The growth of aquaculture sector is strongly dependent upon the continuous supply of inexpensive fish feed with balanced nutritional profile. However, fish meal (FM) is unable to satisfy this demand due to its scarce supply and high cost. In order to test the potential of cottonseed meal (CSM) as a fish meal replacer, a feeding trial of 12 weeks was conducted to check growth performance and proximate composition of Labeo rohita fingerlings. The protein ration of the test feed was satisfied by replacing FM with CSM at 0, 25, 50 and 75%. Sixteen test diets viz., TD1 (control), TD2, TD3, TD4, TD5, TD6, TD7, TD8, TD9, TD10, TD11, TD12, TD13, TD14, TD15 and TD16 were supplemented with citric acid (CA; 0 and 2.5%) and phytase (PHY; 0 and 750 FTU/kg) in a completely randomized design with 3×3 factorial arrangement. The highest weight gain (11.03g), weight gain% (249.21%), specific growth rate (1.39) and best feed conversion ratio (1.20) were recorded by fish fed with TD12. Furthermore, the same level increased the crude protein (59.26%) and fat (16.04%) being significantly different (p<0.05) than that of control. Conclusively, the addition of acidified phytase (CA; 2.5%, PHY; 750 FTU/kg) in TD12 (CSM=50%) led to the improved growth and proximate composition of L. rohita fingerlings.

Fish protein is serving as a source of nutrition for protein starving world. However, sustainable aquaculture products require inexpensive plant by-products due to finite sources of fish meal. Therefore, this study was conducted to examine nutrient utilization, growth performance and hematological indices of Cirrhinus mrigala fingerlings fed on Moringa oleifera leaf meal (MOLM) based diets. Fish were fed with six isonitrogenous and isoenergetic diets having MOLM as a substitute of fish meal (FM) at the levels of 0%, 10%, 20%, 30%, 40% and 50% for the period of 90 days. Fingerlings having initial weight 6.35±0.04g were reared in triplicate tanks at the stocking density of 15 and hand fed at the rate of 5% of total biomass twice regularly. Chromic oxide inclusion level was 1% in diets. After analysis, maximum growth performance and improved digestibility of nutrients were found in fish fed with diet at 10% replacement level as compared to fish fed on control diet and other test diets. Additionally, it was found that the red blood cells, white blood cells, hemoglobin and mean corpuscular hemoglobin concentration of fish showed a significantly (p<0.05) inverse correlation with the increase in MOLM. In present research, it was concluded that MOLM has good potential to be used as a FM substitute in C. mrigala diet with maximum effect at 10% showing positive hematological indices.

Present research was designed to understand the connection between metacognitions and obsessive-compulsive symptoms, with guilt sensitivity as moderator in people suffering from obsessive compulsive disorder (OCD). A positive association among metacognitions, guilt sensitivity and obsessive compulsive (OC) symptoms was hypothesized. Moreover, guilt sensitivity would significantly play the role of moderator in the connection of metacognition and obsessive-compulsive symptoms. The research was carried out in two phases. Phase 1 comprised of translation of Guilt Sensitivity Scale (GSS, Perdighe, Cosentino, Faraci, Gragnani, Saliani, & Mancini, 2015) in Urdu by forward-backward translation method. In phase 2, sample of the study consisted of 105 OCD patients. Sample was recruited through purposive sampling technique. Metacognitive Questionnaire (MCQ-30) by Wells and Cartwright-Hatton (2004), GSS by Perdighe et al., 2015 and Obsessive-Compulsive Symptoms Checklist (OCSC) by Jabeen and Kausar (2010) was used. Findings of the study revealed that there is a significant positive relationship in metacognitions, guilt sensitivity and OC symptoms. Furthermore, results revealed guilt sensitivity moderated with positive beliefs, cognitive self-consciousness, and uncontrollability/dangerousness of metacognitions in OC symptoms. It was concluded that people using more metacognition and with heightened guilt sensitivity were found to have more severity of OC symptoms. Keywords: Guilt sensitivity, Metacognitions, OC symptoms.
