dc.description.abstractThe aim of the current studywas to determine common physico-chemical parameters (salinity, temperature,chlorophyll-a, dissolved oxygen, andpH) of coastal water of two rocky shores from Buleiji and Paradise Point rockyshores at Karachi monthly basis, from November 2007 to April 2009. The range ofair and surface water temperature of Buleji varies from 19 ºC to 30 ºC and 21ºCto 29 ºC, respectively. Almost similar air temperature and seawater temperature(19º to 29º C) were recorded at Paradise Point. Salinity ranged from 35 to 39 ‰at Buleji while it ranged between 35 to 40 ‰ at Paradise Point. The lowestconcentrations of dissolved oxygen was recorded in November’07 and November’08at both sites, at Buleiji which were 1.6 mg/L and 1.7 mg/L while at ParadisePoint it was 1.8 mg/L and 1.7 mg/L, respectively. The pH value ranged from 7.0to 8.3 at Buleji and from 7.5 to 8.4 at Paradise Point. The concentrations ofchlorophyll-a were between 1.2 and 3.7µg cm-2 at Buleji while it ranged from 0.9 to 3.3 µg cm-2 at Paradise Point.Results showed that the obtained values of temperatures, salinity, pH and   chlorophyll-a are favorable for the continuedsurvival of marine biota but the values of dissolved oxygen were found to bebelow 4 mg/L which are not suitable for various species. Prolonged periods ofminimal dissolved oxygen directly upset larval stages of numerous marineorganisms. In Karachi coastal areas, seasonal accessibility of surface water isvery responsive to the monsoon climate and physiography of coastal belt. Theseconcerns were used to inform the common people and decision-makers about thestate of the coastal environments. To protect these dynamic significanthabitats, the government organizations and researchers should work withappropriate consideration.
