Efficacy of various concentrations of synthetic hormones on the induced breeding of Channa marulius (Sole)

Journal of the World Aquaculture Society, Volume 54, Issue 1, Page 143-155, February 2023., 2023
Abstract A study was conducted to determine the artificial breeding response, embryonic and larval development of giant snakehead, Channa marulius, with the application of various dosages of stimulatory hormones: Suprefact® (LHRH) agonist and Ovaprim® (GnRH + dopamine inhibitor). First and second hormonal dosages of Suprefact® (diluted) and Ovaprim® (0.

Effect of stocking density in plastic boxes without oxygenation on the transport of pirarucu, Arapaima gigas (Schinz, 1822)

Journal of the World Aquaculture Society, Volume 53, Issue 5, Page 1031-1041, October 2022., 2022
Abstract For the evaluation of the effects of the transport density of pirarucu juveniles, 210 juvenile pirarucus, Arapaima gigas (488 ± 26.5 g) were randomly distributed in 12 plastic boxes at transport densities of 98, 146, 195, and 244 g L−1. The transport was carried out on a paved highway for 4 h, and at the end of the transport, all were returned

The Amazon river is a suture zone for a polyphyletic group of co‐mimetic heliconiine butterflies

Ecography, Volume 44, Issue 2, Page 177-187, February 2021., 2021
The Amazon basin contains few obvious geographic barriers, yet it is the most biodiverse region on Earth. One hypothesis to explain its diversity is that the very large rivers promote allopatric divergence. Consistent with this, maps of heliconiine butterflies made from museum specimens show high subspecies richness close to the Amazon river ...
