“…American shad Alosa sapidissima Wilson stocks have declined throughout Chesapeake Bay (U.S.A.) and its tributaries during the past century (Foerster & Reagan, 1997). The most recent declines, which have occurred since the 1970s, border on collapse.…”

Episodic increases in temperature of d5 C above 20 C, over 48 h or declines in pH of 1·0 unit from pH 7·0 reduced survival of yolk-sac and feeding-stage larvae of American shad Alosa sapidissima. Over 16 days all measures of survival, growth, and production were more favourable at each higher temperature in the 15-25 C range. More favourable responses were also obtained at the higher prey level (500 v. 50 Artemia nauplii l 1 ) and at the higher pH (7·5 v. 6·5). Combinations of high temperature and high prey levels, at pH 7·5, led to highest larval production. Little growth or production occurred at 15 C, regardless of pH or prey level. The effect of pH was strong with respect to survival, but weak with respect to growth. In attempts to restore American shad populations by larval stocking, release times and sites can be critical to optimize survival and eventual returns. Releases of larvae potentially will be most effective when made at temperatures >20 C, pH>7·0, and prey levels >50 l 1 . These conditions are most likely to occur in Maryland tributaries of Chesapeake Bay between mid-May and early June. 1999 The Fisheries Society of the British Isles

“…In fish stocks where several age classes are present, high fishing mortality may cause changes in the size frequency distribution of the annual catch (Russell, 1942;Thomson, 1959~;Foerster & Reagan, 1977). The mean size (weight) of yellowfin bream taken by anglers at Jumpinpin and Caloundra has remained relatively constant during the period 1945 to 1980.…”

Yellowfin bream, Acanthopagrus austrah, support an important angling fishery in Moreton Bay, a large estuarine system on the east coast of Australia. An analysis of the records of catches by anglers indicates that abundance and mean size of yellowfin bream have changed little in Moreton Bay during the period 1945 to 1980. Over the past 5 years substantial increases have occurred in the total angling effort for yellowfin bream at surf bar spawning areas in Moreton Bay. This has resulted in a decrease in mean catch per unit effort but no apparent decrease in total yield. Reclamation and development projects which cause degradation of the surf bar spawning areas have the greatest potential to cause reduction in abundance of yellowfin bream in Moreton Bay.
