| isolation and characterization of potentially toxic or harmful cyanobacteria from oaxaca and chiapas, mexico. | the toxic effects of 7 coastal cyanobacterial strains isolated from oaxaca and chiapas, mexico were evaluated. growth was determined by dry weight. toxicity bioassays were done in artemia sp., juvenile white shrimp litopenaeus vannamei and mice mus musculus (icr strain). in shrimp, three feeding methods were implemented: cyanobacterial biomass plus commercial food, cyanobacteria only, and biomass at different concentrations (18, 9, 4.5 and 2.2% w/v). in artemia sp., limnothrix amphigranulata (li ... | 2010 | 20390852 |
| [composition by size, age and growth of litopenaeus vannamei (natantia: penaeidae), in mar neutro lagoon, oaxaca-chiapas, mexico]. | the commercial catches of white shrimp litopenaeus vannamei were sampled (may through november 1996) in the mar muerto lagoon located between oaxaca and chiapas states, mexico. to measure it's growth rate at the innermost portions of this system, 16,378 length and weight records were obtained. length fluctuated between 11 and 145 mm, and weights between 0.1 and 26.3 g. the minimum mean size for recruitment to the exploited phase is 45 mm. organisms leave the lagunar system for recruitment to the ... | 2000 | 11487933 |
