Costa,Janaina de Paula da; Oliveira,Dalany Menezes; Marques,Diego Rodrigues; Monteiro,Antonio Roberto Giriboni; Costa,José Maria Correia da. ABSTRACT The aim of this study was to evaluate the acceptability of corn snacks containing different concentrations of powdered shrimp. Five snack formulations were prepared: the control (with no powdered shrimp), F1, F2, F3 and F4, with the addition of 2%, 4%, 8% and 16% powdered shrimp respectively. The raw materials were subjected to a process of thermoplastic extrusion in a single-screw extruder with 3 mm radial die. The snacks produced were evaluated for their centesimal composition, the mineral content was quantified and qualified, and the snacks then submitted to sensory analysis. The sensory parameters under evaluation were: flavour, aroma, colour, texture, overall acceptance, ideal shrimp taste and purchase intention, carried out by a panel of 107...

Netto,Sérgio. This study was elaborated to identify and describe the main links of the sea shrimp productive chain in the municipal district of Laguna, historically known as the main sea shrimp (Litopenaeus vannamei) production area in the State of Santa Catarina, Brazil. The study, held from April to July 2005, previously identified the local productive process through observation, interviews and bibliographical research. Afterwards, specific questionnaires were elaborated for each of the several segments connected to the local activity. A total of 90 interviews were conducted, intending to map out the procedures and functionality of the productive chain, from the necessary inputs for production to the moment of shrimp acquisition by final consumers.

Ten out of fifty fresh and refrigerated samples of shrimp (Litopenaeus vannamei) collected from retailers in Natal (Rio Grande do Norte, Northeastern Brazil) tested positive for Vibrio parahaemolyticus. The Kanagawa test and multiplex PCR assays were used to detect TDH and TRH hemolysins and the tdh, trh and tlh genes, respectively. All strains were Kanagawa-negative and tlh-positive. Antibiotic susceptibility testing was done for seven antibiotics by the agar diffusion technique. Five strains (50%) presented multiple antibiotic resistance to ampicillin (90%) and amikacin (60%), while two strains (20%) displayed intermediate-level resistance to amikacin. All strains were sensitive to chloramphenicol. Intermediate-level susceptibility and/or resistance to...

Mol. Biol. De Donato,Marcos; Ramirez,Raúl; Howell,Chris; Verginelli,Roberto; Orta,Tomás; Cabrera,Saúl; Mata,Enrique; Manrique,Ramón. We investigated the effects of family selection on the growth rates of four genetic lines of Litopenaeus vannamei, the Pacific white shrimp, from Venezuela. The mean family weight at selection was 16.79 g and the mean growth rate was 0.169 g d-1 at a mean age of 138 days. The mean growth rates per generation were 0.141 g d-1 for the parental generation (P0), 0.173 g d-1 for the F1 and 0.191 g d-1 for the F2. Survival varied from 83.3% to 94.4%. There were statistically significant differences between lines, with lines B and C, growing at higher temperatures and lower salinities, showing the fastest growth. Regression analysis between growth rate and age for each genetic line showed high r² values, but smaller than those shown between growth rate and...

Zootec. Belettini,Frank; Seiffert,Walter Quadros; Lapa,Katt Regina; Vieira,Felipe do Nascimento; Santo,Carlos Manoel do Espírito; Arana,Luis Alejandro Vinatea. ABSTRACT A life-cycle assessment was conducted during semi-intensive and super-intensive commercial cultivation of marine shrimp from December 2011 to June 2012, considering all phases from the preparation of the nursery to harvesting of the shrimp, to determine the carbon footprints of each process. Inputs and outputs associated to the production of 1 kg of shrimp were evaluated using the CML-1A baseline method, V3.01 EU25, with Software SimaPro® 8.0.2, to identify the factors of impact that are most relevant to the category global warming, measured in kg of CO2 eq. The grow-out phase contributed the most to the final results in super-intensive culture, which had a higher carbon footprint, 47.9967 kg of CO2 eq., which was 1.0042 kg of CO2 eq. in the...

The effects of adding two different types of phosphatidylcholine (PC) (purified from soybean lecithin, SPC, or marine fish roe, MPC) on growth, survival and osmotic stress resistance as well as lipid and fatty acid composition of postlarval <i>Penaeus vannamei</i> was determined. PC was added at a level of 1.5% in a semi-purified diet containing similar levels of essential fatty acids (EFA). A PC-free diet served as the control treatment. The supplementation of 1.5% SPC significantly improved growth and reduced sensitivity to osmotic stress. <i>P. vannamei</i>-fed MPC showed inferior growth compared to those fed SPC, but yielded better growth and survival than the PC-deprived shrimp. The addition of any of the PC types resulted in a...

A study was conducted to evaluate variations of digestive enzyme activities in Litopenaeus vannamei (Boone) reared in commercial ponds under semi-intensive conditions. Shrimp were collected at each body weight increase of 2 g. As the shrimp grew (2-12 g), significant increases in the activities of lipase and chymotrypsin were observed. The total protease activity decreased from 6 g onwards. Trypsin activity showed a peak at 6 g and amylase activity increased two-fold after 2 g. Additionally, the stomach contents were analysed microscopically for shrimp between 2 and 10 g. Plant matter contributed above 30% of the total stomach content in 6-, 8- and 10-g shrimp.
