I investigated the influence of food availability on growth and survival of walleye (Stizostedion vitreum vitreum) fry stocked in six fertilized experimental ponds (density 40 fish∙m−3) and reared for 8 wk. Walleye fed largely on chironomid larvae and cyclopoid copepods in weeks 1 and 2, and chironomids thereafter. Prey choice and consumption were strongly influenced by chironomid biomass in the benthos, and to a lesser extent by zoo-plankton density. Weekly length increase of the populations and mean length in week 7 were significantly correlated with chironomid benthic biomass and mean prey length. Chironomid biomass and density of large zoo-plankton together explained 56% of the variation in the weekly population growth rate. Despite obvious food limitation in the second half of the experiment, pond survival rate was not significantly correlated with mean prey density, mean stomach fullness, or percentage of fish with empty stomachs. The results indicate that juvenile walleye growth can be regulated by the density and size of available prey. Prey availability apparently does not regulate short term juvenile walleye survival rates after the period around first feeding.

Effect Of Light

This study investigates the influence of light intensity on feeding of striped trumpeter larvae, correlating feeding responses with changes in morphology of the retina during growth. A pigmented single-cone retina had differentiated one day before first feeding, and rod precursor cells and double cones were visible in the retina on the 23rd, and 25th day after hatching, respectively. Feeding performance at four light intensities (0, 1, 30, 150 and 700 lux), revealed that striped trumpeter larvae are primarily dependent on vision, a light-dependent behaviour, to feed. The youngest larvae tested (15, 18 and 19 days of age) showed a poor feeding response at 1 lux (range 2–10%), but a 98–100% feeding response at 30, 50 and 700 lux. By 28 days of age, feeding behaviour had changed significantly, with 52% of fish now feeding at 1 lux, 100% of fish feeding at the intermediate light intensities of 30 and 150 lux, and only 62% of fish feeding at 700 lux. The apparent increased photopic sensitivity in 28-day-old fish may reflect increased areas for photon capture provided by double cones, or may reflect ontogenetic changes in cone spectral sensitivity.
