Abstract

Understanding genetic variation among species is essential for effective selection and breeding enhancements. This study was conducted to assess the genetic diversity among three tilapia species (Oreochromis niloticus, Oreochromis aureus, and Oreochromis mossambicus) from several rivers located in South-South Nigeria. A total of 300 samples representing the three species were used for this research. Blood samples were collected from all individuals for DNA extraction, amplification, and sequencing of the mitochondrial (mt) control region. Analysis of mitochondrial DNA revealed that Oreochromis aureus exhibited the greatest number of polymorphic sites, with a total of 225, compared to Oreochromis niloticus and Oreochromis mossambicus, which had 129 and 84 polymorphic sites, respectively. The number of haplotypes was highest in O. niloticus with five, while O. aureus and O. mossambicus each had three haplotypes. O. niloticus also demonstrated the highest haplotype diversity (0.796), whereas O. aureus showed the highest nucleotide diversity (0.139). The largest genetic distance was found between O. aureus and O. mossambicus (0.388), whereas the smallest genetic distance was noted between O. niloticus and O. mossambicus (0.217). Enhancing tilapia production in Nigeria can be achieved by selectively breeding tilapia from the Itu, Ethiope, and New Calabar Rivers, which exhibited high genetic variation. [ABSTRACT FROM AUTHOR]

Abstract

Starch derived from two cassava cultivars, one with high amylose (TMS 92/0325) and the other with high amylopectin contents (TMS 91/02324), were screened for their ability to produce biodegradable plastics using different compositions of plasticizers and other materials. The rate of degradation of the bioplastics produced was equally evaluated. It was observed that the degradation values for bioplastics derived from TMS 92/0325 were 70.0%, 85.4%, 90.2% and 98.6%, while those from TMS 91/02324 were 72.4%, 86.6%, 93.5% and 99.2% at the end of 7 weeks for products containing 45%, 60%, 75% and 90% of starch, respectively. This is an implicit indication that the rate of degradability of the bioplastics produced from cassava does not depend on the level of amylose and amylopectin in the starch per se but rather on the amount of the starch itself that is used in the formulation. Moreover, our results equally demonstrated that bioplastics produced from the starch derived from cultivar TMS 91/02324 had a higher tensile strength than those gotten from cultivar TMS 92/0325. Taken together, these results are suggestive of the fact that though bioplastics produced from starch having a higher amylopectin level would have a higher tensile strength, however, they do not necessarily have a faster and greater rate of degradation when composted.Key words: Amylopectin, bioplastics, cassava starch, degradation, environment, sorbitol
