The sea cucumber ranges in size from 11 to 25 centimeters (4.3 to 9.8 in). [7] Its most distinct feature is its coloring, which is dictated by size: small enypniastes are a bright pink, and larger individuals are a more reddish-brown color. It is also semi-transparent, and its intestine can be seen through its body, especially after feeding. [8]
The female flower has a single stigma and is borne on a short stalk at the base of the flower panicle, with the spiky globular inferior ovary being immediately beneath. [3] The fruit is a prickly, inflated capsule up to 5 cm (2 in) long with two pores and four seeds. [2] It resembles a tiny spiny water melon, or cucumber, but is inedible. [4]
The Philippine "Balatan" or Sea cucumber breeding/harvesting. Sea cucumbers to be used as broodstock are either collected from the wild or are taken from commercial harvests. [2] [3] Only the largest and healthiest individuals are used for broodstock, as the success of a hatchery relies on the healthy condition of brood individuals. [2]
Freeze-dried and frozen fish foods were primarily developed for tropical and marine fish and are useful in providing variety to the diet or specialist feeding needs of some species. [4] These include tubifex worms , mosquito larvae , bloodworms , water fleas ( Daphnia and Cyclops spp.) along with brine shrimp ( Artemia salina ).
Typically, carnivorous fish or shrimp occupy IMTA's higher trophic levels. They excrete soluble ammonia and phosphorus (orthophosphate). Seaweeds and similar species can extract these inorganic nutrients directly from their environment. [1] [3] [5] Fish and shrimp also release organic nutrients which feed shellfish and deposit feeders. [5] [26 ...
Thelenota ananas, also known as pineapple sea cucumber, oloturia ananas, tripang, prickly skin cucumber, pointed teat sea cucumber, armoured sea cucumber, giant sea cucumber, sand fish or prickly redfish, is a species of sea cucumber [1] [2] found in tropical Indo-Pacific waters from the Red Sea and East Africa to Hawaii and Polynesia.
Sea apple is the common name for the colorful and somewhat round sea cucumbers of the genus Pseudocolochirus, found in Indo-Pacific waters. [2] [3] Sea apples are filter feeders with tentacles, ovate bodies, and tube-like feet. As with many other holothurians, they can release their internal organs or a toxin into the water when stressed. [3] [4]
With the help of the feeder, feeding mixed food to the fish, including fish flakes and fish pellets, becomes more manageable. The mounting system is typically in the form of hooks or brackets. However, some electronic fish feeders also come with suction cups that attach to the wall of the aquarium. [4]
