    Hello, there are various types of extraction methods, the most commonly used extraction method for pharma and food grade DHA or EPA is SC CO2 (supercritical fluid extraction). This method is highly efficient in terms of quantity and quality. The pressure and temperature depends on the combination of fatty acids. Some algae contains only EPA or DHA in higher amount and some algae contains both DHA and EPA. Trials are required to find out optimum temperature/pressure for a particular algae species.

    A Similar work has been carried out by University of Perugia, Italy. Here is a link to the published paper - http://www.isasf.net/fileadmin/files/Docs/Versailles/Papers/N4.pdf. This temperature and pressure given can be used as a benchmark.
