water cycle is the means of how the Earth’s constant supply of water is being recycled. It is imperative that this cycle exists, so that water is able to reach plants and animals; provide nutrients and sedimentary movements throughout different aquatic ecosystems; and is able to contribute to Earth’s climate variability. Evaporation controls the loss of fresh water, and precipitation regulates the gains of fresh water. The discovered relationship between the two processes is that inputs from rivers

Light is easily diffused through air, therefore an adequate amount of light for photosynthesis reaches all terrestrial ecosystems. On the other hand water affects the penetration and spectral characteristic of light. Light in the red end of the wavelength spectrum is filtered out sooner than light from the violet end of the spectrum. Sunlight can only penetrate to a depth

Conceptual Framework of Ecotourism Ecotourism is defined as a “purposeful travel to natural areas to understand the culture and natural history of the environment, taking care not to alter the integrity of the ecosystem, while producing economic opportunities that make the conservation of natural resources beneficial to local people” (McCormick, 1994). Based on this definition, the conceptual framework was formulated. The operationalization of the framework included an assessment procedure

Chapter I INTRODUCTION Background of the Study One of the major sources of protein in human diet is fish. In fact, marine animals were assumed by ancient writers to be symbols of good health. However, nowadays, marine animals are far from being representatives of good health. They are subjected to diseases just as much as their terrestrial counterparts. Disease, in fishes, is closely linked to environmental stress. In the wild, they generally have some degree of freedom to modify their
