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.

Purpose

The purpose of the present study was to extend the information generated through the 1982 study to the eggs and larvae of three other marine fish species of local commercial importance, viz. lingcod (Ophiodon elongatus), Pacific herring (Clupea harengus pallasi), and surf smelt (Hypomesus pretiosus). These species spawn in proximity to the Point Grey and Victoria Ocean Dumpsites. Bioassay tests using eggs and larvae of each species were conducted to investigate the toxic effects of contaminated and uncontaminated sediment suspensions upon hatching success, timing of development, and larval survival after hatching. Based on these data, recommendations are made regarding the use of toxicity testing with early life history stages of marine fish species to determine the quality of dredged spoils designated for ocean dumping.
