Molluscicides (/ m ə ˈ l ʌ s k ɪ ˌ s aɪ d s,-ˈ l ʌ s-/) [1] [2] – also known as snail baits, snail pellets, or slug pellets – are pesticides against molluscs, which are usually used in agriculture or gardening, in order to control gastropod pests specifically slugs and snails which damage crops or other valued plants by feeding on them.
These snails are sometimes viewed as pests in aquarium tanks with fish, because the snails create waste, reproduce very often, and are very hard to remove completely. However, some aquarium owners deliberately choose to add these freshwater pond snails to their tank because the snails will eat uneaten fish food, algae and waste, as well as ...
The red-rimmed melania (Melanoides tuberculata), [3] [4] also known as Malayan livebearing snails or Malayan/Malaysian trumpet snails (often abbreviated to MTS) by aquarists, is a species of freshwater snail with an operculum, a parthenogenetic, aquatic gastropod mollusk in the family Thiaridae.
The assassin snail typically grows to 0.7–1.25 in (18–32 mm) in size, though this is dependent on food sources; they are usually smaller when kept in an aquarium. [ citation needed ] The shell, which is conical in shape, often consists of dark brown and yellowish tan bands, leading to some people to refer to it as the bumble bee snail, a ...
Lymnaea stagnalis snails can be easily be kept in a freshwater aquarium at room temperature, and fed with various sorts of vegetables, salad, cabbage, fallen maple or oak leaves, cucumber slices and dandelion leaves. Fish food will also be eaten, as well as aquarium pests like algae, the Hydra viridissima polyp, and the eggs of other water snails.
The decollate snail (Rumina decollata) will capture and eat garden snails, and because of this it has sometimes been introduced as a biological pest control agent. [57] However, this is not without problems, as the decollate snail is just as likely to attack and devour other species of gastropods that may represent a valuable part of the native ...
The two major classes of molluscs have representatives in freshwater: the gastropods (snails) and the bivalves (freshwater mussels and clams.) It appears that the other classes within the Phylum Mollusca -the cephalopods , scaphopods , polyplacophorans , etc. - never made the transition from a fully marine environment to a freshwater environment.
In 1980, the apple snail was introduced to south-east Asia as a food item and aquarium pet. First, it was introduced to Taiwan, then Japan, then Thailand and the Philippines. Instead of catching on, snails were released or escaped and have become a major agricultural pest. [16]
