The effect of MS 222 for inducing anaesthesia in 60 P. radiata was studied under different concentration and various stimulating factors. Based on the results of mortality rate, induction time, duration of anaesthesia, recovery time, responses of the organism to the ansthetic and handling , it was concluded that the concentration of 1ppt of MS 222 was the best for indiucing anaesthesia, in P. radiata......

Octadecyl - bonded silica membrane disk was evaluated for extraction of surfactants from water. Different parameters such as extraction efficiency, maximum capacity of the disk, proper eluent for washing the sutfactents from the disk and effect of vacium pressure on percent recoveries were studied. Results showed that more than 95 percent of surfactants were extracted easily from water, Maximum capacity of the disk was about 5 mg. Also it was determined that this technique compareto liquied liquied extraction would introduce less error in analytical results......

If a piece of life tissue of a person is grafted to another person, after a short period the transplanted tissue will be disintegrated and disappear. Also in most infectious diseases , the victim will be resistant against the malady after recovery. Such body responses are are called Immunological reactions and the study of these reactions, mechanisms involved and related consequences is known as Irnmunology. Of the most important applications of Immunology are disease prophilaxy (through vaccination), diagnosis and treatment......

One of the major problems of pearl oyster cage culture in the persian Gulf is boring and fouling organisms attacking oyster under culture, The infected oyster lose thier commerical longevity, heathy resulting in a decrease in pearl production capability. P. margaritifera is one of the rarest species of pearl oysters in the persian Gull. As such much research arr now being undertaken to study the parasites and thier relationship with host organism in an eftort to protect it's stocks. Cliona sp. has been found to he the most Common parasite, causing much destruction to the oysters. In this article the extent of oysters infested with this parasite and subsequent destruction of oyster shells is described......

The effect of Adrenaline on Acid phosphatase activity in the gonadal extract of C. cucullata at different time intervals (10, 20, 30 minutes) and adrenaline concentrations (0,.074, 0.74, 7.4. 74 Rgrn1-1) was studied. The results showed that there is highly significant ccarrelation between time intervals (IV)1 and acid phosphate activity (DV)2 at different adrenaline concentrations (P < 0_05 r > 0.999). Aditionally, no significant correlation was detected between adrenaline concentration (IV) and acid phosphatase activity (DV) at different time intervals (F> 0,2. , r> 05)......

This is the first report on the C. capoeta infestation with C. complanatum. 112 fish sampled and surveyed for the likely infection with C. complanatum. Using the length group, extent of contamination, sex, infected organs and number of parasites in each organ, various graphs prepared. It was concluded that female Fish were the most infected with decreasing precent of infestation as the body length increased.Gill cavity and pharynx were demonstrated to be the main contaminated areas and ten parasite per fish was the greatest number recorded. Contaminated organs were subject to pathologycal studies. Since birds are the end host sepearted metacer cares were fed to 15 chicks and their maturity stages was investigated at different time intervals in contominated organs. The parasites were mature after three days......
