Journal of Applied Ichthyology, Volume 38, Issue 5, Page 479-486, September 2022., 2022 Abstract Increasing the number of fish stocked might optimize the efficiency of intensive aquaculture systems however at the same time might have a negative impact on fish welfare and growth parameters. In the current study, three different stocking densities were evaluated in duplicated tanks to investigate the effect of different stocking densities ...

The key mechanisms associated with the survival of Gulf toadfish, Opsanus beta, when in severe hypoxia. [PDF]
J Fish BiolAbstract Florida's shallow seagrass beds experience daily diurnal fluctuations in environmental oxygen, leading to hypoxic episodes (PO2 < 2 mg L−1, ~6 kPa) that have increased in frequency and intensity in recent decades. The native Gulf toadfish (Opsanus beta) have been shown to employ a suite of adaptive cardiovascular, ventilatory and metabolic ...

The conundrum of pharyngeal teeth origin: the role of germ layers, pouches, and gill slits
Biological Reviews, Volume 97, Issue 1, Page 414-447, February 2022., 2022 ABSTRACT There are several competing hypotheses on tooth origins, with discussions eventually settling in favour of an ‘outside‐in’ scenario, in which internal odontodes (teeth) derived from external odontodes (skin denticles) in jawless vertebrates. The evolution of oral teeth from skin denticles can be intuitively understood from their location at ...

Nitrate toxicity in Siberian sturgeon (Acipenser baeri)
Aquaculture, 2006 Abstract Excess nitrate in aquaculture has traditionally been reduced by water exchange. Current trends in environmental regulation, however, are limiting the amount of water which may be consumed or discharged, reducing the ability to use large influxes of water to remediate excess nitrate. This will create significant challenges for the aquaculture
