| spatial population structure of the neotropical tiger catfish pseudoplatystoma metaense: skull and otolith shape variation. | using geometric morphometrics, the skull and otolith of tiger catfish pseudoplatystoma metaense were analysed to identify population structure in tributaries of the apure river (i.e. the sarare, caparo, guanare, portuguesa and san carlos rivers) in the orinoco basin, venezuela. the analyses show uniformity in skull and otolith shapes of p. metaense within and among four tributaries, with only the caparo river showing significant differences. within the apure basin, the stock of p. metaense was d ... | 2013 | 23639147 |
| [physical and chemical evaluation during refrigeration storage of salted catfish (pseudoplatystoma sp.) in brine solution, and packed under vacuum]. | salting fish in the south venezuelan towns are still the main method of preserving fish including cutt, and salting fish process, storage and commercialization. as the result, salted-dried fish is particularly susceptible to spoilage by a number of factors, including lipid oxidation, browning meat. packing salted fish product is an alternative increasing storage life time reducing lost of quality and enhancing the storage time. the present study evaluated the physic, chemist, and sensory quality ... | 2009 | 19719019 |
