Conocimiento control y evaluación del fitoplancton en la piscina camaronera Santa María

The knowledge, control and evaluation of phytoplankton of the shrimp pond "Santa María" located on the road to Guarumal km 13.5, Canton-Machala, El Oro Province, was monitored during the months of October-November-December, taking samples weekly at level of column of water (Surface – Middle – Bottom) at three points of the pond ( Input of Gate - Center of Pond - Output of Gate ). Additional parameters such as water pH, turbidez, salinity, oxygen, temperature were takes. The collected samples were conserveds and preserveds with formol to 5%, after was transporteds to the Laboratory of Analysis "The Acuacultor" located in Puerto Bolívar – El Oro, being analyzed qualitative and quantitatively. With the qualitative analysis the phytoplankton had greater predominance in the shrimp pond of such mode: Group of Diatomeas: Navícula brasieliensis, Navícula radiosa and Nitzchia acicularis; and Group of Cianophytas: Oscillatoria. The percentages of phytoplankton (Input of Gate - Center of Pond - Output of Gate) in the shrimp pond "Santa María" was: Diatomeas 48%, Cianophytas 41% and Clorophytas 11%. While in the quantitative analysis of the phytoplankton it was observed the following results: Input of Gate with 58 041 cells/ml, Center of Pond with 51 433 cells/ml and the Output of Gate with 64 649 cells/ml. In the percentage analysis at level of column of water was determined that in the bottom it prevailed with most high concentration of phytoplankton, representing the Diatomeas 57% in the Output gate followed by Cianophytas with 48% in the Input gate and the Clorophytas with 8% in the Center of pond and with the same value at the Output of gate. Applying descriptive statistic the design of variance analysis ANOVA of a road was used with three treatments by means of the test from Tukey-Kramer at p 0, 05 to establish the variance in the increments of phytoplankton among the referred points, giving as result that there exist not significant difference between the means.
