Abstract

The primary line of defense against pathogens from the environment is often fish epidermis tissue. Nevertheless, little is understood about the physiological mechanisms that underlie the non-specific and/or specific protection that these cells can offer. The exact nature of the relationship between the evolution of ostariophysan fish club cells and chemical warning signals is still unknown and controversial. Fish epidermis layer cells comprise mucus cells, lymphocytes, macrophage cells, cuboidal and squamous epithelial cells, and cells specific to certain fish species. Club cells, also called "alarm cells," are chemical alarms that sound in the event of a potentially hazardous scenario. These cells will burst in the presence of a predator, releasing pheromones that, if the skin is physically damaged, trigger an avoidance and terror reaction. In sturgeon larvae, mucus cells were visible in week 1, but club cells did not appear until week 4. Due to their later development during ontogenesis and after wounding, club cells may not have as much of a protective effect during wound healing as filament or mucus cells. Club cells are mostly found in the epidermis of the skin, and it is thought that when they work in tandem with mucus and goblet cells to fight infections, they serve as the body's first line of defense.

Abstract

Fish productivity has long been the subject of studies using traditional Chinese medicine (TCM). To validate TCM's effectiveness on weight gain rate (WGR) and specific growth rate (SGR), a meta-analysis study was conducted. Of the 58 studies collected from PubMed, Scopus, and Cochrane Library, 4 eligible studies were analyzed quantitatively. The extracted data were then analyzed using Review Manager (RevMan) online to determine the standard mean difference (SMD), random effect, heterogeneity, and 95% confidence intervals (95% CI). As a result, TCM administration had a favorable effect on WGR (SMD = 8.33; p = 0.0001) and SGR (SMD = 8.12; p = 0.0004). In conclusion, this meta-analysis study emphasized the efficacy of TCM to improve fish production performance.

Abstract

Wing morphometry plays a crucial role in avian functional ecology, influencing flight performance, energy efficiency, and sexual selection. However, quantitative data on wing development in lovebirds (Agapornis fischeri), remain scarce. This study aimed to quantify and compare the growth of wing flexion width, wing extension width, and wingspan in male and female lovebirds at 4, 5, and 6 months of age to determine the onset and extent of sexual dimorphism. A total of 22 lovebirds (11 males and 11 females) were acclimatized under controlled environmental conditions and fed a millet-based diet. Wing measurements were obtained in accordance with animal welfare protocols using standardized morphometric techniques. Data were analyzed using Multivariate Analysis of Variance (MANOVA) followed by Tukey’s post hoc test at a 95% confidence level, and growth patterns were evaluated using linear regression analysis. Results showed significant (p < 0.05) sex- and age-related differences in all morphometric parameters. Males exhibited consistently higher mean values for wing flexion, extension, and wingspan at every age, with steeper linear growth slopes compared with females. The steady, positive correlation between age and wing dimensions indicates continuous and proportional development during the juvenile phase. These findings suggest that sexual dimorphism in wing morphology becomes evident as early as four months of age and intensifies with maturation. This study provides baseline trajectories of wing morphometrics in lovebirds, establishing reference standards that are valuable for avian biology, welfare, and sexing applications in psittacine species.

Abstract

This study presents a comprehensive gross anatomical and histological characterization of the alimentary tract in the fruit bat (Rousettus amplexicaudatus), a frugivorous megachiropteran species whose digestive morphology remains incompletely described. Seven adult bats (four males, three females) were captured in Banyuwangi, East Java, and examined through standardized morphometric, gross anatomical, and histometric analyses. Euthanasia was performed using Xylazine and Ketamine, followed by systematic dissection and measurement of body and visceral parameters. Histological preparations of the esophagus, stomach, duodenum, jejunum, ileum, and colon were stained with hematoxylin and eosin and evaluated microscopically. Results revealed minimal sexual dimorphism in external and internal morphometric traits, except for a significantly longer esophagus in males (p < 0.05). Gross anatomy showed a simple, glandular stomach and an elongated intestinal tract, consistent with adaptations for rapid carbohydrate digestion. Histomorphometric evaluation indicated comparable mucosal and muscular thickness between sexes, suggesting functional uniformity in digestive performance. Histological observations identified a stratified squamous esophageal lining, glandular gastric mucosa, prominent intestinal villi with crypts of Lieberkühn, and well-developed Peyer’s patches, highlighting efficient nutrient absorption and mucosal immune function. Overall, the findings demonstrate that fruit bat possesses a structurally specialized yet sexually consistent digestive system optimized for frugivory. This integrative dataset fills critical gaps in bat digestive morphology, providing a standardized anatomical and histological reference for comparative physiology, dietary adaptation, and host–pathogen interaction studies in megachiropteran bats.
