The life in the ocean would change and so would the gravity in the ocean. Therefore salinity is very important.
Higher levels of salinity produce brine shrimp that are smaller, but reach sexual maturity faster than those in lower levels. Also lower levels of salinity tend to allow more predators into the ecosystem.
salt levels in an aqueous solution
In open ocean evaporation affects the salinity of the oceans, in closed oceans the lack of sunrays cause greater salinity levels.
The salinity of Lake Eyre is increasing, and has changed dramatically over time. It was sampled in July 1974, and the minimum salinity value at that time was determined as 7%, and again in April 1975, when the salinity level was determined to be 40%. However, the percentage of salinity also seems to be seasonal. AsLake Eyre is currently full (May 2009), salinity levels are lower than they were prior to the wet season - but this is not always the case. When the floodwaters come from monsoonal rains in north Queensland, salinity levels are initially lower, but the problem is that, with the water flow, more saline is discharged from the Murray-Darling basin groundwaters, thereby oncreasing the salt content of Lake Eyre and the other salt lakes of inland Australia.
It is saltwater, but the salinity levels are lower than the oceans.
A hypersaline sea has elevated levels of dissolved ions (salts) as compared to normal saline conditions. A hypersaline sea has about 40 parts per mil salinity and the average salinity for the oceans is about 35 parts per mil salinity.

MANY different things. The standard set of strips test for: Chlorine levels Alkalinity levels (pH) Acidity levels (pH) Stabiliser Salinity levels (if testing in salt water chlorinated pools)
Biomass and temperature, erosion and mineral content.
There is minimal pollution in the Murray River. Its biggest problem is increasing salinity levels.
it's because of the quality of water they live in, salinity, ph levels etc..
Salinity is at its worst in the far west of New South Wales, particularly along some reaches of the Darling River. There are also increasing problems with rising salinity levels around Dubbo and Wagga Wagga. See the related link for a map.
