“…Microsatellites have been used for identification of escapees of the Oujiang color common carp, C. carpio var. color , in China [ 331 ], analysis of natural hybridization between two species of Andean pupfishes (Cyprinodontidae; Orestias agassizii and O. luteus ) mainly in the Lake Titicaca with implications for local fisheries, stocking and conservation [ 332 ], and identification of the occurrence and postulated hatchery origin of hybrids of Pseudoplatystoma corruscans and P. reticulatum in the Upper Paraná River, in South America [ 333 ]. However, modelling gene flow caused by escapees from a few farms simultaneously, revealed that changes detected in a wild population were lower when gene flow was simulated from one farm strain only [ 334 ].…”

A large number of species and taxa has been studied for genetic polymorphism. Microsatellites have been known as hypervariable neutral molecular markers with the highest resolution power in comparison with any other markers. However, the discovery of a new type of molecular marker—single nucleotide polymorphism (SNP) has put the existing applications of microsatellites to the test. To ensure good resolution power in studies of populations and individuals, a number of microsatellite loci from 14 to 20 was often used, which corresponds to about 200 independent alleles. Recently, these numbers have tended to be increased by the application of genomic sequencing of expressed sequence tags (ESTs), and the choice of the most informative loci for genotyping depends on the aims of research. Examples of successful applications of microsatellite molecular markers in aquaculture, fisheries, and conservation genetics in comparison with SNPs have been summarized in this review. Microsatellites can be considered superior markers in such topics as kinship and parentage analysis in cultured and natural populations, the assessment of gynogenesis, androgenesis and ploidization. Microsatellites can be coupled with SNPs for mapping QTL. Microsatellites will continue to be used in research on genetic diversity in cultured stocks, and also in natural populations as an economically advantageous genotyping technique.

“…The artificial production of interspecific hybrids consists in a classical method of genetic improvement for aquaculture programs [15]. Pintachara is a hybrid between catfish species, a female of Pseudoplatystoma corruscans (pintado) and a male of Pseudoplatystoma reticulatum (cachara) [16]. These hybrids have advantages in aquaculture compared to your parenting as better growing [17].…”

Salting is a traditional process to preserve food, while news species have been salted showing good results. However, salt accelerates lipid oxidation, influencing shelf-life of salted products. Using of antioxidants increases salted and/or desalted products shelf-life. Among the antioxidants employed in food industry spices have shown satisfactory results. In this work aqueous basil extract (Ocimunbasilicum) in pintachara salt was used. Pintachara is a hybrid of pintado and cachara (genus Pseudoplatystoma) whose flesh is much appreciated, being desirable to develop new product of this fish. The aqueous basil extract was used in a brine salt, and process was carried out with a control treatment. Samples were obtained during salting in 1, 14, 24, 36, 48 hours. In each sample period it analyzed moisture, water activity, salt content e TBARS. The aqueous basil extract interfered in salting processes and showed antioxidant action in this process. Practical applications: Brazilian consumers appreciate salted fish, as influence of Portuguese culture. There are some typical regional products, such as the pantaneiro cod, which consists on catfish from Pantanal that is salted as cod. The development of hybrids from native fishes in aquaculture leads to higher lipid content in the hybrids and the addition of natural antioxidants during salting process increases the product shelf-life and keeps the sensorial properties.
