Natural Food Web in Farm Scale Models in Fish Aquaculture

Reviews in Aquaculture, Volume 17, Issue 3, June 2025.
ABSTRACT Bacteria and phytoplankton play an essential role in processing organic and inorganic waste nutrients, making the nutrients reutilized by higher trophic levels in an aquatic food web. Understanding the complex interaction between the microbial food web, nutrients, and cultured animals is crucial to achieving optimum production while minimizing

Long‐term interventions by conservation and development projects support successful recovery of tropical peatlands in Amazonia

People and Nature, Volume 7, Issue 4, Page 871-886, April 2025.
Abstract Rural communities in Amazonia rely on harvesting Mauritia flexuosa fruit, a dominant peatland palm, for their subsistence and income. However, these palms are felled to harvest the fruits, which has led to reduced resource availability due to the pressure exerted by the increasing fruit demand.

Extreme climate scenario and parasitism affect the Amazonian fish Colossoma macropomum

Science of The Total Environment, 2020
Global warming caused by greenhouse gases accumulation, in particular carbon dioxide, is the major current environmental challenge, as it will affect all life forms over the next decades. Aquaculture, a fast growing food production sector, is already facing the effects of global warming.

Assessment of Fruit Waste as Feed Additives in Aquafeed for Growth Performance and Health Benefits of Fishes Under Biofloc Technology

Reviews in Aquaculture, Volume 17, Issue 2, March 2025.
ABSTRACT The rising demand for fish and crustacean products has placed significant pressure on traditional aquaculture practices, which are increasingly unsustainable. Utilizing fruit waste as a feed ingredient in biofloc systems presents a promising solution for enhancing the sustainability and cost‐efficiency of fish farming.

Impacts of stocking on the genetic diversity of Colossoma macropomum in central Amazon, Brazil

Genetics and Molecular Research, 2016
Tambaqui (Colossoma macropomum) is the main fish species farmed on a commercial scale in northern Brazil. In view of the current scenario of Brazilian aquaculture, studies on the genetic improvement and reproductive management of captive tambaqui are crucial in identifying the genetic variability of broodstocks and devising management practices ...
