GROWTH-RATES OF PERINEREIS-RULLIERI (POLYCHAETA, NEREIDIDAE) UNDER DIFFERENT CONDITIONS OF TEMPERATURE AND DIET

The effects of temperature and diet on growth rates of the nereidid polychaete Perinereis rullieri have been investigated under controlled laboratory conditions from the beginning of larval feeding. Growth rate was evaluated under three diets (filamentous green algae, nauplii of Artemia salina, and Tetramin MikroMin dry fish-food), and three temperatures (15-degrees-C, 21-degrees-C, and 27-degrees-C). Growth rate was influenced both by diet and temperature. Diet appears the main factor strongly modifying the growth pattern.
