Abstract
The objective of this study was to assess the impact of short-term fasting and subsequent re-feeding cycles on compensatory growth performance, blood glucose levels, and digestive enzyme activity in mono-sex juvenile Nile tilapia (Oreochromis niloticus) over a 60-day period. A total of 150 juvenile Nile tilapia (Avg. wt. 9.34 ± 0.97 g) were allocated into five treatment groups: a control group (continuously fed) and four fasting groups — T1 (1‑day fasting), T2 (3‑day fasting), T3 (5‑day fasting), and T4 (7‑day fasting). Re-feeding occurred for 7 days in each group immediately following the fasting period in a recurring cycle. The average weight gain, specific growth rate, and feed efficiency ratio significantly (p < 0.05) declined starting from the T3 group. Blood glucose levels during fasting significantly decreased starting from the T2 group, but after re-feeding, they returned to levels comparable to the control group. The liver glycogen levels significantly (p ≤ 0.05) decreased during fasting and completely recovered upon re-feeding, while muscle glycogen levels did not show any significant (p ≤ 0.05) changes throughout the experimental duration. The activities of the digestive enzymes amylase and lipase significantly (p ≤ 0.05) decreased during fasting starting from T1 and T2 groups, respectively, but after re-feeding, they returned to the levels seen in the control group. In contrast, the protease enzyme levels during the fasting period initially increased up to the T2 group and subsequently returned to control levels in the T4 group. The findings of this study indicate that only the groups that experienced very short fasting periods, specifically up to the T2 group, attained body weights like the control group upon re-feeding due to compensatory growth. Therefore, this study concluded that implementing up to 3 days of fasting followed by 7 days of re-feeding in multiple cycles can serve as a strategy for minimizing input costs in tilapia farming.

The Intersection of Justice and Urban Greening: Future Directions and Opportunities for Research and Practice

Abstract
The global uptake of green infrastructure in urban settings holds considerable promise for fostering both social and ecological benefits. Recognising the imperative to ensure equitable distribution of these advantages, this paper draws on the rich traditions of justice considerations within urban studies to inform research on urban greening. Focusing on three key trends — reconceptualising the ‘urban’ category, acknowledging the role of historical processes in shaping contemporary uneven and unjust geographies, and considering power dynamics in infrastructure development — we propose five tenets for advancing justice-focused urban greening research. These tenets encourage researchers to act as knowledge brokers, practice reflexivity, recognise the complex dimensions of justice which diversity of scale might reveal, embrace uncertainty, and cultivate a “modest imaginary” concerning infrastructure projects.

Abstract
Fifty years ago this week, Gaura Devi, an ordinary woman from a nondescript village in India, hugged a tree, using her body as a shield to stop the tree from being cut down. Little did she know that this simple act of defiance would be a seminal moment in the history of India and the world. Or that Reni village, where she lived, would come to be recognised as the fountainhead of the Chipko environmental movement. What the foot soldiers of Chipko wanted was an acknowledgement of their Indigenous rights to access forest resources that were crucial for their survival. What they got instead was a national law and a ministry populated by a new breed of power brokers — who, in the years to come, would decide at times that habitat preservation is possible only by keeping local communities out.
