Finfish species raised in mariculture include salmon, cod, scallops, certain species of prawn, European lobsters, abalone and sea cucumbers. [31] Fish species selected to be raised in saltwater pens do not have any additional artificial feed requirements, as they live off of the naturally occurring nutrients within the water column.
Aquaculture means the sea cucumbers are farmed in contained areas where they can be cultured in a controlled manner. In China, sea cucumbers are cultured, along with prawns and some fish species, in integrated multi-trophic systems. In these systems, the sea cucumbers feed on the waste and feces from the other species.
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]
The tentacles are particularly vulnerable to predation by fish, but if they taste nasty, that enables the sea cucumber to spend a greater proportion of its time feeding, rather than having to keep retracting its tentacles whenever a fish approaches. [6] There are also some cup-shaped structures on the inside of the tentacles near the stem.
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.
Leptosynapta dolabrifera, the snot sea cucumber, is a small sea cucumber under the class Holothuroidea (1), in the family Synaptidae. It is most closely related to another species in its genus of 34 species Leptosynapta known as Leptosynapta inhaerens .
This is thought to help the animals move to new feeding grounds and avoid predators. [6] 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.
The biosynthesis of cucurbitacin C has been described. Zhang et al. (2014) identified nine cucumber genes in the pathway for biosynthesis of cucurbitacin C and elucidated four catalytic steps. [7] These authors also discovered the transcription factors Bl (Bitter leaf) and Bt (Bitter fruit) that regulate this pathway in leaves and fruits ...
