Morfometría externa de alevines de Arapaima gigas (Cuvier, 1829) (Pisces, Osteichthyes, Osteoglossidae)

Abstract

A strategy for diversification of farmed fish takes in account fast growing and big size fish, with a profitable processing. Paiche or arapaima, Arapaima gigas (Cuvier, 1829) is one of the biggest freshwater fish, up to 200 kg and 10 kg/year of growth rate. Its processing yields 57% of meat. Natural occurrence is in rivers and flooded areas of the Amazon basin, with temperatures of 24-32 °C. Natural and semi-extensive conditions are request for breeding. Fingerlings are recruited from basins and delivered in plastic bags filled with water and oxygen. It is important to check fingerlings degree of well-being after a starving long trip (coefficient condition) as well as an external biometric survey that lead to develop quality standards for arapaima fingerlings. Average coefficient condition was 0.64 in 3.92-31.3 gr fish, very uniform throughout the range studied. Measurements from different parts of its body were taken and referenced to the total length
