EFFECT OF PH ON THE RESPIRATION

The pH value of this research report on freshwater bivalves

Mollusks, Indonaia cyan from Pima River, Pandharpur nearby. Freshwater

Mollusks are considered aquatic ecosystems most important component. This is

As Lincoln is also involved in the food chain. Distributed in a large number of bivalve molluscs

Various land waters, and is considered an ecosystem biological indicators. Any

Changing the surrounding environment, has internal physiological bivalve molluscs.

Pandharpur is one of the famous pilgrimage center, attracting millions of believers

Various yatras. Human interventions affect the water quality of the river Bhima. In

This study attempts to understand the effects of changes has been the main

Breathing bivalve molluscs, Indonaia cyan. Experiment

15 days interval of 5 for 15 days respiration rate analysis

As a control experimental group. Oxygen consumption rate changes are:

Compared with controls, and that disturbed physiological adjustments. Result

As discussed in the pH change rate of the concentration of keywords physiological changes:

pH, respiration, cyan Indonaia,: Pima River.

Introduction:

Many biotic and abiotic factors affecting bivalve molluscs respiration rate (Bain, 1976).

Domestic and industrial wastewater can change a variety of physical and chemical parameters of aquatic bodies. On

Parameters are pH and attention because it is the industrial discharges into the ocean it'simportant

Environment has been studied by the (Perking.1976). Vedhapathak. Et al (2011) studied the rate of oxygen

Consumption, ammonia excretion advertisement O: N ratio of freshwater bivalves Indonaia cyan Godavari

River Paithan. effect of pH very little work has been reported in accordance with the rate of change

Breathing rivers from India, especially from the Pima heavily polluted river from the west

Maharashtra. Therefore, this investigation has undertaken to keep in view the importance and

Rich freshwater mollusks, cyan Indonaia from Pima River and the impact of changes in pH

Effects on respiration were studied.

Materials and Methods:

Freshwater bivalves, Indonaia blue river banks collect from Pima Gopalpur site (latitude 17O 66'N 75 ° 36 'east longitude), in November and December 2012.The animals

There, the size of 5864 mm, select test shortly after collection. The animals

Back to the lab and clean removal of algal biomass advertising mud. Ago

Experimental animals were acclimatized under laboratory conditions one week. And grouping

Divided into three batches, each containing 30 hatch. The first to be deemed to control the pH 7.4

And the second batch of bivalve molluscs containing 30 animals exposed to pH 6.0 (acidic). Third with 30

Animals are exposed to a pH of 8.0 (basic). I think considering the control batch and batch II and III

As an experiment. Bivalve molluscs carried out 15 days (chronic effect of pH

Effect). Interval 5thand 15 天 control group and experimental respiratory rate determined

Water is changed during group experimentationto duration of 12-130 hours. In order to obtain an acidic pH, 20% 1N

The use of hydrochloric acid, and the obtained alkaline pH, using 40% of 1N NaOH. PH value

Water holding the duration of the experiment animals confirmed the digital pH meter (ELECO

Hyderabad). Rates of individual animals from the control and experimental O2consumption

According to the modified Wrinklers determined, the specific use of freshwater (Golterman. etc.

1978). For the determination O2consumption, a total of five individual animals from each group were used (control group,

a pH of 6, pH value 8) and O2consumption individual animals in each group was measured and the average

And standard deviation values were determined from each of the groups that the oxygen consumption. To

Confirmation, and statistical analysis, triplicate readings is oxygen

Estimates. Criteria for the determination of oxygen consumption of one liter bottle breathing

Use siphon inlet and outlet. In order to determine the oxygen consumption of individual bivalve molluscs,

indonaia cyan, oxygen content were measured in the beginning of the experiment, after one hour

Animals exposed to a liter tank containing breathing apparatus tightness test.

Five separate bivalve from the average of each group statistical analysis to be used for

Know the great value, Results and Discussion:

The change rate of the oxygen consumption of the experimental results shown in

Following the table in Figure no.1and One

Used in the experiment of the physical and chemical parameters of the water temperature

18.22oc, pH value of 7.2-7.8, the oxygen content of 5.8-6.2 mg / l, total hardness of 105-110 ppm. Rate of oxygen

After spending the first five days, the control group was 0.0700Â ± 0.0046 O2/lit/gm/hr's. In the experiment

Groups reduced to 70.14%, a pH value of 6.0 (acidic), and at a pH of 8.0 (base) in the experimental group, which is

Decreased by 46.14%. On the other hand, the control group of the experiment after 15 days, the rate of oxygen

Consumption O20.0471Â ± 0.0019 mg / g / l / hr. After 15 days in the experimental group at pH 6.0

(Acidic) fell 30.57%, pH value 8.0 (basic) O2 content of 29.51%, reducing the time

With the respective control group. From our findings, in general, it can be said that after five days of

Experimental bivalve acidic and alkaline significantly reduced significantly

Oxygen consumption rate. Acidic groups decreased respiration rate, but also highlights

Basic group. However, the decreasing pattern still maintain 15 days after the change

At pH (acidity and alkalinity) noted that in bivalve molluscs. This clearly shows that changing any one of

Physical-chemical parameters (pH value) will certainly affect the physiological status of bivalve molluscs

River Pima Pandharpur's. change in pH animal metabolic rate can be changed, because the

Acidic and basic groups because the pressure imbalance. May change due to respiratory metabolism

Overall weakened animals. Universal Polites (1980) studied the oxygen absorption and

Transportation molluscs prosobranch, Busycon conalicultum gas exchange and response

Hypoxia. thurberg, et al, (1974) noted that any alternate metabolic rate may be a path

Showed biochemical composition may involve compensatory mechanism

Various stress conditions. Oxygen consumption is considered to be two metabolic rate as an indicator, as well as

Indicates the status of the stress conditions (Cantelemo, 1977) of the organism. In the present study, it can be

Said decrease in oxygen consumption may be due to stress conditions, as change in pH

This effect may be due to substantially the target organs, such as gills, may be responsible for reducing the

Oxygen consumption. Siddaki (2010) observed oxygen consumption declined from fish, Clarius

Toad, let them come into contact with the metal stress (copper sulfate), Shelke Wani (2005) observed

From: freshwater Amblypharyngodonm overturned after expressing their oxygen consumption

Stress and that various metals, gill damage can reduce the impact of the metal

The oxygen absorption efficiency of the organism. This may be the same as this investigation,

Bivalves Indonaia blue changed pH (acid and alkaline) may have been caused by the stress exceeds the gills, and then change has reduced the metabolic rate of oxygen consumption. However, further

Investigation and respiratory metabolism with special requirements in endonuclease analysis concerns
