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.
Red racer snails are amphibious and occasionally venture above the waterline. They can tolerate freshwater, brackish water, and saltwater habitats. They are usually found in bodies of water with dense vegetation in coastal areas, like mangrove forests and river deltas. They primarily eat algae and biofilm. They lay eggs in clutches of 50 to 100 ...
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.
Fipronil is a broad-spectrum insecticide that belongs to the phenylpyrazole insecticide class. [3] Fipronil disrupts the insect central nervous system by blocking the ligand-gated ion channel of the GABA A receptor (IRAC group 2B) and glutamate-gated chloride (GluCl) channels. This causes hyperexcitation of contaminated insects' nerves and muscles.
In a model ecosystem with a terrestrial-aquatic interface, sorghum seedlings were treated with mirex at 1.1 kg/ha. Caterpillars fed on these seedlings and their faeces contaminated the water which contained algae, snails, Daphnia, mosquito larvae, and fish. After 33 days, the ecological magnification value was 219 for fish and 1165 for snails.
Estimates suggest 70% to 90% of aquarium fish exported from the Philippines are caught with cyanide. [ 2 ] [ 3 ] [ 4 ] Due to the post-capture handling stress and the effects of the cyanide, fish are bound to have a shorter life-span than usual in aquariums.
Karachi Municipal Aquarium was constructed in 1953. Located inside the Karachi Zoo, the aquarium has a total of 28 tanks which contain a total of around 300 fishes of about 30 species. [ 1 ] [ 2 ] It is one of the three public aquaria in Karachi, the other two being Clifton Fish Aquarium and Landhi Korangi Aquarium .
The practice of rearing snails for food is known as heliciculture. For purposes of cultivation, the snails are kept in a dark place in a wired cage with dry straw or dry wood. Coppiced wine-grape vines are often used for this purpose. During the rainy period the snails come out of hibernation and release most of their mucus onto the dry wood/straw.
