The California Department of Fish and Wildlife said the estimated number of adult fall Chinook expected to return to spawn in the Sacramento River this year is less than 170,000, one of the lowest ...
It has been called "the central problem of fish population dynamics" [14] and “the major problem in fisheries science". [15] Fish produce huge volumes of larvae, but the volumes are very variable and mortality is high. This makes good predictions difficult. [16] According to Daniel Pauly, [15] [17] the definitive study was made in 1999 by ...
Fisherman Siem Huat has seen fish stocks dwindle in recent years in Cambodia's majestic Tonle Sap Lake, and with them, his family's sole source of income. Experts say extreme weather brought by ...
