“…It is possible that D. fluviorum juveniles utilize similar habitats. Small D. fluviorum of close to birth size have previously been reported from the Nerang and Macleay rivers in southeastern Queensland and northern New South Wales, respectively (Moreton 1989, Macbeth et al 2002.…”

Thirteen elasmobranch species were collected during a 4-yr survey of the intertidal margins of Moreton Bay, a large subtropical embayment in southeastern Queensland, Australia. Stingrays were the most common large predators in the intertidal zone, with total catch dominated numerically by blue-spotted maskray, Neotrygon kuhlii (53.8%); estuary stingray, Dasyatis fluviorum (22.2%); and brown whipray, Himantura toshi (10.2%). There was a significant female bias within intertidal populations of N. kuhlii and D. fluviorum. Courtship behaviors were observed in July and September in D. fluviorum and in January for whitespotted eagle ray, Aetobatus narinari. Dasyatis fluviorum, a threatened Australian endemic stingray, remains locally abundant within the bay. Overall, the inshore elasmobranch fauna of Moreton Bay is relatively species rich compared with similar studies elsewhere in Australia, emphasizing the regional importance of this ecosystem.

“…In the present study, totally 866 fishes belonging to only five species were observed in the study area which may be due to the stable environmental condition at the study area. Similarly, high diversities were observed by (Morton 1989) in the Cochin waters and (Chandran 1982) in the Vellar estuary, and they attributed this is due to the stable environmental condition. The diversity values observed in the present study were comparable to the results of (Shanmugam 1985) in Vellar estuary and (Chandrasekaran 1986).…”

“…The fluctuation of physico-chemical characters in estuarine environment has a profound influence on the occurrence of the juveniles of fish stocks. The fish communities of the Australian estuary have been investigated by (Loneragon et al 1986;Blaber et al 1989;Morton 1989;Moyle et al 1986). The Arasalar estuary is located on eastern, side 100 km away from Rajah Serfoji Government College, Thanjavur, Tamil Nadu, India.…”

The physico-chemical changes may have the tendency to accumulate in the various organs of estuarine organisms, especially fish which may in turn enter into the human metabolism through consumption causing serious hazards. Hence, the present study was carried out to determine the physico-chemical characteristics of water and Ichthyofauna in Arasalar estuary in southeast coast of India for the period of 1 year during September 2012-August 2013. The environmental parameters such as, temperature, pH, salinity, DO, silicate, nitrate and phosphate were observed from Department of Zoology, Rajah Serfoji Goverment College, Thanjavur, Tamil Nadu, India. During the period of study, air temperature varied from 28.8 to 35°C. The surface water temperature also varied from 25 to 31.5°C. The monthly mean values of hydrogen ion concentration of water varied from 7.1 to 8.2. The salinity of water varied from 5.5 % to 34. Dissolved oxygen in Arasalar estuary was varied from 3.5 to 7.2 mg/l. The total phosphorus varied from 0.29 to 2.15 lg/1. The nitrate varied from 0.47 to 3.75 lg/l. The silicate content varied from 28.25 to 98.74 lg/l. Totally 866 fishes were collected belonging to 4 orders and 5 families. Mystus gulio was found to be the dominant species (25.40 %) in the study area.

“…The theraponid, P. quadrilineatus, dominated the assemblage but is found in other habitats such as harbours and rocky reefs (Morton, 1989). Juveniles of G. maculata is the only one of three sillaginid species recorded from the habitat which bears dark body bars as an adult It is also present in greater abundance than either S. ciliata or S.…”

“…This would suggest that the models of pharyngeal activity developed in the curre nt study (food treabnent, nutrient extraction and sound production) can not be extrapolated to members of the Zenarchopteridae. If this value is then extrapolated to the seagrass beds of the whole of Moreton Bay, an area of some 244 98 hectares (Morton, 1989), then the amount of seagrass material returned to Moreton Bay sea grass beds per day is 11.254 tonnes, and per annum is 4107.85 tonnes.…”
