This Bagridae-related article is a stub. Haematological and biochemical parameters and tissue accumulations of cadmium in Oreochromis niloticus exposed to various concentrations of cadmium chloride. These cells are found in the digestive tract. Thus, the parental care is performed by the male. Hormones thus play a role in regulating circulation, gas metabolism, buoyancy, corticotropin release, and smooth muscle contraction. and transmitted securely. Function: Prolactin affects milk production in mammals, but in fish it plays a role in controlling circulation. AF-cells are called alpha (A) cells. The current study aims to assess the cadmium sub-lethal concentration influence on growth and haematological and biochemical parameters of Mystus seenghala.
