Land Distribution, Income Generation and Inequality in India's Agricultural Sector

Review of Income and Wealth, Volume 65, Issue S1, Page S182-S203, November 2019., 2019
This paper is a contribution to understanding income generation and inequality in India's agricultural sector. We analyze the National Sample Surveys of agriculture in 2003 and 2013 using descriptive and regression based methods, and estimate income inequality in the agricultural sector at the scale of the nation and its 17 largest states. We show that:

Earthworm (Eisenia Fetida) Meal as Fishmeal Replacement in the Diet of Oreochromis Niloticus (Linnaeus, 1758) Fingerlings

Aquaculture, Fish and Fisheries, Volume 5, Issue 4, August 2025.
ABSTRACT With the rising cost and ecological impact of traditional fishmeal, there is an urgent need for sustainable and locally available alternative protein sources in aquaculture. This study evaluated the effectiveness of Eisenia fetida meal as a sustainable protein substitute for fishmeal in the diets of Oreochromis niloticus fingerlings under ...

Utilization of the earthworm, Eisenia fetida (Savigny, 1826) as an alternative protein source in fish feeds processing: A review

Aquaculture Research, Volume 50, Issue 9, Page 2301-2315, September 2019., 2019
Abstract Use of fish meal in aquaculture is gradually becoming unsustainable due to competition, cost and ecological challenges hence the need to expand the alternative protein sources. The earthworm, Eisenia fetida is among the non‐conventional protein sources, which have been tested with relatively promising results, thanks to its high protein levels,

Earthworms use odor cues to locate and feed on microorganisms in soil. [PDF]

PLoS ONE, 2011
Earthworms are key components of temperate soil ecosystems but key aspects of their ecology remain unexamined. Here we elucidate the role of olfactory cues in earthworm attraction to food sources and document specific chemical cues that attract Eisenia ...

River Waste to Goldmine: A Tale of Floating Agriculture in Vulnerable Southern Regions of Bangladesh

Food and Energy Security, Volume 14, Issue 2, March/April 2025.
ABSTRACT Floating agriculture transforms marshy lands into productive resources, enhancing food security and rural incomes in climate‐vulnerable areas. While prior research highlights its potential as a climate‐resilient practice, gaps remain in understanding the determinants of adoption and long‐term livelihood impacts.

New insights into the reproductive physiology and culture approaches of Paratilapia sp., a Malagasy cichlid with potential interest for sustainable aquaculture

Journal of the World Aquaculture Society, Volume 56, Issue 1, February 2025.
Abstract One of the primary objectives in freshwater aquaculture is the search for sustainable systems based on agroecological intensification. In this context, the cultivation of local species is decisive, although requiring the identification of new candidates. Malagasy aquaculture is an example of the development of such an approach.
