    Studies on the blood serum of the euryhaline cyprinodont fish, Fundulus heteroclitus, adapted to fresh or to salt water. Serum is the liquid fraction of whole blood that is collected after the blood is allowed to clot. The clot is removed by centrifugation and the resulting supernatant, designated serum, is carefully removed using a Pasteur pipette. Plasma is produced when whole blood is .

    The fish were killed after two weeks and blood was collected from the caudal artery in microhematocrit capillary tubes ac-cording to the procedure of Pickford et al. (). The blood was allowed to clot after which it was centrifuged to provide serum sam-ples. Because so little serum was available from a single fish, samples from three fish were. The purpose of the following study was to determine blood osmotic concentrations and tissue water content for these fish in the hypersaline field environments described Studies on the blood serum of the euryhaline cyprinodont fish, Fundulus heteroclitus, adapted to fresh or salt water. Trans. Con-.

      Most previous studies on euryhaline fish have focused on Serum was separated from blood cells by centrifugation ( × g for 10 min) and assayed for dopamine concentration. The present study, designed as a pilot study, indicates that A. regius could be considered as a partially euryhaline species. In this sense, freshwater resulted too much of a challenge, while a hyper-osmotic environment of 55 ppt salinity induced consumption of energy stores and fish .

Based on the results from this study, P. orbignyanus can be characterized as a marine/estuarine euryhaline teleost capable of hyper/hypo iono- and osmoregulation over the fluctuating salinity. on the blood serum of the euryhaline cyprinodont fish occurred with the mummichog in the low salinity group in this study, which may have experienced difficulty in striking a balance between.

In the trained set of fish, initial serum glucose levels were mg/ ml and showed no significant changes for as long as 5 days after the exposure to air. The peak levels of serum glucose found in the untrained fish after 6 and 12hr were significantly higher than those in the untrained fish at comparable times.

This present study would form a baseline data for assessment of health status of and E. coioidesA. latusas well as reference point for future comparative study effects of different endogenous and exogenous factors on blood biochemical of these two fish species.

Euryhaline organisms are able to adapt to a wide range of example of a euryhaline fish is the molly (Poecilia sphenops) which can live in fresh water, brackish water, or salt water.

The green crab (Carcinus maenas) is an example of a euryhaline invertebrate that can live in salt and brackish line organisms are commonly found in habitats such as estuaries and tide. The serum was frozen at The methods employed for serum chemistry are those described previously for the blood of Fundulus heteroclitus (Pickford et al., ): in brief, Na+ and K+ with the IL flame photometer, Cl- with the Aminco Cotlove chloride titrator, Cal+ colorimetrically with neutral fast red, inorganic P by the method of Fiske and.
