Hello all,
so I was doing a little research last night on nori sheets, and sweaweed sold as food for tangs, and they all seem to be Porphyra : It grows in the intertidal zone, typically between the upper intertidal zone and the splash zone in cold waters of temperate oceans. [from wikipedia]
more info on it if interested :
Porphyra contains significant amounts of protein, vitamins and minerals. The vitamin C content of nori, or prepared Porphyra, is greater than in raw oranges. The vitamin A content is comparable to that spinach, along with fairly high amounts of vitamin B in general. The amount of free and proteinaceous amino acids in nori are roughly similar to that of vegetables. Porphyra also contains a high amount of arginine, a basic amino acid which is generally found in animal protein. In nori, the characteristic taste is a result of the coexistence of relatively large amounts of alanine, glutamic acid and glycine. It also contains an abundant amount of taurine which is know to be effective for liver activity, especially in preventing the occurence of gallstone disease and for controlling blood cholesterol levels. Nori also contain relatively high amounts of essential trace elements, such as zinc, which is essential for certain enzyme functions. Manganese, copper and selenium are present in Porphyra and essential for the metabolic processes of organisms.
Porphyra does have a few medicinal benefits. It contains a sulfated polysaccharide called porphyran, which is a complex galactan. The physiological activity of porphyran in the animal body isn't clear right now, but studies have indicated some excellent health benefits from it. It may inhibit the growth of certain tumors. Also, when nori powder was mixed with a basic diet at 2% concentration and fed to rats, it preventd a purposely induced carcinogenesis. These results may be have been caused by the sulfation of the polysaccharide, which can enhance the effectiveness of it.
Another substance called porphyosin has been isolated from Porphyra. It appears to exhibit anti-ulcer activity in shay ulcers. However, porphyosin was found to be ineffective against stress ulcers.
does anyone feed their tangs anything differently ? maybe algae from warm waters they are used to eating ? how can I get such algae ?
