocks of age 2+ years largemouth bass Micropterus salmoides were produced using adults collected from two regions in the upper midwest (central Illinois, IL and south-eastern Wisconsin, WI, U.S.A.). Two pure stocks (IL IL and WI WI), as well as both of their reciprocal F 1 interstock hybrids (IL WI and WI IL) were produced in research ponds in Champaign, IL. In general, swimming performance, routine oxygen consumption and activity were highest at 18 C, intermediate at 12 C, and lowest at 6 C for all stocks. However, performance indicators varied among stocks at each of the temperatures. The pure Illinois stock (IL IL) had the lowest activity : cost ratio at 18 C and the highest at 6 C (based upon swimming strength, routine activity rates and routine metabolic rates). The opposite pattern was observed for the other pure stock (WI WI). Although differences were less distinct at lower temperatures, the two pure stocks (IL IL and WI WI) outperformed both interstock hybrids. These results indicate that not only do non-native stocks appear to have reduced performance relative to locally adapted stocks, but also that interstock hybrids exhibit performance impairments, not hybrid vigour. 2001 The Fisheries Society of the British Isles

“…Electrophoretic techniques present a means of examining genetic variation in natural populations, and have been used to corroborate subspecific status in a wide range of teleost species (Scholl, 1973;Avise & Smith, 1977;Buth & Burr, 1978;Stoneking et aL, 1981;Philipp et al, 1983) and in particular in the situation referred to above (Galleguillos & Ward, 1982).…”

Samples from two populations of the gobiid fish species Pomatoschistus minutus (Pallas) were compared electrophoretically over 31 protein loci. The population from the Lagoon of Venice was shown to possess an extra LDH staining region, not present in P. minutus from Wales or any other congeneric population. ]'he manifestation of this additional 1,DH band is strongly suggestive of a distinct genetic locus. ]he two populations have a relatively low overall 1 value even if this disparity in LDH is neglected. This is largely a re'sult of virtually complete differentiation at two other Ldh loci. It is suggested that the large contribution by 3 out of the 4 Ldh loci to population differentiation, may indicate a specific adaptive response by the Venetian population to the unusual conditions of its habitat.

“…However, larvae of unionid bivalves are parasitic on fish, and extended dispersal ability is therefore expected. One comparable allozyme study in freshwater fish did not show clear allele frequency differences between fish in the Ochlockonee River system and those in other river systems in the southeastern United States (Philipp, Childers & Whitt, 1983). For complete revision and phylogeny of the V. georgianus species complex, populations from the entire distribution and congeners need to be examined.…”

Genetic and morphological variation was studied in a brooding (ovoviviparous) and morphologically variable freshwater snail [ Viviparus georgianus (Lea)] species complex in southern Georgia and Florida. Eleven populations were clustered into three genetically isolated, allopatric groups characterized by 7 to 14 diagnostic loci out of the 38 loci examined. These allopatric groups were identified as V. georgianus (in eastern and southern Florida), V. limi (in the Ochlockonee River) and V. goodrichi (in the Florida panhandle). Nei's standard genetic distances between the species were large (0.23-0.52) compared to intraspecific distances (O.OCr0.06). Hierarchical F-statistics for differentiation among sites within drainage systems (FsD) for V. goodrichi and V. georgianus were large (0.519 and 0.387, respectively). The F,., values (differentiation among drainage systems within the total area sampled) were negative or close to zero, so most of the intraspecific genetic differentiation was due to differences among populations within drianage systems, rather than to differences among systems. Canonical discriminant analysis of nine shell morphological measurements separated all three species with little overlap. Principal components analysis of the shell morphology revealed intraspecific variation among sites possibly due to environmental effects. This study demonstrates the marked genetic and morphological variation among and within drainage systems in freshwater prosobranchs.
