The Blacktip Reef Shark is native to the tropical coral reefs of the Indian and Pacific Oceans. The Blacktip is listed under kingdom animalia, phylum chordata, class Chondrichthyes, order Carcharhiniformes, family Carcharhinidae, and genus Carcharhinus. This shark was given its name based off of the blacktip at the end of its dorsal fin. This fin appears very vivid in the shark’s youth, but fades with age. The Blacktip Reef Shark will most likely grow to be 4.9 feet and weigh roughly 40 pounds,…

impact: • HAB can affect tourism, public health, jobs, public safety, and coastal communities because it can contaminate water sources used for personal use, recreational use, and fisheries. The cost of red tide nationally have been estimated to reach $50 million with public health representing $20 million, commercial fisheries averages $18 million, followed by $7 million for recreation and tourism effects, and $2 million for monitoring and management 3. It can be difficult to determine the…

Wild steelhead (O. mykiss) populations are in decline across much of their native range. Nevertheless, steelhead remain an important sport fishery and a key management species for state and federal agencies. Steelhead managers are faced with a number of challenges associated with regulations and recovery goals imposed by the Endangered Species Act (ESA), while simultaneously attempting to maintain recreational angling opportunities. Factors affecting recruitment and survival of wild steelhead…

Evidence The giant catfish is uncommon yet broadly presented through the Mekong Basin. Mature fish seem to be found in major channels of the Mekong River and its tributaries. Juvenile fish seem to stick around wetland areas of the Mekong Basin. In the dry season mature fish migrate vast distances up river and start spawning when the rains arrive. The eggs and hatchlings are being transported downstream where juveniles may scatter into floodplains and other wetland zones. Not much information is…

Choose either Carbon Dioxide Removal or Solar Radiation Management: 1. Which did you choose? Carbon Dioxide Removal 2. Describe how it works. (1 pt) CDR is involves the reduction of the amount of CO2 in the atmosphere. First step is capturing carbon dioxide from the atmosphere, then compressing it and draining it into storage reservoirs. 3. What are two benefits of this technique? (2 pts) One benefit is that it brings down the CO2 level in the atmosphere. Another benefit is with less CO2 in the…

Fishing pressure is the main anthropogenic process threatening shark populations on a global and local scale. According to the United Nations' Food and Agriculture Organization (FAO) landings in the last six decades have nearly tripled, resulting in a worldwide decline of shark populations. The International Union for the Conservation of Nature (IUCN) carried out extensive assessments worldwide on the conservation status of shark species, and recently considerable effort has been placed on local…

farms, has recently become popular because it is thought to relieve pressure on fisheries by decreasing the demands of wild fish. However, the opposite is true in most cases because these fish farms require tons of wild fish to feed the farm-raised fish. For example, one of the most common types of aquaculture raises salmon, a species at the top of the food chain. These salmon farms do relieve pressure on the salmon fisheries, however they require tons of lower level fish to feed the salmon. An…

good fishing opportunities in Minnesota are typically drawn to the more famous larger lakes and the species of choice is most often walleye. Walleye fishing is a Minnesota tradition that stretches across generations. Perhaps the most famous walleye fishery in the state is Lake Mille Lacs. Because of its close proximity to the Twin Cites metropolitan area it is a very accessible destination for many anglers and has boasted phenomenal walleye populations for years. A bit further to the north are a…

fellowship in marine biology through John Hopkins University’s Master’s Program. During her time at JHU, she began focusing on the conservation of marine life. This focus soon became her career upon graduation when she took a job with the Bureau of Fisheries and Wildlife (Mahoney 2007).…

ICCAT is the International Commission of the Conservation of the Atlantic Tuna, and straight from the ICCAT website they describe themselves as an “inter-governmental fishery organization responsible for the conservation of tunas and tuna-like species in the Atlantic Ocean and its adjacent seas.” (ICCAT website). So basically they are in charge providing quotas, tracking, and managing tuna. It is not like ICCAT hasn’t…
