This study examined the length-weight relationship and condition factor of Hydrocynus forskahlii (Cuvier, 1819) in River Yobe, Northeast, Nigeria. A total of 350 fish species were collected from commercial fishermen at four landing sites (Gogaram, Dogona, Bize, Azbak) within the study area between June to November 2020. The morphometric and meristic characteristics examined could be attributed to environmental variations (water temperature, stress, food availability, spawning ground, fishing intensity and sex). Monthly mean condition factor (1.19 ± 1.03) shows significant difference (P 0.05) during the sampling duration while highest mean condition factor was recorded in October (1.38 ± 1.15). Also change in weight of the sampled fish was caused by 77.4% change in length. A linear relationship was established with b value (1.2656) indicating a negative allometric growth pattern while correlation coefficient (r2 = 0.7775) indicated that LWR model is reliable. This study bridged literature gap on LWR and condition factor of Hydrocynus forskahlii in River Yobe, hence further research should be encouraged on the water body for sustainable utilization, decision making and policy formulation.

Principal component analyses were used to evaluate sexual dimorphism and the relationship among morphometric traits of Japanese quail (Coturnix coturnix japonica). A total of 153-day old quails (92 males and 61 females) were used in the study. The birds were housed in a wooden cage and fed ad-libitum. Data on body weight, body length, body girth, shank length, drumstick, wing length, keel length and shank length were obtained on a weekly basis using digital scale balance, measuring tape, and vernier caliper for a period of eight weeks. Principal component analysis was performed on the data obtained using the dimension reduction with factor analysis and morphometric traits were also correlated with body weight using SPSS statistical package version 21. Female birds had a significant higher (p0.05) body weight, body girth, drumstick, and wing length value than male counterpart, while no significant difference was observed for body length and shank diameter in both genders. A significant (p0.05) high and positive correlation coefficient was obtained between body weight and other linear measurements in both sexes. For both the male and female birds, one principal component was extracted, which explained 87.79 percent and 91.34 percent of the total variation observed in both species, respectively. . The principal components had its highest loading on keel length for both male and female Japanese quail and correlated highly with all parameters measured. Thus, the keel length could be used as selection criteria for improving body weight of Japanese quail.

Males and females broodstock of Clarias gariepinus (mean weight, 884.00±2.83g) were subjected to dietary supplementation of Cattle Stick (Carpolobia lutea) Leaf (CSL) at different inclusion levels of 0 (control), 0.5, 1.0 and 2.0% to evaluate the efficacy of the plant for growth performance and fertility enhancer. Clarias gariepinus broodstock (96) were allocated into 12 experimental fibre tanks at 8 fish per tank (4 males and 4 females) fed 40% crude protein at 3% body weight twice daily for 56 days. Each treatment was done in triplicate. Biological evaluation and reproductive indices were measured. There was significant difference (P0.05) in weight gained by fish fed experimental diets. Fish fed experimental diets containing CSL showed significantly higher (P 0.05) reproductive indices compared to the control diet. 0.5% inclusion level of CSL showed better performance in term of growth performance and reproductive indices and may be considered to be the best tolerance inclusion level for growth performance and fertility enhancer. The results of the study indicate that incorporating Cattle stick leaf diets in fish feed at 0.5% may have the potential for growth performance and fertility-enhancing agent in male and female C. gariepinus broodstock.Keywords: Clarias gariepinus, Carpolobia lutea leaf Growth, Reproductive indices, Broodstock

Susceptibility patterns of Escherichia coli to Veterinary Critically Important Antimicrobials (VCIAs) are poorly understood in most developing countries. We determined those patterns on n = 180 livestock fecal isolates from Chikomba district by disk diffusion method. Multiple Antibiotic Resistance (MAR) indices for the isolates were determined for risk analysis. Chi-square was used to test how antibiotic susceptibility level associated with animal species and farming scale. Resistance to Tetracycline and Ampicillin was high across animal species (above 70%). Moderate levels of resistance (30% to 54%) to Erythromycin, Trimethoprim and Chloramphenicol were detected across livestock species. Resistance levels were low (below 30 %) for Ciprofloxacin and Gentamicin. Resistance to Gentamicin, Tetracycline, Ciprofloxacin, Ampicillin, Chloramphenicol and Ceftazidime was associated with animal species (P ˂ 0.05). Antibiotic susceptibility patterns were independent of farming scale (P 0.05). Frequencies of isolates within each risk zone depended on animal species (P ˂ 0.05), contrary to farming systems (P 0.05). Multi-Drug Resistance was 73%, where most isolates were resistant to 5 antibiotics (23%) and none exhibited resistance to all antibiotics. Only 55% of isolates from cattle and over 80% from pigs and layers were within the high risk zone. Twenty nine of the isolates were extended spectrum beta lactamase (ESBL) positive. Higher ESBL frequencies (44%) were observed within Large Scale Commercial Farms (LSCF) followed by for Small Scale Commercial Farms (SSCF) (25%) and Resettlement farms (A1) (14%). Similarly, ESBL prevalence varied by livestock species (P 0.05), as follows: pig (39%), layers (32%) and beef (12%). Our study suggests high incidences of multi-drug resistance in livestock which need AMR surveillance strategies. Keywords: Antibiotic resistance, Pigs, Poultry, Beef cattle, Escherichia coli

