The fisheries industry or sector is one of the major sources of employment in Malawi with around 230, 000 of Malawians employed either directly or indirectly in the industry. As a result of the drilling of oil the lake is at risk of oil pollution which may lead to the endangerment of the fish species thus rendering the fisheries industry in Malawi doomed. In addition to the impact the drilling of oil has on the fisheries sector another negative effect of drilling oil is hunger caused by the extinction of one of the main sources of food for
First we will be talking about the negative effect. According to USGS (The United States Geological Survey) ever since the Introduction of Zebra Mussels to the Great lakes,” Large populations of zebra mussels in the Great Lakes reduced the biomass of phytoplankton significantly following invasion. And the Diatom Abundance as decreased by 82-91 percent.” Zebra Mussels consume plankton as food which leaves Small fishes such as young sportfish without as much food. These small fishes depend on Plankton for growth and survival. The Zebra
Moreover, Myers and Worm (2005), confirmed a general decline in large predatory fish communities worldwide by at least 90% over the last 50 years - 100 years. Many of international organization are attempting to identify the species and
Ice safety here, over the years, has been greatly enhanced and you are sure to find a wide variety of species underneath just waiting to pounce on your bait. Alaska Alaska is known for its great lakes and rivers. The main advantage about Alaska is that majority of the fishing grounds are in the proximity of urban areas such as Kenai Peninsula and Fairmont. Some of the fish you could catch here include; trout, landlocked salmon, pike, burbot, grayling and the rare sheefish which is found towards the state’s interior Utah The most notable place that everybody wants to visit in Utah is the strawberry reservoir. Anglers here enjoy the predominant species known as rainbow trout.
Once a habitat is physically altered, even if and when the invader is removed, it becomes difficult or impossible to reverse the effects. For example, Nile perch is a fish that can grow to enormous sizes, some measuring up to 6 feet long and weighing over four hundred pounds. They are considered to be one of the planets worst invasive species. They’re native to freshwater lakes and rivers in Africa and after being introduced to Lake Victoria in the 1950’s the population exploded. With such great numbers these species are responsible for the extinction or near extinction of several hundred native species.
However, some countries are able to control their population growth, such as London, Greece, Japan, Singapore and Israel. Many problems are caused when you live in an overpopulated city or nation to its residents, such as environmental and social problems. Daily, 25,000 people die due to hunger and 18,000 of them are under the age of 5, because their country can’t provide them with enough food to feed the entire nation. One billion people lack access to water throughout the world, because of water shortages. Another issue with water is citizens are trashing their oceans damaging the water we drink and the fish we breed.
Not only is it a popular cruise destination for tourists, it also enables about 3 million tonnes of container traffic every year.  The longest river The Nile and the Amazon vie for the rank of the world’s longest river. The Nile, flows for more than 6,800 km, traversing a dozen countries in Africa, and forming the primary source of water in Egypt and Sudan. Highly seasonal, the river transports only about 3 million tonnes of goods every year, and is more popular as a route for passenger traffic.  Amazon, arguably the world’s longest river at 6,900 km and flushing one fifth of the world’s fresh water into the oceans, has a vast untapped potential as an inland waterway.
Including hundreds species of ornamental fish which have won hearts of hobbyists worldwide. According to a 2008 data from thr Maritime Affairs and Fisheries Ministry, Indonesian water is home for 650 species of marine ornamental fishes and 400 species of freshwater ornamental fishes. Of the total 650 species of marine ornamental fish, 480 species have been identified and 200 species have been traded. Indonesian marine ornamental fish secure 20 percent of the world's market. Wild-caught fishes accounts for 95 percent of Indonesia's ornamental fish export, while the cultured fish contribute only 5 percent of the total export.
The Nile Perch is seen throughout much of the Afrotropic ecozone, as well as being native to the Nile, Senegal, Congo, Volta, Niger, Lake Turkana, and Lake Chad. The Nile Perch was introduced manually into Lake Victoria in the late 1950s and early 1960s. Lake Victoria covers a total of 69,000 square kilometres, shared by Kenya, Tanzania and Uganda. The Lake contains one of the most varied and endangered ecosystems. The Nile perch was initially introduced into Lake Victoria for commercial fishing purposes, where it then reproduced rapidly and spread throughout several aquatic environments in Africa.
The price of diesel will increase the cost of fishery activities and reduce the number of trips to the sea. Theoretically, if the production has decreased, the price of the product will increase. The price of fish will be increased due to the declining of total fish landing. As recorded by Fishery Development Authority of Malaysia (LKIM), the weekly retail price of fish has increased by 8.05% in fifth week of October 2013 compared to first week of January 2013. Based on a research done by the LKIM in 2008, Terengganu coastline once was a suitable habitat for various species of fish.
