“…Although bait bucket transfer has long been suspected (Ludwig and Leitch 1996), viable diapausing eggs create another wrinkle. Because of this feature, baitfish provide a simple vector for movement of eggs from one lake to another (Jarnagin et al 2000;Compton and Kerfoot 2004).…”

Temperature, recreational fishing and diapause egg connections: dispersal of spiny water fleas (Bythotrephes longimanus)

The spiny water flea (Bythotrephes longimanus) is spreading from Great Lakes coastal waters into northern inland lakes within a northern temperature-defined latitudinal band. Colonization of Great Lakes coastal embayments is assisted by winds and seiche surges, yet rapid inland expansion across the northern states comes through an overland process. The lack of invasions at Isle Royale National Park contrasts with rapid expansion on the nearby Keweenaw Peninsula. Both regions have comparable geology, lake density, and fauna, but differ in recreational fishing boat access, visitation, and containment measures. Tail spines protect Bythotrephes against young of the year, but not larger fish, yet the unusual thick-shelled diapausing eggs can pass through fish guts in viable condition. Sediment traps illustrate how fish spread diapausing eggs across lakes in fecal pellets. Trillions of diapausing eggs are produced per year in Lake Michigan and billions per year in Lake Michigamme, a large inland lake. Dispersal by recreational fishing is linked to use of baitfish, diapausing eggs defecated into live wells and bait buckets, and Bythothephes snagged on fishing line, anchor ropes, and minnow seines. Relatively simple measures, such as on-site rinsing of live wells, restricting transfer of certain baitfish species, or holding baitfish for 24 h (defecation period), should greatly reduce dispersal.

“…Vectors of rusty crayfish introduction include bait bucket discharge from recreational anglers (Ludwig and Leitch 1996) and intentional releases by lake-users for nuisance weed control (Magnuson et al 1975) and commercial crayfish retailers (Gunderson 1999). Support for these mechanisms comes from Capelli and Magnuson (1983) who found that human activity and lack of geographic isolation were the best predictors of rusty crayfish occurrence in lakes of northern Wisconsin.…”

The rapid spread of rusty crayfish (Orconectes rusticus) with observations on native crayfish declines in Wisconsin (U.S.A.) over the past 130 years

The rusty crayfish, Orconectes rusticus, is one of America's best-known non-indigenous crayfishes, having been identified as extirpating native crayfishes and disrupting local aquatic ecosystems. Over the past 40-50 years, rusty crayfish have spread from its historical range in the Ohio River drainage (U.S.A.), to waters throughout much of Illinois, Michigan, Wisconsin, and Minnesota and parts of 11 other states, Ontario (Canada) and the Laurentian Great Lakes. Using a comprehensive dataset based on all known historical records and extensive present-day surveys (n=2,775) this study reports on the invasion history of rusty crayfish, with observations on concomitant declines of native crayfishes in Wisconsin over the past 130 years . We found that rusty crayfish occurrences have increased from 7% of all crayfish records collected during the first 20 years of their invasion (1965)(1966)(1967)(1968)(1969)(1970)(1971)(1972)(1973)(1974)(1975)(1976)(1977)(1978)(1979)(1980)(1981)(1982)(1983)(1984) to 36% of all records during the last 20 years, and that rusty crayfish have replaced the northern clearwater crayfish (O. propinquus) and virile crayfish (O. virilis) as the most dominant member of the contemporary crayfish fauna. In light of our results we discuss the introduction, establishment and integration phases of the rusty crayfish invasion and provide preliminary predictions of the potential distribution of rusty crayfish in Wisconsin lakes based on critical environmental requirements.

“…So-called bait fish such as spottail shiners (60-90 mm) are known to consume Bythotrephes in large numbers (Hartman et al 1992;Compton and Kerfoot in press). Ludwig and Leitch (1996) and Jarnagin et al (2000) suggested interbasin transfer of biota via anglers' bait buckets. Diapausing eggs could be dispersed by fish or in live wells, as anglers travel between lakes in the watershed.…”

Zooplankton demographics operate over multiple time scales corresponding to pelagic parthenogenetic generations, an overwintering stage, and an ''egg bank.'' Comparisons of pelagic birth and death rates with seasonal diapausing egg production provide insights into local species persistence. The spiny cladoceran (Bythotrephes) possesses morphological adaptations (spines and thick-walled diapausing eggs) that lessen, but do not eliminate, predation effects by fish. Because caudal spines are retained throughout life and are indigestible in fish guts, spine accumulation in sediment traps directly documents patterns of seasonal mortality. Here, we contrast deposition of spines and diapausing eggs in a recently colonized inland lake (Lake Michigamme) with deposition in a larger source lake (Lake Michigan). Direct mortality estimates at the inland lake correspond well with traditional indirect estimates from egg ratio techniques. Although spines are effective against abundant small fish in the inland lake, individuals are susceptible to ingestion by late-season young of year and larger fish. Laboratory experiments confirm that fish are responsible for spine breakage in the water column, accounting for an estimated 62-71% of seasonal mortality. Effects of late-season predation are lessened because diapausing eggs survive gut passage, yet yearly production of diapausing eggs is low in Lake Michigamme. A more balanced pelagic birth(death) to diapausing egg relationship exists in Lake Michigan, probably because egg-carrying adults find better refuge in central, deeper waters. Since spines catch on seines and diapausing eggs survive gut passage, use of bait fish and live wells promotes Bythotrephes dispersal.Zooplankton studies in lakes traditionally concentrate on seasonal pelagic dynamics of local populations (N p ; Fig. 1). Yearly population growth is treated as the consequence of a dynamic balance between instantaneous birth (b) and death (d) rates (r ϭ b Ϫ d). Netting of plankton allows seasonal estimates of brood sizes and population density. Temperature-dependent regressions for developmental duration convert egg ratio measures into instantaneous birth rates (b), whereas changes in pelagic population size allow independent estimates of the realized population growth rate (r). The difference between the instantaneous birth rate and the re-1
