Ecological Factors and Diversification among Neotropical Characiforms
International Journal of Ecology, Volume 2012, Issue 1, 2012., 2012 Morphological and DNA sequence data has been used to propose hypotheses of relationships within the Characiformes with minimal comparative discussion of causes underpinning the major intraordinal diversification patterns. We explore potential primary morphological factors controlling the early diversification process in some Neotropical characiforms as

Exploring ecohydrology through the lens of local fishers in the Bolivian Amazon
Ecosphere, Volume 17, Issue 4, April 2026.Abstract The natural flow regimes of Andean‐Amazon tributaries play a vital role in sustaining their rich biodiversity and productive local fisheries, but ongoing and proposed alteration of river flow regimes by large dams threatens to negatively impact river ecosystems. Despite its importance, our understanding of how hydrologic variability influences

Aquaculture Research, Volume 2026, Issue 1, 2026.Aquaculture faces significant challenges, including water pollution and low productivity in traditional systems. Biofloc technology (BFT) offers a sustainable alternative by recycling nutrients and improving water quality. The present study assessed the efficacy of bioflocs enriched with the freshwater microalgae such as Chlorella sorokiniana and ...

Biochemical responses of matrinxa Brycon cephalus (Gunther, 1869) after sustained swimming
Aquaculture Research, 2006 Juvenile matrinxa, Brycon cephalus, were submitted to sustained swimming for 72 days at 1.0 body length s−1. Exercised fish (EF) grew more than non-EF and their feed conversion ratio (FCR) improved; haematological responses demonstrated a decrease in haemoglobin and mean cell haemoglobin contents and increase in the mean cell volume.

Aquaculture Research, Volume 2026, Issue 1, 2026.Mystus cavasius (locally known as Gulsha) is a commercially important catfish in Bangladesh, typically transported live in oxygenated polythene bags without anesthetics, often resulting in severe stress, injuries, and high mortality. This study evaluated the efficacy of clove seed aqueous extract (CAE) as a natural anesthetic at different ...

Aquaculture Research, Volume 2025, Issue 1, 2025.Milt cryopreservation facilitates native fish’s constant production of commercial interest. However, it can damage spermatozoa (sptz) due to the osmotic stress of diluents and low temperatures. This study compares spermatic quality in fresh (SF) and cryopreserved (CS) milt in B. amazonicus for 24 h, 1 month, and 3 months.
