Lobsters are osmoregulators

The experiment is to determine whether the six lobsters tested are osmoregulators or osmoconformers, this is done by obtaining a sample of hemolymph. The first step of the lab is to prepare the needle and syringe that will be taking the hemolymph.

Are lobsters osmoregulators or osmoconformers? | Yahoo Answers

Lobsters Are Osmoregulators Methods To determine the principals of osmoregulation, we sampled two lobsters from each tank and there were three different tanks which the water ranged in salinity.

The experiment is to determine whether the six lobsters tested are osmoregulators or osmoconformers, this is done by obtaining a sample of hemolymph. The first step of the lab is to prepare the needle and syringe that will be taking the hemolymph.

Lobsters are osmoregulators

The syringe size was 1 ml, and the intention is to collect between 0. The needle size was 20 gauge, because anything smaller would destroy the hemolymph cells. Then the lobster was picked up with a firm grim around the dorsal celphao-thorax region and flipped over to expose the ventral side.

The hemolymph was be extracted from the central midline of the ventral pre-branchial region, of the first section. Although, before piercing the membrane, the bevel of the needle had to be pointing up. When the needle was injected into the membrane, it did not have to go any deeper than mm into the hemocyannin blood cavity.A Laboratory Exercise In Osmoregulation By Bonnie Leksrisawat, Ann S.

Cooper Humans are osmoregulators as they internally monitor and regulate weight for a blue crab or a lobster is hemolymph (Gleeson and Zubkoff, ; Guirguis.

Thus, at salinities below 15 ppt it appears as though male lobsters are more efficient osmoregulators than female lobsters. 4. Discussion Lobsters and other estuarine invertebrates encounter large seasonal drops in salin- ity .

The experiment is to determine whether the six lobsters tested are osmoregulators or osmoconformers, this is done by obtaining a sample of hemolymph. The first step of the lab is to prepare the needle and syringe that will be taking the hemolymph.

Introduction and background

The syringe size was 1 ml, and the intention is to collect between and ml of hemolymph. During periods of substantial freshwater runoff, lobsters that inhabit estuaries, such as the Great Bay Estuary in NH, are exposed for several days to weeks to seawater that is diluted as low as 10 ppt.

To assess the physiological stress imposed by these conditions, we measured the oxygen consumption, heart rate, ventilation rate and hemolymph osmolarity of lobsters while sequentially exposing. Crab and lobster fishing is a commercially important business and caters to the ever increasing demand for crabs and lobsters from the food industry all over the world.

Prices of crabs vary depending on the type and size of crab.
