has been intensified. One of the problems that causes low survival in the larval rearing of mud crab is the occurrence of bacterial and fungal infection. Treflan‚ a fungicide‚ has been used to prevent the occurrence of fungal infection in some crustaceans. However‚ the effect of Treflan on the growth and survival of each larval stage of mud crab has not been investigated. This research about on crabs was conducted because of two reasons. One was to determine the effect of various concentrations

Arthropoda The phylum Arthropoda‚ being the largest phylum in all of the kingdom Animalia‚ makes up about 84% of all known animal species. From tiny terrestrial insects to the aquatic king crab equipped with a 12 foot arm span‚ arthropods are evident in every habitat on Earth. Despite the diversified phylum‚ all members share a basic body structure containing a jointed skeletal covering with jointed appendages. An arthropod’s unique jointed exoskeleton provides support as well as locomotion

Crayfish are close relatives of the Lobster and resemble a small shrimp. They live in freshwater habitats in North America and Europe. The Crayfish has a joined head‚ thorax‚ and a segmented body. They range in colors for yellow‚ green‚ red‚ and brown. Crayfish are around 3 inches long. The Crayfish has two pairs of sensory antennae. The eyes are all long pieces of skin that allow the eyes to move. The appendages of the thorax have four pairs of walking legs which are also used to help find

Animal Behavior in Isopods based on Climate‚ Light‚ and Surface Abstract Pill bugs‚ (also named sow or potato bugs) are terrestrial crustaceans that consume decomposed leaves or other plants. In the lab performed on September 24‚ 2010‚ animal behavior of the isopods was recorded‚ specifically in the climate that they preferred. Various climates situations such as Light vs. Dark‚ Hot vs. Cold‚ and Wet vs. Dry were tested and observed. The results came back with the pill bugs favoring dark‚ wet

fish flakes. About once a month you can offer a little treat such a cabbage leaf‚ a lettuce leaf or a piece of banana or mango. Digestion and Excretion Hermit crabs eat with their chelipeds (a pincerlike structure on the end of a limb of a crustacean‚ that resembles a claw) and small mouth parts. The food is passed into their mouth to the gut. Waste products are excreted as urine through antennal glands at the base of their antennae or solid waste pass out through the anus. Habitat Strawberry

Pill bugs are knows as woodlice‚sowbugs‚ and roly-polies.Despite the name Pill bugs aren’t actually “bugs” they are classified as terrestrial isopods and fall under the class Crustacea.This class also falls under an even larger group called Arthropoda. Arthropoda consists of many Arthropods that have bilateral symmetry‚segmented bodies‚exoskeletons‚jointed appendages‚and numerous pairs of limbs.Pill bugs also have a flattened or round-backed profile‚seven pairs of legs‚ and sharply-angled antennae

The aim of this investigation was to determine which component wavelength of light functioned best in a brine shrimp’s phototaxic and photokinetic responses. It was hypothesised that the brine shrimp would display a heightened positive phototaxic response‚ and that a more pronounced photokinetic response (increased velocity) would be observed when the samples were exposed to green light. Artemia salina (common name: Brine Shrimp)‚ are from the order Anostraca of the class Crustacea. Adult brine
