Abstract	Aquaculture is the fastest-growing agricultural industry in the world. Fishmeal is an essential component of commercial fish diets, but its long-term sustainability is a concern. Therefore, it is important to find alternatives to fishmeal that have a similar nutritional value and, at the same time, are affordable and readily available. The search for high-quality alternatives to fishmeal and fish oil has interested researchers worldwide. Over the past 20 years, different insect meals have been studied as a potential alternate source of fishmeal in aquafeeds. On the other hand, probiotics—live microbial strains—are being used as dietary supplements and showing beneficial effects on fish growth and health status. Fish gut microbiota plays a significant role in nutrition metabolism, which affects a number of other physiological functions, including fish growth and development, immune regulation, and pathogen resistance. One of the key reasons for studying fish gut microbiota is the possibility to modify microbial communities that inhabit the intestine to benefit host growth and health. The development of DNA sequencing technologies and advanced bioinformatics tools has made metagenomic analysis a feasible method for researching gut microbes. In this review, we analyze and summarize the current knowledge provided by studies of our research group on using insect meal and probiotic supplements in aquafeed formulations and their effects on different fish gut microbiota. We also highlight future research directions to make insect meals a key source of proteins for sustainable aquaculture and explore the challenges associated with the use of probiotics. Insect meals and probiotics will undoubtedly have a positive effect on the long-term sustainability and profitability of aquaculture.

Abstract	Land use changes are driving the fragmentation of natural habitats in Peninsular Malaysia, even within protected areas, which results in a loss of habitat connections. This process directly affects wildlife species, many of which are threatened with extinction, especially large mammals. To better conserve wildlife, these natural habitats must be linked both structurally and functionally. However, sparse data exists for this geographic region with regards to landscape connectivity and the connectivity importance of habitat patches, and this lack may hinder conservation efforts. To close this knowledge gap, we measured landscape connectivity and the connectivity importance of habitat patches in Selangor State of Peninsular Malaysia, and within its protected area system. We used two large mammals as focal species and graph-based connectivity indices (i.e., probability of connectivity) to map and develop a connectivity importance index (CII). Selangor has poor landscape connectivity for large mammals. CII showed only the two largest habitat patches in the study area have a high connectivity importance. All protected areas situated at hilly sites and those with less human interference yielded a high connectivity importance. However, large parts of habitat patches with a high connectivity importance are located outside the protected areas. These findings demonstrate the importance of considering connectivity indices for large mammals when planning protected area placement. Our study provides an approach to evaluate and plan for land conservation targeting wildlife, but also inform wise land use development.

Abstract	The aquaculture industry is looking for sustainable alternatives to conventional fish meals in fish feed, and insect-based meals are proving to be a promising solution. These meals are nutritionally optimal as they have a high protein content and an ideal amino acid profile. However, the presence of chitin, a component of the insect exoskeleton in these meals presents both an opportunity and a challenge. Chitosan, a derivative of chitin, is known to improve the physiological functions of fish, including growth, immunity, and disease resistance. While chitin and its derivative chitosan offer several physiological benefits, their presence can affect the digestibility of feed in some fish species, making the inclusion of insect-based meals in aquafeeds complex. While studies suggest positive effects, some problems, such as reduced growth rates in certain species, emphasize the need for further research on chitin digestion in fish. Chitinase, an enzyme that breaks down chitin, is being investigated as a potential solution to improve the nutritional value of insect meals in aquafeed. This review provides a comprehensive analysis of the applications, benefits, and challenges of using chitinase in aquaculture, highlighting the enzyme’s role in improving feed digestibility, disease control, and environmental sustainability. Extensive research is required to fully understand the potential of chitinase enzymes in aquaculture and to optimize their applications in this dynamic field. Overall, this review provides insight into the evolving landscape of insect-based meals and the applications of chitinase enzymes within sustainable aquaculture practices.

