fifteen years ago, fishing in the delaware bay was drastically different. the diminishing fish population reflects a downturn in water clarity and quality. bait turns brown within minutes of being placed in the water, and fish fight clouds of mud sweeping down the bay. just a decade and a half ago, \u201cyou would load 200-quart coolers up with croaker, and now you are lucky to catch three,\u201d said keith beebe, a charter captain from delaware\u2019s coastal town of lewes. each year, the fishing in this area has gotten poorer and poorer.<\/p>\n
some of the ways humans degrade water quality in coastal areas is through nutrient pollution, land-use change, and industrial contamination. the delaware bay and its tributaries are not only affected by activities in the immediate area, but from those that might occur at the far reaches of the watershed. these upstream inputs of pollution eventually work their way downstream to the bay where they are accumulated and compounded.<\/p>\n
\u201cone of the largest sources of pollution is from fertilizers that lead to nutrient pollution and eutrophication within our waterways,\u201d said taylor deemer, a master of science student in marine biosciences at the university of delaware, lewes campus. <\/p>\n
deemer explains that farmers anticipate losing a portion of the fertilizer that they put down on their fields to runoff from rain events. as a result, to ensure that their crops receive the proper amount of nutrients, they often put down extra. these nutrients are not just useful for promoting the growth of terrestrial plants, but also promote the growth of aquatic ones as well, such as phytoplankton. eutrophication is when these excess nutrients reach the bay, leading to what is known as algal blooms, which are proliferations of various phytoplankton species.<\/p>\n
phytoplankton is generally a good thing in aquatic systems, as it provides much of the oxygen that aquatic organisms need to survive. these bloom events, however, lead to bacterial growth that draws down the oxygen levels and lead to fish kills for those organisms that can\u2019t escape the area.<\/p>\n
options to combat nutrient pollution would be to simply use less pesticides, herbicides, and fertilizers. an additional option is to find methods of application that incorporate the fertilizers into the soil, rather than just spreading them across the surface where they run off more easily.<\/p>\n
