| Topic | Fish: Little NF Noyo Biomass for Coho vs. Steelhead, 1966-69 vs. 1992 |
| Caption: This chart shows the biomass of steelhead and coho salmon juveniles in kilograms/hectare from two different study periods on the Little North Fork Noyo River. Burns (1972) and Valentine (1994) both used electrofishing to sample extensive reaches. Burns sampled in 1966, 1968 and 1969 and the value above (Burns) represents an average of all three years. Valentine sampled only in 1992. While coho biomass seems to have decreased substantially, steelhead biomass has shown an increase.
