AI Article Synopsis
- Zebrafish were studied over 40 days to see how different diets (high vs. low frequency) affect bone health.
- Fish fed more frequently (3×/day) were larger in weight and length compared to those fed less often (2×/week).
- The frequent-feeding group had greater vertebral bone density but lower overall bone volume, while low-feeding fish had more signs of bone resorption in their scales.
- The researchers suggest that lower calorie intake might lead to higher leptin levels, which negatively impacts bone health in zebrafish.
Article Abstract
Zebrafish (Danio rerio) were fed high and low-frequency diets over 40 days to assess the effect of diet on bone parameters. Fish fed 3×/day (High) were significantly greater in total weight and length vs. fish fed 2×/week (Low; <0.01). The High group had significantly higher vertebral bone density (p = 0.0009) and lower bone volume (p = 0.04) compared to the Low group. Scales from the Low group also had higher density of resorption lacunae in their scales (p = 0.02). We interpret these data to hypothesize that higher leptin titers associated with reduced calorie intake is generally catabolic to bone in zebrafish.

Utility of integrated papyrus-bivalve for bioremediation of aquaculture wastewater.
Environ Sci Pollut Res Int

Department of Environmental Management, College of Agricultural and Environmental Sciences, Makerere University, P.O. Box 7062, Kampala, Uganda.
Aquaculture generates substantial amount of residual feeds and faecal matter that accumulate in the culture environment and pollute effluent-receiving water, diminishing its ecological functioning. To devise means of treating nutrient-rich aquaculture wastewater, the efficiency of integrated papyrus-bivalve mesocosms in removing nutrients was evaluated. The mesocosms were fed on water (6600 L) from one brood-stock pond and allowed to settle for 2 weeks.

Increasing aquaculture production requires high-density farming, which induces stress, necessitating supplements to mitigate its effects and ensure fish health. The aim of this study was to examine how CaNa2EDTA (EDTA) affects the growth, immune response and antioxidant activity in Nile tilapia (Oreochromis niloticus). The fish were raised at three different stocking densities: low (LD = 2.

Hydroxycinnamic acid derivatives are a class of phenolic acid compounds, including sinapic acid, ferulic acid, and caffeic acid, which are widely found in plants. This experiment was conducted to study the effects of hydroxycinnamic acid derivatives (sinapic acid, ferulic acid, and caffeic acid) on the growth performance, muscle physical parameters, and intestinal morphology of tilapia. A total of 320 tilapia fingerlings (9.

The present study evaluated the potential of Ashoka, Saraca asoca leaf meal (SLM), in carp diets following fermentative processing with a tannase-producing fish gut bacterium, Bacillus subtilis (KP765736). The processing of SLM led to a significant (P < 0.05) reduction in major anti-nutrients (tannin, trypsin inhibitor, and crude fiber), while crude protein content increased.
