Effects of suspended sediment on eggs and larvae of lingcod (Ophidon elongatus), Pacific herring (Clupea harengus pallasi), and surf smelt (Hypomesus pretiosus)

Fertilized eggs and newly hatched larvae of lingcod (Ophiodon elongatus). Pacific herring; (Clupea harenqus pallasi). and surf smelt (Hvpomesus pretiosus) were exposed to different concentrations of a contaminated (False Creek) and relatively uncontaminated (Roberts Bank) marine sediment. Each bioassay test was conducted with the sediments in suspension. Effects measured included egg mortality during development, timing of development, percent hatchability, and larval survival after hatching.
