Fishing through marine food webs [PDF]

Proceedings of the National Academy of Sciences, 2006
A recurring pattern of declining mean trophic level of fisheries landings, termed “fishing down the food web,” is thought to be indicative of the serial replacement of high-trophic-level fisheries with less valuable, low-trophic-level fisheries as the former become depleted to economic extinction.

Application evaluation of linseed oil as a substitute for fish oil in the commercial diet for juvenile Portunus trituberculatus

Aquaculture Reports, 2023
Vegetable oil (VO) is increasingly replacing fish oil (FO) in the commercial diet of crustaceans, partly due to a global shortage of FO. But little is known about how different amounts of substitution affect the health and metabolism of crustaceans.

DNA barcoding Indian marine fishes [PDF]

Molecular Ecology Resources, 2010
AbstractDNA barcoding has been adopted as a global bio‐identification system for animals in recent years. A major national programme on DNA barcoding of fish and marine life was initiated in India by the authors during 2006 and 115 species of marine fish covering Carangids, Clupeids, Scombrids, Groupers, Sciaenids, Silverbellies, Mullids, Polynemids ...

Dietary cholesterol promotes growth and ecdysone signalling pathway by modulating cholesterol transport in swimming crabs (Portunus trituberculatus)

Animal Nutrition, 2022
Cholesterol, as an indispensable nutrient, regulates molting and growth in crustacean. As crustaceans are unable to biosynthesize cholesterol de novo, it is central to understand how dietary cholesterol affects molting in crustaceans.
