“…Maximal weight-specific growth rates for young (0-28 d) juvenile striped bass range from 0.12 to 0.2 d Ϫ1 depending on latitude of the source population and temperature (Conover et al 1997). For the high-growth scenario, we adopted 0.15 d Ϫ1 because it is typical of maximal growth rates for striped bass larvae and juveniles in low-midtemperate waters at 20-25ЊC (Conover et al 1997;Brown et al 1998). For the low-growth scenario, we arbitrarily chose a rate ⅓ of the high-growth scenario.…”

Estimates of the assimilation and retention of trace elements from food by fish are useful for linking toxicity with the biogeochemical cycling of these elements through aquatic food webs. Here we use pulse-chase radiotracer techniques to estimate the assimilation and retention of Se and four trace metals, Ag, Am, Zn, and Cd, by 43-and 88-d-old juvenile striped bass, Morone saxatilis, from crustacean food. Brine shrimp nauplii, Artemia franciscana, or adult copepods, Acartia tonsa, were fed radiolabeled diatoms and then fed to juvenile striped bass. Assimilation efficiencies (AEs Ϯ SD) for 43-d-old fish were 18 Ϯ 2%, 6 Ϯ 1%, 23 Ϯ 4%, 33 Ϯ 3%, and 23 Ϯ 2% for Ag, Am, Cd, Se, and Zn, respectively. For 88-d-old fish, the AEs were 28 Ϯ 1%, 42 Ϯ 5%, and 40 Ϯ 5% for Cd, Se, and Zn, respectively. The higher AEs in the older fish may result from longer gut passage times for larger fish. The 44-d-old fish excreted 5 Ϯ 0.8%, 4 Ϯ 2.0%, 7 Ϯ 0.3%, 9 Ϯ 0.4%, and 1.3 Ϯ 0.9% of the Ag, Am, Cd, Se, and Zn, respectively, they ingested from food per day, whereas the 88-d-old fish excreted 3 Ϯ 1.0%, 8 Ϯ 0.5%, and 3 Ϯ 0.5% of the assimilated Cd, Se, and Zn per day, respectively. Predictions of steady state Se concentrations in juvenile striped bass tissues made using a biokinetic model and the measured AE and efflux rates ranged from

“…Most studies focussing on latitudinal growth responses used distinct populations or strains generally separated by large geographic distances (Conover & Present, 1990;Power & McKinley, 1997;Brown et al, 1998). The present study focussed on sites where the geographic separation and latitudinal differences between adjacent sections was relatively small (Fig.…”

“…Because there can be a large thermal gradient from higher to lower latitudes within the geographic range of any species, there is a potential for differences in growth rates among populations. Several studies have made comparisons of physiological responses, including growth rates, to latitudinal variation on fishes and other aquatic organisms (Conover & Present, 1990;Mina, 1992;Conover & Schultz, 1995;Gudkov, 1996;Schultz et al, 1996;Conover et al, 1997;Parsons, 1997;Brown et al, 1998). Some of these studies suggest that fishes obtain larger sizes in lower latitudes (Carlander, 1969(Carlander, , 1977Modde & Scalet, 1985), with the idea that these areas provide more opportunity for growth due to longer growing seasons.…”

Growth rate responses of Missouri and Lower Yellowstone River fishes to a latitudinal gradient

Notropis atherinoides, freshwater drums Aplodinotus grunniens, river carpsuckers Carpiodes carpio and saugers Stizostedion canadense collected in 1996-1998 from nine river sections of the Missouri and lower Yellowstone rivers at two life-stages (young-of-the-year and age 1+ years) were significantly different among sections. However, they showed no river-wide latitudinal trend except for age 1+ years emerald shiners that did show a weak negative relation between growth and both latitude and length of growing season. The results suggest growth rates of fishes along the Missouri River system are complex and could be of significance in the management and conservation of fish communities in this altered system.

“…Both parental stocks have widespread natural distributions in eastern North America but appear to show limited morphological variation (Waldman et al 1988, Waldman andWirgin 1995). However, some northern strains of striped bass fry grow faster than fry from southern strains (Brown 1994, Brown et al 1998. That gradient was not evident when Jacobs et al (1999) evaluated 19 other families for growth rate and found Maryland and Florida strains grew faster than South Carolina and New York strains.…”

Sunshine Bass Fingerling Culture

Year-round production is a top priority of hybrid striped bass producers. Most Morone culturists produce sunshine bass (white bass Cf X striped bass d') that have very tiny fry and require rotifers as their first food. Almost 100 percent of the fingerlings are produced in ponds where high survival rates depend on fry being stocked at the right time -before rotifer concentrations peak and before copepods appear. Pond culture drawbacks include the inability to monitor growth and survival and seasonal limitations due to weather. Tank culture overcomes these problems and is necessary for year-round production. Little tank fingerling production has occurred because costs are higher than for pond culture. Supplying live food is a major expense. Sunshine bass larvae are stocked at 4 to 5 days post hatch (dph) and are fed enriched cultured rotifers. The rotifers require microalgae. Within a few days the fry are weaned to cultured Artemia nauplii. The culture of the larger palmetto bass and striped bass starts with feeding Artemia nauplii. By about 15 dph, weaning to an artificial diet begins and is completed by 26 dph. Grading at that time reduces cannibalism. Live food culture is risky, and requires time, space, costs, and expertise. Recent innovations may alleviate some of these problems. High-density (up to 16,000/mL) rotifer production methods are being developed. These systems require constant feeding, oxygen, pH and ammonia control, suspended particle removal, and proper harvesting. Fatty-acid enriched algae pastes can replace cultured algae. Ammonia and pH problems can be controlled with products like Chloram-X® and auto-sensing pH controllers. Water is conserved by utilizing recirculation systems for rotifer and fingerling production. Use of commercially available decapsulated brine shrimp eggs further reduces time and physical risk. Increased demand for fingerlings during the winter and reduced culture costs will increase tank fingerling production. INTRODUCTIONYear-round production of sunshine bass is a top priority of hybrid striped bass producers (Anonymous 1998). Currently, fry and fingerling production is confined to March through June, the normal spawning periods of the parental stocks (Mike Freeze, Keo Fish Farm, personal communication; Becker 1983). Fish reach market-size in 10 to 20 months after hatching, depending on stocking rates, culture conditions, and diet (Carlberg et al. 1989). As a result, it is difficult for fish farmers to provide hybrid striped bass of uniform size and quality to markets yearround. Consequently, prices also vary considerably during the year. It is important to develop culture techniques that will provide for year-round availability of sunshine bass fingerlings.The culture of striped bass (Marone saxatilis) and its hybrids with white bass (M. chrysops) for the food-fish market is a recent endeavor. The initial incentive for Marone culture was to replenish wild populations of striped bass whose stocks had been depleted by over-fishing and habitat degradation. However, hybrid...
