Some Physiological Responses of Clarias gariepinus Fed Graded Levels of Cirina forda Larvae Based Diets

The study examined the growth performance, hematological and digestive enzymes of Clarias gariepinus juveniles fed Cirina forda meal (CFM) based diets in the laboratory for a period of 10weeks. Five iso-nitrogenous (30%) experimental diets were formulated at various levels of CFM inclusion levels of 0% (control), 10%, 20%, 30%, 40% and 50%, designated as diets Q, A10, B20, C30, D40 and E50 respectively. Fish fed the CFM based diets showed mean weight gain (MWG), specific growth rate (SGR) and protein efficiency ratio (PER) comparable to the control diet. There was significant differences in the digestive enzyme activities of the fish as the CFM level in the experimental diets increased. Protease and maltase activities significantly increased, with diet C30 recording the highest maltase activity (4.37) while the cellulase and glucanase activities of the fish significantly (P0.05) between the PCV and RBC of the blood of the fish fed the various diets. Highest RBC (2.75 x106/µL) was obtained in fish fed the control diet while the lowest (2.55 x106/µL) was recorded in the fish fed diet E50. The White Blood Cell count and the Neutrophils of the fish fed the trial diets were not significantly higher (P>0.05) than those of the fish fed the control diets. From the results of this experiment, it is concluded that up to 50% inclusion level of Cirina forda meal in the diet of Clarias gariepinus was tolerable for good growth and physiological well-being of the fish

Awareness and Compliance to Library Rules and Regulations by Undergraduate Students in Two University Libraries in Southwest Nigeria

Abstract The study investigated awareness and compliance to library rules and regulations by the undergraduate students in Ladoke Akintola University and Obafemi Awolowo University libraries in both in south-western Nigeria. The objectives of the study were to find out the awareness of the undergraduates to the rules and regulations in university libraries, the categories of rules and regulations, the compliance level of the undergraduate students to the existing rules and regulations, the effects of the rules and regulations on library usage as wells as sanctions for defaulting the library rules and regulations. The study adopted a descriptive survey design and random sampling technique was used to select one hundred and fifty respondents in the university libraries. Questionnaire was used for data collection while descriptive statistics was used in analyzing the data. The undergraduate students in LAUTECH and OAU are aware of the rules and regulations in the university libraries and they comply with them very often. The study therefore recommends that: more awareness programmes on the rules and regulations should be created in the university libraries, users should be educated on the need to always comply with the library rules and regulations, stricter measures should be put in place to sanction or penalize any defaulter of library rules and regulations as this will further ensure compliance to the rules and regulations
