1. 0Background of the Study In New South Wales, the Department of Primary Industries (DPI) is responsible for execution of the Fisheries Management Act 1994. As such, DPI functions to maintain and protect aquatic habitats through sound and effective habitat management. The agency recognizes that sustaining an abundant marine life is challenge especially when there are natural and man-made threats to aquatic habitats and fauna communities. DPI identifies three of the leading threats to fish habitats such as urban development and the growing demography; agriculture, urban and industrial developments in estuarine areas and land use.

These threats impact mangroves, seagrass, saltmarsh and coastal lagoon communities which serve as refuge to marine species. Land clearing, dredging, agriculture, reclamation and estuarial developments as well as removal of riparian vegetation, increased sediments, nutrients and pollutants in riverbanks and beds and the removal of organic matter from rivers causes the decline in the population of fish species. Other marine dilemmas include acid sulfate soils, barriers to fish passage, climate change, cold water pollution, fish kills, pests and diseases, removal of large woody debris and structures that modify natural water flow. . 0Statement of the Problem The achievement of the subsistence of fishery is main issue here. What the local government of New South Wales as well as the local people of MacDonald Valley and Wollombi Brook Areas is doing in protecting and sustaining fish biomass, seabed habitats, sustainable harvesting and exploitation of marine stocks and expanding fish population is critical. Sustainable fisheries management and habitat management would be the key in combating the threats to fish habitats as endowed by human activities and natural disasters.

What are fishing disturbances in the areas that contribute in interrupted production and eventual decline in populace would be another issue to deal with. Unproductive fishing practices ruin marine habitats and marine species and therefore sacrificing healthy marine ecology that provide for food and familial livelihood. Maintaining aquatic biodiversity, then, is important for the local communities residing in this area. 3. 0Objectives of the Study The main purpose of this study is to analyse the several activities or events that jeopardises effective conservation of that quality of marine life.

This research, specifically, purports to determine how these activities affect the water ecology and to distinguish the role of the people within the vicinity and the authority having jurisdiction in protecting and recovering key habitats. This research takes into account the practices that affect marine ecosystems, recognizing the economic, social and environmental obligation of the people. The study also seeks to evaluate how the lessening of fish population depletion and ensuring continuing sustainability and productivity among fishery is possible and MacDonald and Wollombi Brook areas. 4. Research Methodology This study will use the descriptive type of research. A descriptive research intends to present facts concerning the nature and status of a situation, as it exists at the time of the study and to describe present conditions, events or systems based on the impressions or reactions of the respondents of the research (Creswell, 1994). It is also concerned with relationships and practices that exist, beliefs and processes that are ongoing, effects that are being felt, or trends that are developing (Best, 1970). In this study, primary and secondary research will be both incorporated.

The reason for this is to be able to provide adequate discussion for the readers that will help them understand more about the issue and the different variables that involve with it. The primary data for the study will be represented by the survey results that will be acquired from the respondents. On the other hand, the literature reviews to be presented in the second chapter of the study will represent the secondary data of the study. The research will be presented in written form with the addition of data charts which will present the project’s results.

Pie charts and network charts will be needed to illustrate some of the analyzed data. This cannot be confirmed, however, until the research data have been analyzed. 5. 0Reference Best, J. W. (1970).
