Ecological Survey around the Churna Island |
Charna Island is a small island located in the Arabian Sea off the coast of Karachi, Sindh, Pakistan. It is situated northwest of a fishing settlement Mubarak Village. Mubarak Village (Mubarak Goth), is located some 60 km from Karachi on Hawks Bay-Mubarak Goth Road. It is famous for the marine life around it, which includes barracuda, Narrow-barred Spanish mackerel, cobia, Dorado, Tuna, angel fish, sea urchin, sea fan, oyster, ray fish and rare green turtle.
The Churna Island (24 53.48N 66 36.16E) has a small coral reef and is ecologically significant and supports a rich biodiversity. The island is triangular and the dimensions are 1.5 x 1.5 x 0.8 kilometers. The protected site of the island is also a site for recreational diving and angling. Earlier studies (Kazmi & Karmi 1988) reported small patches of living coral colonies around the Churna Island, but no detailed studies are recorded. The Churna Island is one of the five site proposed as the Marine and Coastal Protected Areas on the Pakistan coast during the Regional Resources Coordination and Mobilization Workshop (2006).
NIO recently conducted a geo-referenced dive survey (Manta Tow and Transect-Quadrate method) covering the entire area around the Churna Island under the 6600 MW Power Park at Gadani Balochistan EIA (Marine Ecology) project. The survey will form a detailed baseline of the coral, surrounding ecosystem.
Detailed analysis is underway to form scientific publications and future collaborative research initiatives.
Pishukan Fish Landing Jetty
On a request of Gwadar Development Authority (GDA), the National Institute of Oceanography (NIO) carried out detailed bathymetric survey of the Pishukan Fish Harbour. The harbour is facing problem of siltation therefore to make it useful for small and large fishing boats, the Gwadar Development Authority decided to dredge the silt deposited within the jetty area. As a pre-requisite of a dredging, two bathymetric surveys are required to be conducted to determine the volume of silt that need to be dredged before the dredging and after the dredging.
NIO carried out the initial survey in February 2013. This report contains the details of the bathymetric survey and the data acquired. This report also contains the volume of sand at a pre-dredged stage. A comparison of present bathymetric data with the survey conducted by NIO in February 2013 is also included in this report.
