Genetic divergence between Pseudoplatystoma corruscans and Pseudoplatystoma reticulatum (Siluriformes: Pimelodidae) in the Paraná River Basin.
Pseudoplatystoma corruscans (Spix and Agassiz, 1829) and Pseudoplatystoma reticulatum (Eingenmann and Eigenmann, 1889) are large migratory catfishes of high biological importance and great commercial value in South America. Because fertile crossbreeds can be artificially produced in hatcheries, a high genetic proximity between these two Pimelodidae species is conceivable. Possible escape of cro...
متن کاملDevelopment of a Quality Index Method (QIM) for Maatjes Herring Stored in Air and Under Modified Atmosphere
The aim of the study was to develop a Quality Index Method (QIM) scheme for maatjes herring stored in air and under a modified atmosphere at 4°C and 10°C. The attributes included in this new scheme are: appearance of skin side and bone side, color of the blood, odor (rancidity and other), taste (rancidity and other), aftertaste and texture. The QIM scheme developed proved to be potentially usef...
متن کاملCytogenetic mapping of H1 histone and ribosomal RNA genes in hybrids between catfish species Pseudoplatystoma corruscans and Pseudoplatystoma reticulatum.
A physical chromosome mapping of the H1 histone and 5S and 18S ribosomal RNA (rRNA) genes was performed in interspecific hybrids of Pseudoplatystoma corruscans and P. reticulatum. The results showed that 5S rRNA clusters were located in the terminal region of 2 chromosomes. H1 histone and 18S ribosomal genes were co-localized in the terminal portion of 2 chromosomes (distinct from the chromosom...
متن کاملCytogenetic characterization of F1, F2 and backcross hybrids of the Neotropical catfish species Pseudoplatystoma corruscans and Pseudoplatystoma reticulatum (Pimelodidae, Siluriformes)
The cytogenetic characteristics of Pseudoplatystoma corruscans and Pseudoplatystoma reticulatum and their F1, F2 and backcross hybrids were assessed by using chromosome banding techniques. The diploid number of 56 chromosomes was constant in all species and lineages, with a karyotypic formula containing 20 metacentric, 12 submetacentric, 12 subtelocentric and 12 acrocentric chromosomes. Nucleol...
متن کاملبررسی اندازه گیری تاز گی ماهی تیلاپیا با استفاده از روش Quality index method ( QIM )
تازگی ماهی با استفاده از جداول QIM از طریق حسی بر اساس امتیاز دهی به کلیه اندامهای ماهی در حال تغییر ( مثبت و منفی ) و در نهایت تبدیل پارامترهای کیفی به پارامترهای کمی و آنالیز آماری داده ها استوار است. در جداول استفاده شده نوسانات امتیازها از صفر تا 23 بوده و به ترتیب برای کیفیت عالی امتیاز از صفر تا 3 ، خوب از 3 تا 7 ، متوسط از 7 تا 10و از 10 به بالا غیرقابل قبول ارزیابی میگردد. در این بررسی ...
