Saltwater fish species New England

New England Aquarium biologists are cautiously optimistic about a rite of Spring that could be on the rebound. River herring are returning to the Back River in Weymouth and other coastal New England waters in encouraging numbers this year!

For centuries each spring, the diminutive river herring returned from the sea to spawn in the freshwater streams and ponds of coastal Massachusetts. Despite pollution and development, hundreds of thousands of the fish still returned to suburban South Shore communities well into the 21st century. Then throughout New England, the river herring numbers crashed. The natural spectacle of the spring migration up coastal streams suddenly became much more quiet. In 2006, the state of Massachusetts imposed a ban on harvesting the river herring from coastal waterways. on under the Endangered Species Act.

However, over the past two weeks in Weymouth, Mass., dedicated volunteers and local officials are abuzz about the number of herring that have returned to the built-up Back River. Nearly a quarter million of the fish have been counted with weeks to go in the spawning season. In 2005, there were only 80, 000 during the entire spring. This positive trend has been reported in many other coastal rivers throughout New England. Biologists are cautiously optimistic.


Copper is also toxic to fish, especially

Goldfish. There are several vital dyes that are relatively safe for FRESHWATER fish with ich (I know nothing about saltwater fishes) that are sold in pet stores: methylene blue is very safe for fishes but kills plants. There is a more commonly used drug now, malachite green, which is safe for plants and fairly safe for most fishes. But I believe a few kinds of FW fishes have trouble with it.
If I remember right, you don't have to change the water after using M.G., it naturally breaks down. But you will after M.B., first because it stains the water a deep blue, second because of your plants
