An integrated study of the Mpenjati estuary-beach system. (Biological component) Abstract A study was carried out to find the abundances of animal organisms between both sides of the Mpenjati estuary. Zooplankton‚ Macro fauna‚ Meiofauna and Fish was sampled .Each of the species that reside in the estuary contribute to the diversity of the area and are essentially driving forces‚ ensuring optimal functioning of the ecosystem. The purpose of sampling such ecosystems is to find out how the interactions

(eg: phytoplankton or pondweeds or both) and some fishes fed on other animals‚ where the word of ‘’predator’’ usually implies on them (Shelby D. Gerking‚ 1994). However‚ Shelby D. Gerking (1994) also state that some fishes prefer phytoplankton and zooplankton (eg: plankton predator) and benthic predator more prefer pondweed and invertebrates living on the bottom as their nourishment. These show that food habits of the fishes fall into three categories‚ which is herbivorous‚ carnivorous and omnivorous

in size could have a larger impact on the food chain (“Living on Earth”). Zooplankton‚ a much smaller organism than the gray tree frog; the zooplankton wasn’t not able to survive in the water with high levels of salt. If the zooplankton die out then the body of water’s algae contented would increase but not only that‚ the fish that feed on zooplankton would die out‚ creating an imbalance in the food chain. The zooplankton get stressed in the high salt environment‚ just like humans get dehydrated

down into two categories: o Freshwater‚ which includes rivers‚ streams‚ ponds‚ lakes and freshwater wetland. o Marine or saltwater‚ which includes oceans‚ seas‚ estuaries‚ coral reefs and saltwater wetland. Each of these aquatic ecosystems can be defined by variables such as temperature‚ the presence or absence of light‚ and the availability of nutrients. Aquatic biomes cover almost all the world (around 75% of the surface) and only 3% of them are freshwaters. Freshwater ecosystems This ecosystem

However due to over exploitation‚ pollution and habitat destruction‚ we are losing the freshwater species faster than the marine and forest ones. Therefore‚ we need to protect them

Brook Trout Fishing The general term that is particular to a number of class that belong to the salmon kin Salmononidae is Trout. Trout is a freshwater fish that frequently seen in the streams and brooks over North America. All fish that are suitably named as trout‚ has been classified as a member of subfamily Salmoninae. Salmoninae has been divided into three genera subfamily mainly; Salvelinus which consists of fish pertaining to char or charr together with brook trout‚ the Oncorhynchus which

a) Describe the physico-chemical qualities of water that are important to aquaculturists. Aquaculture can be defined as the high-density production of fish‚ shellfish and plant forms in a controlled environment. Stocking rates for high-density aquaculture are typically thousand fold greater than wild environments. Modern fish culturists employ both open and close systems to raise fish. Open systems‚ such as‚ the raceways are characterized by rapid turnover of water. Closed systems are commonplace

Keywords: Darbandikhan‚ lake‚ physico-chemical properties‚ rotifera density INTRODUCTION The rotifers are among the most common inhabitants of freshwater everywhere. Some also live in brackish water and few in the ocean or on land in damp sites (Jordan and Verma‚ 2009). Rotifers are obligate aquatic animals that are reputed to have particularly efficient mechanisms to survive extreme or prolonged

Primarily swift predators of open seas; some of the smaller species strain zooplankton through their gill rakers. Example of a Scombridae. This one’s a mackerel. Mode of locomotion is Thunniform: Most fishes move by generating an undulating wave along their bodies along their bodies that pushes water backwards but thunniform

Mangrove Case Study A mangrove ecosystem is a general word that covers trees that are able to live in the conditions of shallow water area. There are many different plat families and these plants are able to survive regular flooding as well as fresh and salt waters. The mangrove trees must withstand being submerged twice a day by saltwater tides. The soil in which these trees grow in maybe sand but it is mostly rich mud. This rich mud is high in nutrients but low in oxygen. Mangroves have these
