A total of 1,100 gallons of liquid synergized rotenone (Pro-Noxfish) was used to establish a toxicity of 1.5 p.p.m....
The distribution and trophic ecology of neritic reef fishes was
studied to provide biological information useful in conserving these
stocks. Houk and line fishing was conducted from July 1976 to July
1977 on neritic reefs within 5 km of the Oregon coast adjacent to
Depoe Bay. Sampling was designed to...
