Evaluación de crecimiento y peso del cangrejo azul (Cardisoma crassum) con dos tipos de alimentos maíz (Zea mayz) y plátano (Musa paradisiaca).

Abstract

This research aimed to evaluate the growth and weight of blue crab, with two types of food: Corn (Zea mayz) and ripe banana (Musa paradisiaca). 60 specimens of crabs obtained from the public seafood supply center of the Pedernales Canton were used and the food samples were acquired in different places, which were corn (Veterinaria Serviagro) and ripe banana (Mercado de Pedernales). The samples were transferred to the facilities of AGROLAB Laboratory of Agricultural Chemical Analysis, in Santo Domingo de los Tsáchilas, individually packaged in plastic bags. Their length (cm), length and width were recorded with a caliper, total weight (g) with a gramera and sex. For the research, a cement platform 3.5 meters long and 1.25 meters wide was built, which were divided into 6 pens 40 centimeters wide to place 10 individuals per pen and 60 centimeters high, completing 60 individuals in total. of crabs (samples), corn (Zea mays) was applied to three pens and ripe banana (Musa paradisiaca) was applied to the other three pens. Fattening was evaluated using the Student's T method, which obtained the average, where corn (Zea mayz) was the best treatment, since the crabs gained more weight and no differences were found in growth because with neither of the two treatments. they grew up.
