Lakes and reservoir
Lakes and ponds are bodies of relatively still, or standing, water.
Although no definite size distinguishes a lake from a pond, lakes generally are larger and deeper than ponds.
Water enters lakes from streams and rivers, by rain or snow falling on or near the depression, and from groundwater.
The american eel
The American eel is the only species of freshwater eel found in North America. It undergoes several physical phases through its lifecycle, beginning as an egg in the Sargasso Sea and transforming through larvae, glass eel, elver, yellow eel, and finally silver eel stages as it migrates from the ocean to freshwater habitats to mature before returning to the ocean to spawn. The American eel is economically important to the Atlantic Coast commercial fishing industry, though catch totals have declined from peak levels in the 1970s.
Coral Reefs
Coral reefs are ecosystems located in warm, shallow ocean waters that are home to many species. They are made up of coral polyps that secrete calcium carbonate to form hard structures. Coral reefs come in several types - fringing reefs lie adjacent to shores, barrier reefs lie further offshore, and atolls form from sunken barrier reefs, enclosing lagoons. Coral reefs support a diversity of life through symbiotic relationships and provide important benefits to coastlines and economies. However, they are threatened by human activities such as pollution, overfishing, and coastal development.
Degradation of Philippine Marine Life (2013)
The degradation of Philippine marine life and coastal ecosystems like coral reefs and mangroves is outlined. The Philippines has extensive coastline and marine resources but coral reefs have over 70% damage from threats like blast fishing, while mangrove areas have declined sharply from 500,000 hectares to just 117,000 hectares due to activities like aquaculture and development. Specific areas of concern are discussed like the Tubbataha Reef, a UNESCO World Heritage Site that suffered damage when a US naval ship ran aground in the reef in 2013.
Estuaries
Estuaries are bodies of water where freshwater rivers meet saltwater oceans, forming brackish water. They support rich ecosystems but are threatened by pollution and climate change. The Chesapeake Bay estuary is suffering from agricultural and industrial runoff, which is lowering oxygen levels and harming fish and crab populations. Rising sea levels and warmer water temperatures due to global warming are eroding wetlands and stressing native species in estuaries like Delaware Bay. Protecting these vital ecosystems is important for wildlife and coastal communities.
Fishery
The document discusses commercial fisheries and their importance for food and livelihoods in developing countries. It notes that over 100 million people depend on fisheries and that sustainable use is important to maintain balances in ocean ecosystems. The majority of fishing occurs on continental shelves, where conditions like shallow waters and nutrient circulation support phytoplankton growth and dense fish populations. Different fishing technologies are used for inshore and offshore fishing.
Circulatory system
The circulatory system transfers absorbed nutrients, oxygen, waste products, hormones, and more throughout the body. It has two main parts - the blood vascular system including the heart, blood vessels and blood, and the lymphatic system including lymph vessels and lymph fluid. The evolution of the vertebrate heart is traced from single-chambered hearts in primitive chordates to modern four-chambered hearts with separate pulmonary and systemic circulation in birds and mammals.
WEEDS & PLANKTONS AND ITS CONTROL
This document discusses aquatic weeds and plankton. It describes different types of aquatic weeds including floating, emergent, submerged, and marginal weeds. The growth of excessive aquatic weeds can be harmful as they shade ponds, obstruct fish movement, and cause oxygen depletion. The document outlines mechanical, chemical, and biological methods for controlling weed growth, and provides examples of specific chemicals that can be used to treat different weed types. It also discusses plankton types, their roles in fisheries and aquatic food chains, and how they serve as an important food source for fish.
