Sustainable biofuel production from fish processing waste: lipase‐catalyzed hydroesterification of tilapia residual oil

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Fishing waste and byproducts, whether naturally occurring or from industrial processing, are important sources of high‐value compounds. Fertilizers, biomaterials, cosmetics, biolubricants, and biodiesel are some of the substances that can be obtained from these residues. The objective of this study was to conduct a theoretical and experimental

Detection of tilapia lake virus (TiLV) infection by PCR in farmed and wild Nile tilapia (Oreochromis niloticus) from Lake Victoria.

open access: yesJournal of Fish Diseases, 2018
Tilapia lake virus disease (TiLVD) has emerged to be an important viral disease of farmed Nile tilapia (Oreochromis niloticus) having the potential to impede expansion of aquaculture production.

Induction of Male Courtship Behavior by Olfactory Cues Released From Ovulating Female in the Medaka, Oryzias latipes

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Chemical communication between males and females is important for successful reproduction of animals. The activation of male courtship behavior by female olfactory cues has only been demonstrated in a limited number of teleost species. In the present study, we showed that in the model animal medaka, courtship behavior in males are activated by

Toxicity of mercury (Hg) on survival and growth rate, hemato- and histopathological parameters ofOreochromis niloticus

open access: yesJurnal Akuakultur Indonesia, 2013
Heavy metals are serious pollutants of the aquatic environment because of their environmental persistence and ability to be accumulated by aquatic organisms. Oreochromis niloticus exposed to 0, 0.16, 0.5, and 1.0 ppm Hg for 30 days.

TRIVALENT CHROMIUM (CR+3) IN DIETARY CARBOHYDRATE AND ITS EFFECT ON THE GROWTH OF COMMONLY CULTIVATED FISH [PDF]

open access: yes, 2016
Trivalent chromium (Cr+3) is an essential trace mineral for fish bio-physiological functions. Researches on Cr+3 in the form of organic compound indicated that the mineral affected the bio-activity of insulin, the blood glucose influx, and subsequently ...

Water calcium concentration modifies whole-body calcium uptake in sea bream larvae during short-term adaptation to altered salinities [PDF]

open access: yes, 2014
Whole-body calcium uptake was studied in gilthead sea bream larvae (9–83·mg) in response to changing environmental salinity and [Ca2+]. Calcium uptake increased with increased fish size and salinity.

The impact of turbidity on foraging and risk taking in the invasive Nile tilapia (Oreochromis niloticus) and a threatened native cichlid (Oreochromis amphimelas)

open access: yesBehavioral Ecology and Sociobiology, 2020
Anthropogenic activity can increase water turbidity, changing fish behaviour by reducing visibility. The spread of invasive species is also facilitated by human activity, further increasing the pressure on native species.

Comparative Proteomics of Salinity Stress Responses in Fish and Aquatic Invertebrates

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Fluctuating salinity is symptomatic of climate change challenging aquatic species. The melting of polar ice, rising sea levels, coastal surface and groundwater salinization, and increased evaporation in arid habitats alter salinity worldwide. Moreover, the frequency and intensity of extreme weather events such as rainstorms and floods increase,
