| Some aspects of the biology and ecology (distribution pattern, feeding habits and length-mass relationship) of a population of Diamphipnopsis samali are studied in a first order stream surrounded by exotic forest located in North Patagonia, Chubut province, Argentina. Two samplings were performed during high and low water periods. All information was treated with fixed-effects 2-factor ANOVA models to assess significant differences. Mouth parts analysis of D. samali indicates that it corresponds to an intermediate type between carnivorous and herbivorous-detritivorous type. The guts content shows that the species specially fed on wood and fungal hyphae. No significant difference on the consumed food between sampling periods was found, even though there... |

| Feed transition of Steindachneridion scripta larvae was investigated using seven treatments in which the reference diet, Artemia spp. nauplii, was totally substituted for a 56% crude protein artificial diet in two-day intervals. Initially, all treatments were fed with Artemia spp. nauplii and, subsequently, during the transition period, feed was equally composed by Artemia sp. nauplii and artificial diet. Everyday, one of the treatments began the feed transition, which was implemented between the second and the eighth days of culturing. Two treatments were used as control: one exclusively fed Artemia spp. nauplii and another only with artificial diet. Total weight, total length, and survival rate were not influenced by the day in which feed transition was... |
