Introduction: This study critically evaluates adherence to Pap test screening practices in cytology-based cervical cancer the state of Amazonas over a 10-year period. Materials and Methods: A retrospective analysis was conducted results cytological examinations (Pap test) State from 2013 2023. For this purpose, Brazilian public databases Cervical Cancer Information System (SISCOLO) (SISCAN) (from The Department IT Unified Health - DATASUS) were consulted. Results: There decrease number tests...
This study evaluated the growth (first phase) and feeding responses (second of juvenile mutton snapper fed four isonitrogenous isoenergetic diets with increasing levels soy protein concentrate (SPC) in substitution to fish meal (FM). The FM was replaced by SPC at 0% (basal diet, SPC000), 33% (SPC130), 57% (SPC214) 77% (SPC300). After 95 days rearing, SPC300 attained a significantly lower body weight (54.9 ± 13.2 g) compared those SPC000, SPC130 SPC214 (76.5 14.0 g, 73.9 13.8 g 70.5...
Adequate feeding protocols are extremely important for the technical and economic feasibility of fish production systems. Two rates, 3% 4% body weight per day (3%BW 4%BW), two frequencies, twice three times a day, were tested during 84 days at initial grow-out phase tambaqui (94.5 ± 6.4 g) in earthen ponds. No mortalities or difference growth between treatments observed trial. Total feed intake conversion ratio low fed 3%BW. Fat deposition carcass concentration glycogen lipid vacuoles...
Tambaqui (Colossoma macropomum, Cuvier, 1818) is the most economically important native freshwater fish species in Brazil. It can reach a total length of over 1 m and weight 40 kg. The displays clear sex dimorphism growth performance, with females reaching larger sizes at harvest. In aquaculture, production monosex populations selective breeding programmes has been therefore identified as key priority.In present study, genetic linkage map was generated by double digest restriction-site...
The objective of this work was to evaluate the performance Litopenaeus vannamei fed different levels (0, 25, 50, 75, and 100%) soybean protein concentrate (63.07% crude protein, CP) replace fish meal-by product (61.24% CP). study conducted in clear water fifteen 800 L tanks equipped with aeration systems, constant heating (29 ºC), daily exchange (30%). Each tank stocked 37.5 shrimp/m3 (3.03±0.14 g). Feed supplied four times a day, at 6% initial biomass, adjusted daily. After 42 days, weight...
Apparent digestibility coefficients (ADCs) of nine protein ingredients were determined for pirarucu Arapaima gigas , a Neotropical fish species with great aquaculture potential in the Amazon. ADCs crude protein, energy and dry matter by feces sedimentation cylindrical-conical tanks. Experimental diets composed 795 g kg -1 reference diet, 5 chromic oxide 200 following test ingredients: by-product meal, salmon poultry hydrolyzed feather meat bone blood soybean corn gluten meal feed. Blood feed...
A type of platform, known as a table, is now being used for mangrove oyster farming. In Fortim, Ceará, Brazil, this activity was begun in June 2000 and covers an area 50 m² overlying sand-clay substrate. The present study has the following main objectives: to identify catalogue ichthyofauna colonizing Crassostrea rhizophorae farming platforms; evaluate ecological aspects, such possible correlation between physical chemical variables water quality occurrence ichthyofauna; observe differences...
Pirarucu (Arapaima gigas) is an Amazonian carnivorous fish species with great aquaculture potential. The apparent digestibility coefficients (ADC) of corn, low-tannin sorghum, broken rice, defatted rice bran, and wheat bran were determined for juvenile pirarucu using a completely randomized block design (two time blocks two replications per block). We also evaluated the influence digestion on structure starch granules by scanning electron microscopy (SEM) feed faeces. ADC nutrients energy,...
This study aimed at optimizing the sedimentation method for stool collection in digestibility tests pirarucu. In first trial, juvenile fish (435.26 ± 10.80 g) received reference diet with chromium oxide to determine gastrointestinal transit time (GITT). second, were fed and two test diets (corn soybean meal) 15 days. The apparent dry matter, protein phosphorus coefficients (ADC) determined verify of acclimatization experimental diets. pattern was visually analysed on day 5 10...
Abstract Two feeding rates, 3% and 4% body weight per day (3%BW 4%BW), two frequencies, twice three times a day, were assessed during 84 days at the initial grow-out phase of tambaqui in earthen ponds. In completely randomized 2x2 factorial experimental design quadruplicates, 4,800 juvenile (94.5 ± 6.4 g) assigned to sixteen 300-m 2 No mortalities or difference growth between treatments observed trial. Total feed intake conversion ratio low fish fed 3%BW. Fat deposition carcass concentration...
The determination of nutritional requirements, based on diets administered in practice, considers physiological specificities and sustainability are essential to the development suitable aquaculture technologies for novel fish species. growth jundiá (Rhamdia quelen Quoy Gaimard) juveniles (31.54 ± 4.92 g) fed five comprising increasing levels digestible protein (DP: 24, 29, 34, 39, 44 %) energy (DE: 12.13, 13.39, 13.81, 14.64, 15.06 MJ kg−1) with DP:DE ratios: 20, 22, 25, 27, 29 g MJ−1,...
