Fick’s Diffusion Laws and Scaling of the Gill Surface Area and Oxygen Uptake in Fish Open
The oxygen consumption of adult fish (Q) is proportional to their body weight (W) raised to a power, estimated as the slope (dQ) of a linear regression of log(Q) vs. log(W). Similarly, the gill surface area of adult fish (GSA) is proportio…

A review of the global use of fishmeal and fish oil and the Fish In:Fish Out metric Open
Aquacultured carnivorous species consume most of the world’s fishmeal and fish oil (FMFO), which itself is primarily derived from small pelagic fish. This has raised concerns about the practice’s impact on wild fish stocks, ecosystems, and…

The Relationship between Mean Length at Maturity and Maximum Length in Coral Reef Fish Open
This article proposes a mechanism that triggers first maturation and spawning in coral reef (bony) fish, which allows for predicting their length at first maturity. Thus, mean lengths at first maturity (Lm) and the corresponding maximum le…
