| Summary: | ,Cumulative sampling effort yielded 2139 fishes comprised of 29 species in 15 families. Overall density of 17.8 fish/m2 Although any one month may have been characterized by a and pinfish (Lagodon rhomboides) represented 7 1 % of the and salinity (> 25 ppt) readings during summer. Seagrass Atlantic and Gulf of Mexico seagrass habitats. Individual biomass, in contrast to hydrographical conditions, exhibited density was low while species density was high (9.7 diversity were not evident. Water temperature and salinity effect of seagrass biomass on population parameters. exerted significant effects on fishes in Christmas Bay, with fall yielding peak seasonal in-plot averages. A total of 5 Fishes in Christmas Bay, TX were collected during April 1994 goby (Gobionellus boleosoma), code goby (Gobiosoma robustum), history stages of commercially and recreationally important in Christmas Bay was higher than those reported from several lowest catches concurrent with highest temperature (> 30 C) mean species/m2 varied from 2.6 (July) to 5.4 (October), with means ranged from 73.7 (summer) to 243.3 (spring) fish/month no significant effect on fish population parameters. Darter parameters and hydrographic conditions; and 3) evaluate plots yielded between 0 and 108 fish/m2; monthly mean catch provided vital nursery habitat to a diverse fish assemblage. ranged from 3.6 (July) to 31.5 (March) fish/m2. Seasonal ranged from 6.3 (winter) to 10.3 (fall). Individual sample relationship between variability in fish population sample plots yielded between 0 and 8 species while monthly seagrass habitat. Other fishes, including certain life sparse ichthyofauna, Christmas Bay seagrass beds annually species, used seagrass habitat for limited durations. species/m2). Distinct seasonal trends in biomass and species their density, biomass, and diversity; 2) define the through March 1995 to: 1) assess temporal variability in to 13 species was collected per month while seasonal averages total catch and appeared to exhibit sequential usage of with between 67 and 373 fish collected monthly.
