“…These results are in agreement with the results observed by AGIUS & ROBERTS (2003) in teleost fishes where the presence of MMCs is due to the active phagocytosis period. These changes may be attributed even to age, sex and species of animals evaluated (DABROWSKA et al, 2012).…”

“…Increased hepatocyte proliferation may indicate pathogenesis resulting from toxicological factors (Dabrowska et al, 2012) or improper dietary composition . Lower numbers of PCNA-positive nuclei were observed in fish fed EFA-enriched Artemia, suggesting that the fatty acid profile of the provided live food was adequate to the feeding requirements of the larvae and thus did not lead to unnecessary, reparative hepatocyte proliferation (Ostaszewska et al, 2013).…”

The aim of this study was to compare the physiology and morphology of the digestive tract of Russian sturgeon (Acipenser gueldenstaedtii) larvae fed Artemia sp. nauplii enriched or non-enriched with essential fatty acids (EFA). Physiology was evaluated by digestive enzyme activity analysis, while morphology was assessed with histological methods. The larvae were divided into two groups, in which fish were fed either pure Artemia sp. nauplii or Artemia enriched in EFA. Both groups had similar survival rates, but fish fed EFA-enriched Artemia displayed higher, body weight and length. At the end of the experiment (22 dph): 1) the activities of lipase and leucine aminopeptidase were similar in both groups; 2) the activities of trypsin, alkaline phosphatase and γ-glutamyltransferase were insignificantly higher in fish fed pure Artemia; 3) the activity of α-amylase was significantly higher in the EFA-enriched feeding group; 4) lower hepatocyte lipid vacuole diameters and hepatocyte proliferation were measured in the EFA-enriched group. Lipid accumulation was observed in the anterior intestine of fish fed pure Artemia on the 15 th and 22 nd dph. The epithelial turnover was significantly lower in the EFAenriched group, in the posterior intestine on the 15 th dph, but no differences occurred between the groups on the 22 nd dph, in either anterior or posterior intestine. In conclusion, the study revealed a positive effect of the EFA-enriched Artemia-based diet on the physiology and morphology of the digestive system of Russian sturgeon larvae.

“…Since there was no statistical difference between T1 and T2, it is suggested that the FAM prevents congestion hepatopancreatic tissue in infected animals. Several authors report that hepatopancreatic changes are associated with contaminants (Dabrowska et al 2012, Gutiérrez-Praena et al 2012.…”

“…On the other hand, infected animals (T3 and T4) showed an increase in these characters, evidencing the high cellular synthetic activity, probably associated with production of inflammatory cytokine or detoxification enzymes, as well the increase in volume of mitochondria and lysosomes (Strmac and Braunbeck 2002, Marchand et al 2006, Abdel--Moneim et al 2012, Dabrowska et al 2012, Gutiérrez-Praena et al 2012.…”

ABSTRACT.-Oliveira S.T.L., Veneroni-Gouveia G., Santos A.C., Sousa S.M.N., Veiga M.L., Krewer C.C. & Costa M.M. 2014. Ascophyllum nodosum in the diet of tilapia (Oreochromis niloticus) and its effect after inoculation of Aeromonas hydrophila. Pesquisa Veterinária Brasileira 34 (5) The objective of this study was to evaluate the effect of Ascophyllum nodosum brown seaweed meal (FAM) on the health of Nile tilapia submitted to inoculation with Aeromonas hydrophila. The experiment was conducted for a period of 40 days using 120 Nile tilapia fingerlings, with age of 40 days, distributed in 20 tanks. A diet including Ascophyllum nodosum seaweed meal at 20g.kg -1 and a control diet (without FAM) were provided which constituted the treatments. Thirty days after beginning the experiment, A. hydrophila was inoculated by bacterial inoculum diluted in sterile saline solution at a concentration of 10 6 CFU ml -1 . Except for the width, which was greater for the treatment with the provision of FAM (P<0.05), there was no influence on the performance parameters of the fingerlings, but the occurrence of lesions in animals inoculated with A. hydrophila and fed with FAM was lower and they also exhibited a decline in the lesions in a shorter period of time than the control group. FAM prevents hepatopancreatic congestion in infected animals. Ascophyllum nodosum brown seaweed meal reduced the number of lesions in fish in a shorter time when compared to the control group.
