Download file to see previous pages The color of basking shark is typically blackish to grey-brown, grey or blue-grey above and below the body and fins, often with irregular white blotches on the underside of the head and abdomen (Compagno, 2001 from COSEWIC, 2007). Basking sharks prefer cool and temperate coastal shelf waters and are distributed worldwide. In the North Atlantic (Compagno, 2001), basking sharks are sighted in waters off countries as far south and east as Senegal, through Europe, Norway, Sweden, Russia, Canada, along the eastern seaboard of the United States and into the Gulf of Mexico. In the North Pacific, they are observed as far south and west as Japan, through to China, Alaska, British Columbia, along the western seaboard of the United States and Mexico (Compagno, 2001, from COSEWIC, 2007). Habitat requirements The habitat requirements for basking shark (Sim et al, 1997) are associated with the oceanographic events on zooplankton concentration. Fronts off headlands, around islands and in bays with strong fluctuation of water masses from tidal flow were also frequented. In a study conducted by Compagno (2001), it recorded basking shark in the epipelagic zone by aerial surveys, in pelagic driftnet fisheries and is caught in bottom trawls off the St. Lawrence River, Scotian Shelf and Scotland. Te Newfoundland Observer Program (NOP) also noted that basking sharks have been caught in trawl nets fishing in depths up to 1370m. Fifteen percent of the records from waters deeper than 1000m were also observed. Skomal (2005) suggested that basking sharks migrate to different wintering habitats. They are seen to be influenced by patterns of prey distribution, varying by depths, location, and season (COSEWIC, 2007). Observed on the habitat trends of the basking sharks is the consistency of target areas and preference for high concentration of zooplankton. This has been linked to both large and small scale oceanographic conditions that change quickly (Sims and Quayle, 1998, from COSEWIC, 2007). Reproduction and Mortality The pairing of the basking shark (Sims et al, 2000) is perceived to occur in early summer. This is based on the observed courtship behavior which is nose to tail circling, and scarring. The gestation period of basking shark with a litter of six young is at 2.6 years (Pauly, 2002). The assumed length at birth is 1.5m. The time between successive litters may be two to three years (Compagno, 2001) and like other lamnoid sharks, the basking sharks develop embryonic ovophagy which supplies nutrients to the developing embryos (Compagno, 2001, from COSEWIC, 2007). The longevity of the basking shark is approximated at 50 years. The age of maturity is about 12 to 16 years in males and 16 to 20 years in females (UK CITES, 2002). Generally, females are presumed to mature at larger sizes than males with an estimated size at 4.6 to 6.1m in length at the stage of maturity. Yearly productivity ranges from 0.013 to 0.023 based on the methodology of Smith et al (1998). They used age at maturity, maximum age and average fecundity. Smith et al (1998) suggested that the potential for recovery or rebound rate may be lower for basking shark when compared to other species of Pacific sharks. Pauly (2002) determined the natural mortality to be 0.068 based on the age of maturity at 18 years for female which midrange is 16 – ...Download file to see next pagesRead More

Shark finning industry argumentative essay
...? Shark finning industry Sharks, as a species, exist in oceans for about 400 million years (Verclar et al. 1078). The last decades, the population ofsharks globally is continuously decreased; the expansion of the finning industry is considered as the key reason for this phenomenon. Finning industry is based on the following practice: ‘the fin of each shark is chopped off and the rest is discharged’ (Verclar et al. 1078). Then, the fin is likely to be used for soup, after being diverted to the market, in its natural form or using appropriate package. The consumption of fin of sharks is quite common in many countries worldwide. However,...

...extensive research and several debates concerning the susceptibility of extinction of the male species. Proponents of this premise assert that there is overwhelming evidence that support this connotation. These reasons include the gradual extinction of the Y chromosome, reduced sperm counts as well as rise in estrogen levels in older men. Other reasons include the loss of social and reproductive roles by men due to increased awareness of women and artificial forms or fertilization respectively. Moreover, other chemicals that mimic the effects of estrogen for instance 'Xeno-Oestrogens accelerate this susceptibility.' These chemicals are present in most of the common products that men use...

There are only seven northern white rhinos living in the world (Rhino Info n.d). With then rhino, facing distinction in the future is inevitable that governments form laws that protect this endangered specie from human hunters who kill them for their horns, as well as meat.

The irony is that though shark fin soup involves much cruelty on the part of professional fisherman, with the increase in the income of Chinese population, the demand for the Shark Finn soup has been constantly on the rise. This is indeed worrisome and serious when one takes into consideration the survival and sustainability of the shark species. This is because the shark fins required to make Shark Fin Soup are collected from a range of shark species. Not only Shark Finn Soup is responsible for a decline...

The major elements here are the shark, Watson and the spear-handling man. This technique is commonly used in historical paintings. The painting’s use of light is also quite romantic as it uses soft light, and it highlights the action in the middle of the picture. The colors are subdued, understandably so because the subject of the painting is quite tragic in nature. There is no blood bath in this painting. This might be some form of censorship on the painter. This picture is unique because it uses a personal experience as a historical event. Add to that...
