What are harmful algal blooms and why do they occur?
In this lesson plan, students will run their own experiments to investigate how eutrophication can cause harmful algal blooms and investigate strategies for preventing them.

Reports
The literature, minutes of conference, data reports and other records, pertaining to the 1963 Chesapeake Bay fish kills has been reviewed in detail. Data concerning the few 1964 fish kills in Virginia waters are also appended. The various theories concerning the cause(s) of the kills have been carefully examined. All evidence indicates that the fishes killed, died as a result of interaction between unfavorable environmental factors and, in most species, bacterial disease (protozoan disease in 1964). Among the likely environmental stresses involved were: 1) severe hydroclimate, rapidly changing temperatures, high salinities due to drought, 2) low and high oxygens, 3) …
