Description
Technical field
The present invention relates to technical field of aquaculture, specially a kind of sea-farming method of Australia freshwater lobster salinization.
Background technology
Lobster is the common name of species under Arthropoda hapalonychia guiding principle Decapoda Palinuridae.Also known as prawn, leading shrimp, shrimp chief,
Sea shrimp etc..Its cephalothorax is thicker, and shell is hard, colorful, and belly is short and small, and body is grown typically between 20~40 centimetres, weight
About 0.5 kilogram, partly it can develop into chela the day after tomorrow without chela, abdominal appendage.Most heavy can reach more than 5 kilograms, and people claims lobster brave.Body is in
Thick cylindric, back of the body abdomen slightly puts down flat, carapace prosperity, hard thick more spine, and there are a pair of powerful suproorbital spines in leading edge center, the gill for having closing
Room.
Australia freshwater lobster refers to the crayfish of Australia and surrounding area.Although there is kind more than 100, and at present in Australia
Big Leah large-scale farming and start foreign exchange earning mainly have sliding yabby to belong to three kinds.The first is Malong crayfish, someone
The bright crayfish of translations horse or wheat dragon crayfish；Second is the other crayfish of tooth, and crayfish is compared in someone's translations Asia；The third is red claw crayfish,
Also the ridge of someone's translations four slides crayfish.Therefore, Australia freshwater lobster typically now alleged by aquaculturist, just refers to commodity