Abstract	Turkey bird is one of the popular poultry species which is reared primarily for meat production and considered as one of the major sources of animal protein. With such importance of this species, this study was designed to investigate the gross and histomorphology of the ovary and oviduct with especial emphasis on sperm-host glands of the turkey hen involving ten mature female turkeys (Meleagris gallopavo). The present study highlighted the distribution pattern of sperm-host glands (SHGs) in the oviduct of turkey hen that has a potential role in producing a fertile egg in poultry industries. The oviduct of turkey consists of the infundibulum, magnum, isthmus, uterus, and vagina which are sole distributors for making nutrition enriched egg. The tissue samples were collected from the ovary, different segments of the oviduct and especially uterovaginal junction (UVJ) and infundiomagnal junction of the oviduct. The ovaries and the oviducts were dissected and fixed in Bouins solution and processed for a light microscopic study. Histologically, the left ovary of turkey consisted of an outer cortex and inner medulla, with different stages of follicles. In all areas of the oviduct except the infundibulum and vagina, the tunica mucosa epithelium was lined with ciliated pseudo stratified columnar epithelium, and the lamina propria-submucosa contained branched tubular glands. Sperm-storage tubules were observed in the uterovaginal junction and infundibulo-magnum junction. These tubules were mostly branched, slightly coiled and extended into the lamina propria from the bases of the mucosal folds. These glands had proximal and distal parts; the proximal part was lined by pseudostratified columnar epithelium and distal part by non-ciliated simple columnar epithelium. The number of sperm host glands was more at uterovaginal junction than infundibulomagnal junction. The sperm-host glands might play a functional role in the storage and release of spermatozoa from the SHGs in response to oviposition or ovulation. The results ...

Abstract	The radiofrequency electromagnetic radiation emitted by smart phones on biological systems has wide media coverage and public concern in recent years. The aim of this study was to explore the effects of fourth-generation cell phone radiation exposure on hematological (Total leukocyte count, Total erythrocyte count, and hemoglobin %), biochemical (Serum creatinine) parameters, and histopathological changes in the kidney and testis of Swiss albino mice. A total of 30 male Swiss albino mice weighing 45–65 g was randomly divided into three groups (n = 10). The first group A was the control group, the second group B, was exposed to 40 minutes of mobile phone radiation daily, the third group C was exposed to 60 minutes of radiation daily from two 2400 Megahertz fourth-generation connected mobile phones for 60 days, respectively. The electromagnetic radiation frequency radiometer measured the frequency of electromagnetic radiation emitted from cell phones. The specific absorption rate was calculated as 0.087 W/kg. The control group was kept under similar conditions, but the electromagnetic field was not given for the same period. All the mice were sacrificed at the end of the experiment. The blood samples were collected for hematobiochemical study, and then kidney and testis tissues were collected for histopathological study. Results of the study showed that the body weight and total erythrocyte count values were significantly (p < 0.05) decreased while total leukocyte count, hemoglobin %, and serum creatinine values were significantly (p < 0.05) increased in both the radiation exposure groups relative to the control group. Histopathological observation showed the kidney of 60 minutes exposed mice interstitial inflammation that causes marked mononuclear cellular infiltration compared to the 40 minutes and control mice. Compared to control mice, histopathological examinations of testicular tissue from the exposed mice, showed irregular in shapes and non-uniform sizes and fewer spermatogenic cells layer that leads ...

Abstract	Land use changes are driving the fragmentation of natural habitats in Peninsular Malaysia, even within protected areas, which results in a loss of habitat connections. This process directly affects wildlife species, many of which are threatened with extinction, especially large mammals. To better conserve wildlife, these natural habitats must be linked both structurally and functionally. However, sparse data exists for this geographic region with regards to landscape connectivity and the connectivity importance of habitat patches, and this lack may hinder conservation efforts. To close this knowledge gap, we measured landscape connectivity and the connectivity importance of habitat patches in Selangor State of Peninsular Malaysia, and within its protected area system. We used two large mammals as focal species and graph-based connectivity indices (i.e., probability of connectivity) to map and develop a connectivity importance index (CII). Selangor has poor landscape connectivity for large mammals. CII showed only the two largest habitat patches in the study area have a high connectivity importance. All protected areas situated at hilly sites and those with less human interference yielded a high connectivity importance. However, large parts of habitat patches with a high connectivity importance are located outside the protected areas. These findings demonstrate the importance of considering connectivity indices for large mammals when planning protected area placement. Our study provides an approach to evaluate and plan for land conservation targeting wildlife, but also inform wise land use development.