This study investigated the effects of extruded pineapple pomace diet on growth and apparent digestibility coefficient of catfish (Clarias gariepinus). Four dietary extruded treatments of pineapple pomace Control (0%), T1 (10%), T2 (15%) and T3 (20 %) were fed ad libitum to catfish (21.05±0.04 g) for 60days. The final weight (53.52 - 57.45 g), weight gain (31.98 - 35.88 g) and feed conversion ratio (1.26 – 1.38) were relatively increased, while treatments up to 15% of pineapple pomace inclusion showed better performance. Fish survival rate (90.32 - 96.78%) showed significant difference. There were no significant differences (P0.05) in carcass composition among different dietary treatments. Apparent digestibility coefficient for crude protein, crude fibre and ash were highest in T2 (15%) and T3 (20%). The results indicated that pineapple pomace flour can be an ingredient in catfish diet for up to 20%. Key words: extruded; growth; apparent digestibility coefficient; carcass; proximate.

The climbing perch (Anabas testudineus) is an economically valuable freshwater fish. Relatively slow growth has been a challenge in the domestication of this species in Indonesia. Nutrition, including feed lipid content, is one factor affecting growth. This study examined the effect of enriching feed with fish oil on the growth and survival of climbing perch (A. testudineus) fingerlings. The research was carried out at the Water Quality and Aquatic Biology Laboratory, Faculty of Animal Husbandry and Fisheries, Tadulako University, Palu, Central Sulawesi, Indonesia from 17 December to 18 January 2020. A completely randomized design (CRD) was used with 4 treatments and 5 replicates. The fish oil feed enrichment treatments were: A (control, 0%); B (1%); C (2%) and D (3%). Water quality remained within the optimum range throughout the research period. Over the month, climbing perch absolute weight gain ranged from 2.4±0.981 g (A) to 3.4 ± 0.836 g (D), while growth in length ranged from 0.404±0.092 cm (A) to 0.504±0.071 cm (D); however, the differences were not statistically significant (P0.05). The survival rate of climbing perch over the one month study period was 100% under all treatments, indicating that basic nutritional needs were met. Enrichment of a commercial feed with fish oil (Scott’s emulsion) at rates of 1-3% did not provide a significant benefit in terns of climbing perch fingerling growth.
攀鲈(Anabas testudineus)是一种具有经济价值的淡水鱼。相对缓慢的生长一直是该物种在印度尼西亚驯化的一个挑战。营养，包括饲料脂质含量，是影响生长的因素之一。本研究探讨了鱼油富集饵料对攀鲈鱼苗生长和存活的影响。该研究于2020年12月17日至1月18日在印度尼西亚中苏拉威西岛帕卢塔杜拉科大学畜牧与渔业学院水质和水生生物学实验室进行。采用完全随机设计(CRD)， 4个处理，5个重复。鱼油饲料富集处理为:A(对照，0%);B (1%);C(2%)和D(3%)。在整个研究期间，水质保持在最佳范围内。月龄攀鲈的绝对增重范围为2.4±0.981 g (A) ~ 3.4±0.836 g (D)，体长范围为0.404±0.092 cm (A) ~ 0.504±0.071 cm (D);但差异无统计学意义(P0.05)。在1个月的研究期内，各处理对攀鲈的成活率均为100%，表明其基本营养需求得到了满足。在商业饲料中添加1-3%的鱼油(司各特乳剂)对鲈鱼鱼种的生长没有显著的好处。

Pigeon coccidiosis is caused by Eimeria spp; a protozoan parasite which limits birds’ productivity by causing severe illness. The current study was carried out to investigate the prevalence of coccidiosis on domestic pigeon in Libya. Intestinal contents of 100 pigeons (Columba livia domestica Gmelin, 1789) were collected within a period of five months; January to May 2020. The intestinal content was examined to detect of coccidian oocysts infection on the randomly selected birds. A total of 100 faecal samples were investigated with two methods;Willis-Schaafs (qualitative) and McMaster’s (quantitative). The results obtained showed that the number of infected Pigeons was 72 pigeons (72%) of the total number of Pigeons. The prevalence was higher in female than that of males, where the total of infected females was 50 (69.4 %) and infected males was 22 (30.6%). The results showed that the highest incidence of Eimeria labbeana was observed in the young pigeons than that of adults, where the total number of young pigeons was 66 (91.7 %), and adult pigeon was 6 (8.3 %).

