Seaweed Gracilaria changii as a bioremediator agent for ammonia, nitrite and nitrate in controlled tanks of Whiteleg Shrimp Litopenaeus vannamei

Abstract: Intensive shrimp cultures are characterized by high stocking densities and use large quantities of artificial feed. The artificial feed was consumed only a small part by shrimp, while the rest decomposes in ponds and produces inorganic nitrogen compounds such as ammonia, nitrite, and nitrate, which are poisonous to shrimp and decrease water quality. One alternative that can be applied to improve water quality in the shrimp pond is the use of bioremediation agents. One of the bioremediation agents is seaweed Gr… Show more

“…The amount of organic matter generated from shrimp mortalities and other waste products in intensive cultures have been reported to be largely influenced by the level of crude protein content of the feed and feed conversion ratio (FCR). For instance, at 1.2 and 1.5 FCR of 40% crude protein diet, 48 kg and 70 kg of organic wastes were generated per ton of shrimp production (Badraeni et al, 2020). The high levels of inorganic nitrogen compounds produced from the decomposition of this organic waste are known to be toxic to shrimp and results to mass mortality.…”
