Enriquecimento de Panagrellus redivivus com Arthrospira (spirulina) platensis contraposto ao uso da Artemia salina na alimentação inicial para desempenho zootécnico da larva de Betta splenderns.

Trabalho de Conclusão de Curso (Graduação em Engenharia de Aquicultura) – Centro de Biociências, Universidade Federal do Rio Grande do Norte, Natal, 2023.https://repositorio.ufrn.br/handle/123456789/57288In ornamental aquaculture, new ways are always sought to optimize growth with lower production costs. The present work evaluates the weight gain rate of Betta splandens fed with the nematode Panagrellus redivivus enriched with spirulina microalgae, as an alternative feeding compared to the already used Artemia brine. The experiment, lasting 30 days, was conducted with food management once a day offered ad libitum. A completely randomized design was used with a 3x3 distribution, with a stocking density of 5 larvae/liter. Treatments were divided into brine shrimp (A) being the control, Panagrellus redivivus enriched with spirulina (MS) and Panagrellus redivivus (M). At the end of the Experiment, it was identified that the weight gain in the Artemia (A) treatment had the highest average gain of 0.0022g, followed by feeding P.redivivus enriched with spirulina (MS) with an average of 0.0015g and finally the treatment (M) with only P.redivivus average weight 0.0011g. The use of bioencapsulation of Arthrospira (Spirulina) platensis in P.redivivus, presented an acceptable result compared to the already used Artemia Salina.Attribution-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nd/3.0/br/AquiculturaBetta splendensPanagrellus redivivusNutriçãoAquacultureBetta splendensPanagrellus redivivusNutritionbachelorThesis
