For 6 years an artificial fertilizer is used on an apple orchard. The orchard is next to a stream which runs out into a small saltwater bay. Researchers have been sampling fish populations in the bay?

Over six years of artificial fertilizer use in the adjacent Apple orchard, nutrient runoff likely increased nitrogen and phosphorus levels in the stream, potentially leading to eutrophication in the small saltwater bay. This condition can cause algal blooms, depleting oxygen levels and harming fish populations. Researchers sampling the bay may observe shifts in fish diversity and abundance, as well as potential declines in sensitive species due to the altered ecosystem dynamics. Monitoring and management strategies are essential to mitigate these impacts on aquatic life.
