Biological assessment of Tecate Creek (U.S.-Mexico) with special regard to self-purification.
Apr 01, 2005; ... Abstract.--Macroinvertebrate organisms were sampled at four sites on Tecate Creek (U.S.-Mexico) and quantitatively evaluated using the SIGNAL-w (Stream Invertebrate Grade Number--Average Level-weighted) index. A morphological assessment of the stream structure was also carried out ....
Age and growth of spotted sand bass, paralabrax maculatofasciatus, in Bahia de Los Angeles, Baja California, Mexico, with age validation using Otolith edge analysis.
Apr 01, 2005; ... Abstract.--Spotted sand bass, Paralabrax maculatofasciatus, were collected from Bahia de Los Angeles, Baja California, Mexico covering as wide a size range as possible over four seasons (spring, summer, fall, and winter).

Feeding Ecology of Salton Sea Tilapia (Oreochromis spp.).
Apr 01, 2005; ... Abstract.--We investigated the feeding ecology of tilapia (Oreochromis spp) in the Salton Sea. Stomachs and intestines were sampled at each season. Fish foraged at the surface during the summer when dissolved oxygen was low. The proportion of plant materials in fish stomachs was higher at ...
