This thesis deals with the population characteristics of Artemia
and the effect of different environmental parameters on the different
stages of Artemia in a salina at Tuticorin, south east coast of India.
The present investigation was carried out from 1985 to I987.
The study was initiated by undertaking a survey to find out suitable
Artemia habitats along the south east coast of India and a perennial
salina with an area of 0.25 ha was selected at Karapad (Tuticorin). Weekly
samplings were made for two full calender years (1986-87) to collect
the different stages of Artemia population as well as the different
environmental parameters. The thesis comprises of the following sections: Introduction, materials and methods, systematics, biology and distribution of Artemia, results and discussion, summary and bibliography. The section on results
and discussion gives the characteristics of Artemia population in the
salina, the seasonal variations of different environmental parameters
in the salina and their effects on different stages of Artemia population.
Description of an experiment conducted to show the sudden changes of
salinity on different stages of Artemia is also given as a separate
section. |
