- how often do fresh water clam reproduce -Freshwater clams, or mollusks, have a very unique way of reproducing. Freshwater clams can be miles away from their mate at the time of fertilization. All clams set their eggs and sperm free in the water, but freshwater clams depend on the current to successfully create new life. read further at http://animals.mom.me/reproduction-freshwater-clams-9682.html
- how to care for a fresh water clam-As these supplements dissolve, a Freshwater Clamwill begin filter feeding them out. Keep in mind it’s important to avoid overfeeding as access organic matter in aquarium water will lead to water quality issues. Use common sense and test tank water for ammonia levels often. learn more at https://www.aquariumcarebasics.com/freshwater-clams/
- how often does fresh water clam reproduce-Freshwater mussels have an unusual and complex mode of reproduction, which includes a brief, obligatory stage as a parasite on a fish. … While attempting to eat the lure, the marsupial gills of the female mussel are ruptured, and the fertilized eggs come loose and attach themselves to the fish – the host fish is infected- learn more https://molluskconservation.org/MUSSELS/Reproduction.html
- how does a fresh water clam breath-In the summer when mussels are ready to reproduce, the males merely release sperm into the water, and the females catch what they can. The sperm is siphoned by the female and used to fertilize her eggs internally. Obviously, if they aren’t grouped fairly closely, reproduction is hard to achieve. learn more at https://www.kingcounty.gov/services/environment/animals-and-plants/freshwater-mussels/life-history.aspx

- Freshwater Clams for Natural Filtration-Native to temperate freshwater rivers and lakes around the world, the freshwater clam is a bivalve mollusk that acts like a living filter to help keep aquarium water clean and clear. Freshwater clams such as the Corbicual sp., which originate in Asia and have a brown shell banded in black, help filter your aquarium water by removing detritus and uneaten food from the water column; in doing so, they remove the organic material that would otherwise break down in your system. The end result is reduced nitrite levels and improved water quality. learn more at https://www.drsfostersmith.com/pic/article.cfm?aid=2947
- is a fresh water clam bite a problem-The aquarium store called it a “shark tooth clam.” I was wondering if I could place it in my freshwater 20-gallon tank. learn more at https://www.petcha.com/freshwater-clam-problems/
- minnesota fresh water clam mussel with pearl-The pearls came from freshwater mussels or clams found in the Mississippi and other rivers and streams. They were most likely found while using the mussels for food and the shells for tempering pottery. Today, pearls are available in several types, natural or cultured and freshwater or marine. learn more http://www.greatriver.com/pearls.htm
- fresh water clam predators-Predators. Primary predators of freshwater mussels are muskrats, otters, raccoon, geese, ducks, flatworms (on juvenile mussels), fish, and humans.https://www.dnr.state.mn.us/minnaqua/speciesprofile/freshwater_mussels.html
- do fresh water clam eat cattails-What clams do remove quite efficiently are various forms of suspended algae. A grouping of a few small heavily feeding clams can clear the water in a 5-gallon aquarium within hours. They also filter out tiny creatures from the water. In a sense, they are filterers, just not the kind many pet stores market them -learn more at https://pethelpful.com/fish-aquariums/Introduction-Keeping-Clams-In-Aquariums
The pros and cons of adding fresh water clams in your filter media.
These are the response of my post at http://www.koiforum.uk/koi-carp-chat/20643-fresh-water-clam-living-filter-media.html
- I’ve heard if you keep them in your pond and they die they become toxic and kill your fish?
- They need cloudy green water as a food source, and hard water. They alse need a mud or sand substrate in the bottom to burrow into. They dont live long in a koi pond with clear water, and as Laura says die and rot in the water causing big problems.
As filters they are pretty useless as they excrete ammonia just like your fish.
Would not even consider them in a koi pond myself.
- Below is a link to my thoughts on using swan mussels as pond filters. It is easy to jump to the conclusion that, as swan mussels are filter feeders, they are useful in a koi pond because they filter water to obtain nutrients. But those who advocate that idea clearly haven’t thought the situation through and have ignored the parasitic larval stage where the mussel larvae (glochidia) that are released into the water attach themselves to fish gills to grow and develop. The injury they cause doing this makes them very unsuitable in any pond, let alone a koi pond.
There are differences between clams and mussels and I don’t have time to look into the laval stages of clams but my gut feeling is that, in such closely related species, the life cycle will be the same.
Freshwater clams are edible so when you remove them from your pond they will, at least, have some use.
- It’s my understanding that clams don’t have a parasitic larval stage, so don’t directly damage fish in the same way mussels can.
But their other disadvantages and lack of efficacy at biological filtration would make it a pointless exercise anyway in my book
- I don’t want to become sidetracked by the distribution of the swan mussel but, if you check, you will find that the Unionidae family of freshwater mussels have worldwide distribution.
However, on the subject of clams, I fail to see the purpose of adding clams to a pond. Their natural behaviour is to bury themselves in mud or silt so, unless you intend to allow the pond to become dirty, with all the associated parasite problems that would bring; the environment would be unsuitable leading to their early death.
I also did a quick Google for the life cycle of freshwater clams and, as I suspected, I found references to a parasitic larval stage. Click this for a description:
