Offshore geology of Pakistan and non-living resource prospects

Offshore geology of Pakistan is characterized by active and passive continental margins. These continental margins show very unique features such as an active Makran subduction zone in the west and the Indus delta and a submarine fan in the east. The geology of these features of Pakistan EEZ is inadequately known. This is a major obstacle in exploring mineral resources. Detailed study of coastal and shelf geology is needed for better understanding of the geology of the area and comprehensive evolution of its non-living resource potential. An understanding of the geological events including tectonic movements, sedimentation processes and geochemical history that comprise the geological history is very important to help in identification and estimation of resources. In Pakistan EEZ applying the current technology and undertaking research work to understand the seafloor features and mineral deposits associated with it will be very fruitful.

Enhancing capacity of fishing communities for resource management

International Collective in Support of Fishworkers (ICSF) undertook capacity development in six locations in five countries (India, Indonesia, Myanmar, Bangladesh and Thailand). Six workshops were undertaken to help communities develop proposals for the conservation and sustainable uses of fisheries resources.

Fishery resource assessment and monitoring in the development and control of fisheries in the Lake Volta

Gill-netting and rotenoning have been used for assessing and monitoring fish stock abundance in Volta Lake. The lake and the main gear types used on it have been described. Before a gill-net sampling plan was set up, a preliminary survey was undertaken which largely determined the final form of the plan. An investigation as to whether or not the lake was being overfished concluded that it was being underfished. Commercial and experimental catch data analyses disclosed that the adults of the small species were being little utilized. Commercial sized species were also not being harvested according to their apparent proportion in the population. Production is presently fluctuating between approximately 37,000 and 40,000 tonnes. A high correlation between commercial and experimental catch was realized. Developments which have followed in the wake of stock assessment and monitoring studies include: introduction of monofilament nylon net, development of a special scoop net to permit mass harvest of clupeids after they have been attracted to light, and the design of a larger canoe which would help to extend the fishery into open water. New regulation and management policies will have to be formulated in the light of new findings before a rational exploitation of all the species can be achieved.

Resource studies in relation to the development of African inland fisheries

The paper discusses relevance of studies on the resources to the decisions that have taken for the development of management of African inland fisheries. Particular emphasis is given to outlining the types of advice that can be provided by the biologist, without which the decisions taken can easily be wrong. The primary information concerns the magnitude of the potential yield from the resource, and how it compares with present catches. From this the possibilities for development can be assessed, or the need for management be determined. Methods of determining the potential, and the data used in their application are briefly reviewed. Because scientific advice on the resource is desirable as early as possible in the development of a fishery, simple but rather rough methods may be equally, if not more, valuable than more precise but more difficult methods.

Experimental fisheries resource survey of Lake Wamala: Annual report 1975

During 1975, two experimental fisheries resource surveys were conducted on lake wamala from 14th to 20th May and 10th to 16th July. The purpose of the experimental fishing on this lake was to provide information required to genrate enough scientific guidelines and advice for rational exploitation, management, development and utilization of the fishery resources in the lake.
