The ever-increasing population and hence higher demand for fish and other aquatic organisms for human consumption and exports have accorded greater priority to the aquaculture subsector. Therefore, there was need to conduct research to unveil facts relating to practices adopted by farmers in rearing fish and other aquatic organisms. This study emphasized concepts and importance of aquaculture, some common breeds of fish cultured, systems of aquaculture practices and methods of rearing fish and other aquatic organisms. The study also discussed eco-friendly aquaculture practices ensure sustainable fish production. The study further discussed the benefits of adopted eco-friendly aquaculture practices and constraints encountered by aqua-culturists. The study recommended among others that government should ensure proper training of extension workers who would in turn educate fish farmers on eco-friendly practices. The study also recommended that for expansion of aqua-cultural enterprises, government should provide more funds and liberalize land acquisition procedures to avail more land. Finally, the study recommended that requisite guidelines and regulations should be enforced to ensure that only practices that are sustainable and eco-friendly be adopted in the production of fish and allied products.

Illumination due to artificial lights on nesting beaches and from nearby place to nesting beaches is detrimental to sea turtles because it alters critical nocturnal behaviors specifically, their choice of nesting sites and their return path to the sea after nesting. Illuminations perplex the hatchlings to find sea after emerging. Numerous studies conducted in other countries have demonstrated that artificial lights negatively impact on turtles, both female adults as they come to and go from their home beach to lay eggs, and to turtle hatchlings as they seek out the way to the open ocean. In this study we correlated the mass nesting intensity of 5years (2012 to 2018) at Rushikulya mass nesting site to the illumination zone. Illumination due to light conditions on nesting beaches are complex, and measuring light pollution in a way that effectively captures the impacts to sea turtles is difficult. But increase in intensity of illumination on selective mass nesting beaches showed gradual reduction in intensity of preferred nesting site during the mass nesting event. A gradual shift of nesting preference was also observed more toward darker zone.

This paper deals with the integration of migrant children in informal communication networks in four diffenrent schools in Germany. The basic assumption is that these networks can serve as an indicator for the networking and embedding that take place within the class community and therefore can be used to investigate the integration of pupils with a migrant background. The initial results of our network analytical study reveal that the pupils with a migrant background are well integrated into the class networks. The study discloses that the migrant background does not serve as a conclusive characteristic of the pattern of class networks. The pupils are more or less networked with each other regardless of their migrant background, though it did emerge that children and adolescents born abroad, in particular, are far more likely to have outgoing relationships that remain unreciprocated.

The article examines the extent to which Vera’s The Stone Virgins can be read as a historiography of post-independence Zimbabwe. Some scholars accuse Vera in The Stone Virgins for fanning tribal friction, polarizing the nation and subverting the official war narrative. Our primary purpose is to explore the text to foreground the subtle discursive strategies as the text comments on the national historiography of Zimbabwe as a postcolonial nation-state. The article attempts to ascertain whether the textual narrative is ‘like the sun’, whether the text candidly offers alternative narrative by way of ‘writing in’ the elided aspects of the postcolonial experience (telling it blunt), or it subtly negotiates for the right to remember, heal and belong (telling it slant). The present article is therefore guided by two objectives, that is, to explore whether Vera’s The Stone Virgins can be regarded as historiography of post-independent Zimbabwe and also to examine whether the novel negotiates for closure and healing or simply opens up old wounds to fan social strife and polarity.

Advancement in the field of Information Communication Technology (ICT) has led to creation of new technologies, one of such is Over-The-Top technology. This new technology offers low-cost delivery of digital information content and services which includes VoIP services, instant messaging services and so on to consumers. The Over-The-Top services do not have a network system of their own but instead rely on of telecommunication operator networks and other Internet Service providers for the delivery of their services, without any policy or lease agreement with these operators. This work focuses on considering the perspectives of the regulatory board, the telecommunication operators and the consumer has it relates to this technology. We also analyse the impact of the Over the Top technology has on the Nigerian economy also.

The pursuit for quality in the learning process in Distance Higher Education is ongoing and continually leading to better ways in which to facilitate learning. It is evident in current literature that high-quality learning outcomes can be achieved by giving students in higher education institutions greater control over their own learning and by engaging in reflective inquiry and enhanced critical thinking within a constructivist paradigm. In the era of open access and digital-based information and communication in which we live, a huge challenge facing higher education is the issue of unethical practices by students. Ensuring academic honesty is a major challenge for traditional classroom teaching, but it is even a more pressing problem for online course-work in which students submit for example, individual assignments and projects. How can unethical student practices be eliminated where the use of information technology is manifest for all learning and instruction? Academically dishonest behaviour in Distance Higher Education (DHE) institutions is on the rise and manifests in various ways including inter-alia, plagiarism in which students use the work of others and which they fail to disclose through acceptable citation methods or even fail to acknowledge. Many find it expedient to cheat and may even stoop to bribery. There are also instances where students fabricate information and falsify what they present as the fruits of their own labours. Whether in assignments or portfolio work, or other such activities and assessments online, there are cases in which students either offer, or acquire assistance from other parties in their formal academic activities, falsify information, are guilty of misrepresentation and thus act out-of- line from an ethical perspective and demonstrate that they are devoid of ethical practice. It is thus crucial to integrate academic ethics education in all core programmes so that students and also their lecturers’, become conversant…
