The effect of temperature on the hatching success of brine shrimps

OBJECTIVES

To investigate the effect of temperature on the hatching success of brine shrimps

INTRODUCTION

Despite being food for the birds, brine shrimps also help to clean up the polluted lake by ridding the water contaminated with phosphorus, nitrogen-rich compounds from fertilizers as well as other household waste products. Wild brine shrimps normally consume a species of microscopic green algae called Dunaliella by using their appendages to funnel nutrients towards their mouth. These algae are the main food source for newly hatched brine shrimps because they are small, unicellular and have a soft exterior which can be easily digested. However when Dunaliella becomes scarce, the brine shrimp will consume the larger golden brown algae even though it is difficult to digest the rigid silica cell wall of that algae. Juvenile brine shrimp cannot ingest both algae and is therefore finding other sources of food. Cultured brine shrimp can also be fed with particular foods such as yeast, wheat flour or egg yolk.
