What are the Differences and Similarities between Freshwater and Saltwater Fish? There are many differences between freshwater and saltwater fish‚ as the anatomy (how they absorb and dispose of unneeded water‚ sizes and reproduction)‚ where they are located‚ climate‚ feeding and species. In addition‚ there are many similarities they share as they are some species that eats the same prey‚ the same food chain (the biggest will eat the smallest) and some parts from their anatomy (fish scales‚ gills

The Neritic zone is also called coastal waters‚ the coastal ocean‚ and the sublittoral zone. It is the part of the ocean extending from the low tide mark to the edge of the continental shelf. It is considered a shallow depth‚ extending to about 200 meters. The Neritic zone has decently well oxygenated water‚ low water pressure‚ and fairly stable temperature and salinity levels. This is the location of most of the sea life in the ocean. Salinity is the level of salt in the water. The Neritic zone

The Impact of Overfishing Overfishing has become an enormous problem all over the world. The impact of the increasing demand for fish and the advanced techniques made in the area of commercial fishing has caused some species of fish to be virtually extinct. In fact‚ some species like the giant bluefin tuna widely used by Japanese chefs and served in many restaurants‚ are now just few years away from extinction. Human demand for fish has increased enormously over the last several years‚ particularly

Lab Activity #3: Collection and Identification of Plankton at Lake St.George Discussion Questions 1. Phytoplankton are the organisms that were the most abundant in my sample‚ specifically from the Protista kingdom 2. I think that phytoplankton are more indicative of oligotrophic lakes‚ where-as zooplankton are more indicative of eutrophic lakes. I think this because‚ since phytoplankton are capable of producing their own energy‚ they don’t need the nutrients that eutrophic lakes offer‚ and they would
