👉Mass fishkill is a clear indication of the deteriorating health of the lake ecosystem
🌊Fishkill often happens when the dissolved oxygen (DO) — the amount of oxygen in the water — reduces drastically, choking the fish to death.
🌊Depleting DO is caused by a higher biochemical oxygen demand (BOD, often because of a high concentration of nutrients and organic matter that decomposes in an anaerobic condition, releasing ammonia or algal blooms in the water body.
👉 Why fishkill occur at night and are sighted early in the morning ?
🌊Aquatic plants release oxygen as a byproduct of photosynthesis during the daytime, they also absorb oxygen at night, this creates a DO crisis in water bodies, mainly after the sun goes down. So, most fishkill occur at night and are sighted early in the morning.
🌊 Many lakes have become dumping grounds for raw sewage and other effluents which increases the concentration of nutrients and cause High BOD , leads to choking the fish to death.
