“…The longest larvae were obtained at 14°C and 5 %o salinity. Temperatures of 12°C are reportedly near the lethal levels (Hall, 1991). Doroshev (1970) reported 10°C to be lethal to larvae, with optimal survival at 15-19°C.…”

“…Hall (1991), in a review of available data, reported salinities of 0-15 %o suitable for larval survival. The estimated values of yolk and oil reserves present at hatch (72 and 80 I~g, respectively) are similar to the mean values reported by Eldridge et al (1982), of 60 and 130 Ixg, respectively, and within the range of values reported from several egg batches.…”

“…This paper investigates the influence of two environmental variables, temperature and salinity, on the yolk utilization phase of striped bass larvae. Generally speaking, striped bass yolk-sac larvae have been found to survive best at temperatures of 15-20°C and salinities of 1-5 %o (Albrecht, 1964;Doroshev, 1970;Lal et al, 1977;Morgan et al, 1981;Hall, 1991). Two questions are addressed: how do temperature and salinity affect yolk utilization and larval size; and how do several parameters of larval development, such as maximal larval length, relate to generally accepted times to first feeding?…”

The effects of temperature and salinity on yolk utilization and growth of larval striped bass (Morone saxatilis) from Canadian maritime stocks were studied to determine optimal rearing conditions. Larval length increased during yolk utilization and maximum length (Lm~) was attained at about 70 degree-days post-hatch. Dry weight declined during yolk utilization, whereas, larval wet weight was relatively constant and only declined when yolk was depleted. Temperature and salinity significantly affected the Lm~. Temperatures exceeding 18°C resulted in lower Lm~ x. Higher Lma x values were attained at 5 %o than at 1 or 10 %°. Time to reach Lm~ was longer at 5 and 10 %0 than at 1%o for any experimental temperature. Time to reach Lm~ was 3 days post-hatch longer than times to maximum embryo dry weight. The Q10 of yolk utilization was 1.71, 1.53 and 2.52 at 1, 5 and 10 %o, respectively. Times to terminal yolk utilization were about 1.2 d shorter than times to Lm~ x. Morphological changes during yolk utilization indicated rapid development of locomotory and predatory capabilities. These and other developmental strategies were compared to those of salmonids. Rearing striped bass larvae at 14-16°C and 5 %0 throughout yolk utilization should result in longer larvae at initial first feeding.

“…Seining surveys for juvenile striped bass by the Maryland Department of Natural Resources indicated that declines probably are the result of poor survival during the first 60 d of life (Boone 1980). Many potential causes for population declines of Chesapeake striped bass have been proposed and studied, including overfishing (Goodyear 1985), disease, pollution (Hall et al 1985, Westin et al 1985, Hall 1991, acid precipitation, starvation (Martin et al 1985), predation (McGovern & Olney 1988) and habitat loss, alteration or deterioration (Coutant 1985, Price et al 1985, Coutant & Benson 1990. Some hypotheses have been tested and discounted a s major causes of the declines while others are difficult to test directly.…”

ABSTRACT. A StellaTM lnodel based on laboratory-derived growth data was developed to simulate abundances, cohort survival and growth rates of striped bass eggs and larvae. The goal was to compare the simulations to 1987 field survey results from the Potomac River (Cheasapeake Bay, USA). Key factors in the model were striped bass egg production, water temperature, surface light and penetration, turbidity and zooplankton concentration. Growth and survival were simulated from the predicted effects of turbidity. light at depth, and zooplankton concentration. Predation terms simulated survival under different predation pressures. The model estimated dally ~nstantaneous growth rates ranging from -0.07 to 0.19 d -' The model predicted poor survival and growth of cohorts produced early in the spawning season when water temperatures and zooplankton concentration were low. Mortality of eggs was predicted to be 54 % by simulation with most of the mortality att~ibutable to low temperatures early in the spawning season. Simulated growth rates ranged widely and were highest in the down river sections of the Potomac. Predicted groxvth was in close agreement with field estimates during the second half of the spawning season. Early in the season, field growth rates were higher than those modeled, possibly because survival was more growth-rate dependent a t that time than later when temperature, light a n d food levels were nearer to optimum. Trends in simulated larval abundances resembled Potomac River estimates but there were differences in simulated peak abundances. Mortality was partitioned and attributed to causes other than that caused by low temperature anomalies and growth-dependent factors. The difference between modeled and field observed larval abundances estimated a rate of mortality for 'other' causes at 13.7 ";I d-', a rate that can readily be attributed to predation.

“…Dechlorination will remove chlorine toxicity and will considerably reduce the potential for by-product formation. However, studies investigating the toxicity of chlorinateddechlorinated seawater observed increased mortality [206,207] and chronic effects [208] of test species even in dechlorinated seawater. The observed effects were assumed to be due to the presence of halogenated organics formed during chlorination.…”
