To facilitate direct comparisons between the two species of Nocomis, reproductive activities were resolved into six categories (Sabaj, 1992) that reflected the sequence of male-female interactions characteristic of a successful spawn
, its the mutation not the mutant that gives us the kicks.
This species is a multiple-batch spawner and the most active fish spawn
every day (Hirano and Yamamoto, 1992).
Sex had no significant influence on the likelihood to spawn
(Table 1), but a small proportion of males spawned
in control and phytoplankton (without sperm) treatments.

Mature gravid fishes that were ready to spawn
were observed to move slightly in ascending direction to the upper parts of the River.
Ten broods from each spawn
order were haphazardly selected.
Reproductive condition was evaluated by classifying each fish into one of four categories: undeveloped (UN; gametes not released when pressure is applied to the ventral surface of the fish); developed (DE; gonads fill the body cavity and some are released when gentle pressure is applied); spawning (SP; gametes released without the application of pressure); or post spawn
(PS; body cavity flaccid, some residual gametes may be released with watery fluid, and spawning injuries may be evident).

We examined peak spawning season recaptures of fish tagged in Newport Bay during the non-spawning season to identify if and where Newport Bay residents migrate to spawn
Wheat, rye and millet that are used in making spawn
