The Effect of Temperature on the Hatching Success of Brine Shrimps
Title of Experiment: The Effect of Temperature on the Hatching Success of Brine Shrimps.
Abstract
In this experiment, 40 brine shrimp eggs are put into a test tube containing salt water at different temperature such as 25°C and 35°C respectively. The eggs are left from two days to hatch. After two days, the number of eggs successfully hatched are observed and counted.
Introduction
Brine shrimp is the common name for a primordial crustacean that reaches less than 1.3 cm in length and is usually used as fish food in aquariums. Brine shrimp can be found almost everywhere in the world in inland saltwater. Although brine shrimp are considered to be members of a single genus, Artemis, and possibly a single species, there are a number of varieties. Brine shrimp are classified in the phylum Arthropoda , subphylum Crustacea, class Branchiopoda, order Anostraca. Generally, they have stalked compound eyes and tapered bodies with a trunk that bears 11 pairs of legs. Females have a brood pouch where the young are released under favourable conditions. Otherwise eggs are laid parthenogenetically and eggs the can be dried and remain viable for many years. These eggs are extremely resistant to unfavourable environmental conditions. Brine shrimps are used for fish food. On the the hand, adult brine shrimp are also used as food in aquariums and are generally sold frozen. Figure 1: Brine shrimp
Brine shrimps are categorised as a “rapid-cycling” animal. These simply carry the meaning that these organisms grow and complete their life cycles quickly. They grow quickly - within 24 hours and mature in 3 months time. Due to these special features, this animal is very ideal for this biology experiment. Once placed in water, the cyst-like eggs hatch within a few hours. The nauplii, or larvae, are less than 0.5mm in length when they first hatch. Brine shrimp have a biological life cycle of one year, during which they grow to a mature length of around one cm on average. This
