Statistics and Probability questions and answers. Population of 10,000 shellfish are approximately normally distributed with mean length of 10 cm and standard deviation 0.2cm. What length corresponds to the top 10% of shellfish lengths? The gastropod population declined to extinction in 1986, associated with the increase in shrimp density to 440 ind/m 2 and distribution to the lowest shore. Shrimp sediment destabilization was most likely to inhibit gastropod recruitment. The gastropod population began to recover in 1997 owing to shrimp population shrink.

The Salish Sea is home to an abundance of clams, mussels, oysters, crab and shrimp. Each acre of commercial Pacific oyster beds produces an overall value between $10,000 and $20,000 per year. Overall, shellfish harvest contributes roughly $180 million to Washington's economy per year, and 3,200 direct and indirect jobs.In 2006, estimated annual losses on the United States Pacific coast were between $0.95 and $1.87 million (2021 CAD) and between $0.07 and $0.14 million (2021 CAD) in 2011.

The shellfish population in a bay is estimated to have a count of about 1,000,000. Studies show that pollution reduces this population by about 2% per year, while other hazards are judged to reduce the population by about 10,000 per year. a. Write a...A length—age key was also generated in terms of probability to take into account the variability in growth rates, and with the multimodel approach it was not necessary to assume asymptotic growth. Population size structure is the most readily obtained and probably the most commonly used or only available information in a large number of ...Question: 1. Suppose we study the distribution of shell lengths for a certain species of shellfish. Typically, such lengths are distributed normally, so we can safely assume that the distribution of individual lengths is normal.Interannual variability in shellfish recruitment, population length composition, and total biomass is clearly evident in all bivalve species assessed as part of annual intertidal shellfish surveys conducted at eight Auckland beaches between 1994 and 2001.Mathilde Menoud, Simon Van Wynsberge, Gilles Le Moullac, Peva Levy, Serge Andréfouët, Georges Remoissenet, and Nabila Gaertner-Mazouni "Identifying Robust Proxies of Gonad Maturation for the Protandrous Hermaphrodite Tridacna maxima (Röding, 1798, Bivalvia) from Individual to Population Scale," Journal of Shellfish Research 35(1), 51-61, (1 April 2016). ...

Overfishing by man is the primary danger they now must overcome.

This Educational Research Brief summarizes the international and U.S. literature related to potential underwater sound impacts from offshore wind development on marine life, including marine mammals, sea turtles, fish, and invertebrates, with relevance to future development on the U.S. Atlantic and Pacific coasts.For fish or shellfish, it is recommended that the total length (size) of the smallest individual in a composite sample be no less than 75 percent of the total length (size) of the largest individual in the composite sample (U.S. EPA, 1990b).To evaluate evidence for human impacts on ancient fisheries, we assembled a 10,000 year record of shellfish harvesting from San Miguel Island shell middens.