The presence of the parasitic Hymenoptera plays a vital role in pest management for sustainable agriculture. So, it is crucial to know the parasitoid species that exist in an agroecosystem. Sweep Net, Yellow Pan Trap, and Malaise Trap are often used to study the diversity of Hymenoptera parasitic in agroecosystems. This study aims to see the effectiveness of Sweep Net, Yellow Pan Trap, and Malaise Trap in trapping Parasitic Hymenoptera. The study was carried out at four sub-districts, namely are Batang Tuaka, Keritang, Reteh, and Tembilahan Hulu sub-district. The research was carried out by sampling with the transect line method. Sweep net, Yellow pan trap, and Malaise trap have trapped 5,732 individuals of Parasitic Hymenoptera on tidal swamp rice in Indragiri Hilir Regency. The Parasitic Hymenoptera consists of 10 superfamilies, 30 families, and 320 morphospecies. Malaise traps are the best for trapping parasitic Hymenoptera on tidal swamp rice. Malaise traps have been able to trap up to 62% of morphospecies and 81% of the abundance of individual Parasitic Hymenoptera on tidal swamp rice. Yellow pan traps trap 28% of morphospecies and 15% of the abundance of individual Parasitic Hymenoptera. The sweep net can trap 10% of morphospecies and 4% of the abundance of individual Parasitic Hymenoptera.Keywords: Parasitic Hymenoptera; trap; tidal swamp rice.

Orange-spotted grouper is one of the coral reef fish has the economic value and exploited by local fisherman. Information about the size structure and sex ratio are urgent to formulate a policy for sustainability. This research aims to analyze the size structure and sex ratio of the orange-spotted grouper in Kwandang Bay. The research was conducted from December 2016 to November 2017. Sampling is carried out twice a month for one year. The total sample of orange-spotted grouper used for the analysis of the sex ratio was 149 individuals. Sample of orange-spotted grouper collected from fish landed and middlemen (grouper traders) at the Kwandang Fishing Port. Data analysis applying chi-square. The results show that males bigger than females. The sex ratio of orange-spotted grouper is 87.25 % female, 7.38 % male, and 5.37 % hermaphrodites. Orange-spotted grouper dominated by females and undergoes a gonad differentiation to male (protogynous hermaphrodite). It is concluded that The size of the male orange-spotted grouper is larger than that of the female grouper. The caught orange-spotted grouper is dominated by the female phase and undergoes a differentiation of the gonad from female to male (protogynous hermaphrodite)

The global criticism on the adverse effects of synthetic antibiotics including destabilization of gut microflora necessitated research into natural alternative like phytobiotics. Tamarind pulp is a phytobiotic known for its antimicrobial, growth-promoting and antioxidants properties, with little information on the mechanism of its growth promotion in fish. Therefore, this study investigated the effects of tamarind pulp (TP) meal as feed additives on the growth, gut microflora, and morphometry in Clarias gariepinus. The fish were fed with diets fortified with graded levels (0.0%, 0.5%, 1.0%, 1.5% or 2.0%) of TP or 0.2% oxytetracycline (OTC). Fish weight gain, feed conversion ratio (FCR), gut microflora and morphometry were determined. The weight gain of fish rose (P 0.05) with increasing levels of TP, while the FCR reduced significantly, compared to those fed the control diets. The total viable counts and enterobacteriaceae from the gut of fish fed OTC-fortified control diet was lower, compared the fish fed unfortified control (0.0% TP) diet and diets containing TP. Fish fed 1.0-2.0% TP-fortified diets had significantly higher yeast counts, compared to those fed other diets, while on the other hand higher (P0.05) Streptococcus sp was obtained from fish fed the control diets. The thickness of muscular lining of the base of villi, villi height and absorption area were higher (P ˂ 0.05) in fish fed OTC-fortified (C2) diet, compared to other treatments, while lower crypt depth were obtained in fish fed TP-fortified diets. The correlation analyses showed moderate negative (R = -0.539 at P 0.05) relationship between FCR and population of enterobacteriaceae while a very strong positive relationship (R = 0.848 at P 0.01) existed between FCR and population of haemolytic Streptococcus. The enhanced growth in fish fed TP-fortified diets could be accredited to the reduced crypt depth and colonization of yeast and reduced Streptococcus counts. Therefore the application of tamarind pulp meal at 2% is recommended for enhanced growth and healthy gut microflora composition.
