Yes, young or small fish may be harmed by freshwater jellyfish if they encounter them. We have put small minnows into an aquarium with freshwater jellyfish and some have died after being stung. See similar questions...

Some larger fish may eat them, although we do not have direct evidence of this. We do know that they can be eaten by crayfish and turtles. See similar questions...

Yes. Like true jellyfish, they do have stinging cells (cnidocytes). This mechanism is designed for feeding, as the cnidocytes are utilized to paralyze macroinvertebrates and even small fish. There are conflicting reports whether these microscopic stinging barbs can penetrate human skin. Some individuals have reported that they encountered the jellyfish and felt it.

Maintaining freshwater jellyfish in an aquarium is not easy. They usually live only few days to a couple of weeks in an aquarium. The filtration system must be such that the jellyfish are not sucked into the filter. Even a sponge filter has the potential to trap the jellyfish. A pump system that circulates the water, rather than bubbling air, is needed. Air bubbles could become trapped under the bell of the jellyfish, forcing the animal to the top of the water and holding it there. See similar questions...

We use nets to catch the jellyfish. Sometimes we use a long-handled, large fine mesh dip net (12-16 inches in diameter), and sometimes we use a small size aquarium net. It just depends on where we are working and how quickly we want to gather a quantity of them. this point, we do not know. The freshwater jellyfish has been found in a variety of water types. We have observed them in waters ranging from crystal clear rock quarries to soupy green farm ponds. See similar questions...

Freshwater jellyfish could enter a pond in a variety of ways. For example, they could have entered in the polyp stage attached to plants. The plants could have been carried in by birds, on the props of boats, on the bottom of boat trailers or in the buckets of fishermen. They also could have entered in the medusa form in the bilge water of boats, in the water of bait buckets, or by flooding from another site. See similar questions...

There are two schools of thought as to the origin of the freshwater jellyfish. One is that they originated in the upper Yangtze River basin in China, where populations are still found today. They then were discovered in water lily tanks in Regents Park in London in the late 1800's, presumably having arrived there as polyps on the imported plants. There is nothing specific in the literature to as to how the organisms might have gotten from either China or London to the U.S. See similar questions...

The freshwater jellyfish feeds on microorganisms in the water column. So, they are competing with other organisms which feed on the same sources. This may impact fish populations in a body of water, especially if there is a large, established population of jellies. To date, there is no research evidence to support or refute this. Our affect on jellyfish is unknown. We have discovered them in pristine waters as well as heavily polluted waters. See similar questions...

The tentacles are covered with thousands of stinging cells. Smaller organisms which come in contact with the tentacles are stung and paralyzed. The paralyzed prey usually stays tangled in among the tentacles. The tentacles then sway about moving the captured prey to the mouth, which is in the middle of the underside. The bell (body or umbrella part) of the jelly goes through several contractions to move the prey into the mouth and digestive cavity. See similar questions...

Organisms, Craspedacusta sowerbii that are occasionally seen in our reservoirs that look like small marine jellyfish actually belong to a different taxonomic class, Hydrozoa, which includes the common hydra. These mostly translucent organisms are about the size of a quarter and feed on tiny zooplankton. Large, non-translucent gonads hang on their underside make them easier to spot on sunny days during the late summer. See similar questions...

If you are interested in breeding your fish, you should consider young fish. Our members generally prefer to buy five or six juvenile fish and grow them up together so that natural pair bonds will develop. If you buy five or six fish, the odds are strongly in your favor that you will have at least one male or female. Virtually all juvenile fish found for sale at GCCA's monthly meeting mini-auction are tank raised by our members. See similar questions...

It is a misconception that is often found in the literature and popular reports that C. sowerbii is rare. It is found on all continents, except Antarctica. As you can see from our maps, it is has been reported from most states. In Pennsylvania, they have been reported in 50 of our 67 counties. What is true is that their appearance is sporadic and unpredictable. We are currently in the process of doing DNA fingerprints (nuclear) on specimens from all over the U.S. See similar questions...

the Mediterranean Sea, Australia and South Africa are all infested with jellyfish some of the time. World wide, there are more than 100 million beach goers that are exposed to the jellyfish hazard. Look for the jellyfish world map to find a specific jellyfish location. See similar questions...

You should be asking, why are you guys so obsessed with fishing? Well we like to think the product we offer every day is a "big catch", the "big fish". But sometimes when you cast your line, you bring up something that's not quite a big fish, but still tastes good deep fried. In short the small fish is a smaller offering that didn't quite make it to the main spot. Sometimes if you're lucky you'll catch a repeat of a past catch, offered as "small fish".

Symptoms: Fish look like they have little white salt grains on them and may scratch against objects in the tank. White spot disease (Ichthyopthirius multifiliis) is caused by aprotozoan with a life cycle that includes a free-living stage. Ich grows on a fish --> it falls off and attaches to gravel or tank glass --> it reproduces to MANY parasites --> these swarmers then attach to other fish. See similar questions...

The realigned river channel will be designed so there is no physical or hydraulic obstruction to fish passage. A variety of substrates and micro habitats will be provided along the channel to minimise impacts on fish. A comprehensive monitoring program for the Freshwater Sawfish is proposed. See similar questions...

Care must always be taken when applying the product. Cover all fish pools or tanks, remove birds and animals from the area only while applying the spray. See similar questions...

There are a few reasons to this. Please check on the pH level of the water. Check the sex of the fish. Another reason can be the strain of this particular breed does not have a big protruding forehead. See similar questions...

No, not when applied correctly. At Goliath Termite and Pest Control we do not apply pesticides to water.

Moon jellies are certainly the most common, but several others occasionally make landing. Portuguese man-of-war can often be blown in with a strong storm from the South. Sea Nettle, Mushroom Jellies, and cabbage Head Jellies are also known to be off the coast and can be blown into shore. Lions Mane Jelly Fish are among the rarest to wash up. They can be as large as 8 feet across and have tentacles 100 feet long. See similar questions...
