Households Our Competitive Advantage A close study of the fish and seafood farming industry reveals that the market has become much more intensely competitive over the last decade. As a matter of fact, you have to be highly creative, customer centric and proactive if you must survive in this industry. We have done our homework and we have been able to highlight some factors that will give us competitive advantage in the marketplace; some of the factors are effective and reliable abalone farming processes that can help us sell our produce at competitive prices, good marketing network and excellent relationship management.
Prawn is often used as a synonym of shrimp for penaeoidean and caridean shrimpespecially those of large size. From the English Oxford Dictionaries: Unlike crabs and lobsters, shrimp have well developed pleopods swimmerets and slender walking legs; they are more adapted for swimming than walking.
Historically, it was the distinction between walking and swimming that formed the primary taxonomic division into the former suborders Natantia and Reptantia. Members of the Natantia shrimp in the broader sense were adapted for swimming while the Reptantia crabs, lobsters, etc. They look somewhat like small lobsters, but not like crabs.
The abdomens of crabs are small and short, whereas the abdomens of lobsters and shrimp are large and long. The lower abdomens of shrimp support pleopods which are well adapted for swimming.
The carapace of crabs are wide and flat, whereas the carapace of lobsters and shrimp are more cylindrical. The antennae of crabs are short, whereas the antennae of lobsters and shrimp are usually long, reaching more than twice the body length in some shrimp species. They look somewhat like large versions of shrimp.
Clawed lobster have large claws while spiny lobsters don't, but have instead spiny antennae and a spiny carapace. Some of the biggest decapods are lobsters.
Like crabs, lobsters have robust legs and are highly adapted for walking on the seafloor, though they do not walk sideways. Some species have rudimentary pleopods, which give them some ability to swim, and like shrimp they can lobster with their tail to escape predators, but their primary mode of locomotion is walking, not swimming.
Unlike shrimp, their abdomen is small, and they have short antennae and a short carapace that is wide and flat. They have prominent grasping claws as their front pair of limbs. Crabs are adapted for walking on the seafloor. They have robust legs and usually move about the seafloor by walking sideways.
They have pleopods, but they use them as an intromittent organ or to hold egg broods, and not for swimming. Whereas shrimp and lobsters escape predators by lobsteringcrabs cling to the seafloor and burrow into sediment. Compared to shrimp and lobsters, the carapace of crabs are particularly heavy, hard and mineralised.
The following description refers mainly to the external anatomy of the common European shrimp, Crangon crangonas a typical example of a decapod shrimp. The body of the shrimp is divided into two main parts: The shell which protects the cephalothorax is harder and thicker than the shell elsewhere on the shrimp and is called the carapace.
The carapace typically surrounds the gillsthrough which water is pumped by the action of the mouthparts. It is a rigid forward extension of the carapace and can be used for attack or defense. It may also stabilize the shrimp when it swims backward. Two bulbous eyes on stalks sit either side of the rostrum.
These are compound eyes which have panoramic vision and are very good at detecting movement. Two pairs of whiskers antennae also issue from the head. One of these pairs is very long and can be twice the length of the shrimp, while the other pair is quite short.
The antennae have sensors on them which allow the shrimp to feel where they touch, and also allow them to "smell" or "taste" things by sampling the chemicals in the water. The long antennae help the shrimp orient itself with regard to its immediate surroundings, while the short antennae help assess the suitability of prey.
The first three pairs, the maxillipedsLatin for "jaw feet", are used as mouthparts.Primary Industries and Regions SA (PIRSA) is a key economic development agency in the Government of South Australia, with responsibility for the prosperity of the state's primary industries and regions.
