The median salary is not as likely than the mean salary to be skewed by outliers, for example, an extremely high salary or an extremely low salary that only a few people may earn. For example, when you put the earthworm farmers' salaries in numerical order, you discover that the median is $19,000.
Most spawning activity occurs at water temperatures around 10 C (50 F). Spawning can take place in streams or along shorelines. Rainbow smelt are found in streams and rivers only during their spawning migration. Females sized 185 to 224 mm (7.3 8.8 in) in length can release from 21,000 41,000 eggs each (Becker 1983).
20. A typical female brown trout produces about 2,000 eggs per kilogram (900 eggs per pound) of body weight at spawning. 21. Trout, like most other fish, cannot regulate their body temperature â they tick over at the same temperature as the water in which they swim. The temperature tolerance levels of trout range between a couple of degrees up to around 25Â°C. However, trout will be uncomfortable in water above about 20Â°C.
