Properties of Mean Value Sets: Angle Conditions, Blowup Solutions, and Nonconvexity [PDF]

open access: yesarXiv, 2018
We study the mean values sets of the second order divergence form elliptic operator with principal coefficients defined as $$a^{ij}_k(x):= \begin{cases} \alpha_k \delta^{ij}(x) &x_n>0 \beta_k \delta^{ij}(x) &x_n<0. \end{cases}$$ In particular, we will show that the mean value sets associated to such an operator need not be convex as $\alpha_k$ and ...

Effects of Dietary Supplementation of Coenzyme Q10 on Growth Performance, Biochemical and Physiological Attributes of Rainbow Trout (Oncorhynchus mykiss)

open access: yesVeterinary Medicine and Science, Volume 11, Issue 3, May 2025.
Coenzyme Q10 plays a crucial role in the electron transport chain and ATP production in the inner mitochondrial membranes. As a feed additive, it improves feed conversion ratio, specific growth rate and carcass crude protein while reducing the hepatosomatic index in rainbow trout.

Improving winter production of Nile tilapia: What can be done?

open access: yesAquaculture Reports, 2020
Despite being a tropical species, Nile tilapia is farmed in many subtropical regions worldwide, including southern Brazil, China, and Egypt, where production is hindered during the colder months of the year.

Gelatinisation of starch in Nile tilapia feed

open access: yes, 2015
The aim of study was to observe the effect of different levels of starch gelatinization in feed for Nile tilapia. Wheat was extruded with different moisture addition (20%, 25%, 30% and 35%), to tentatively obtain different degrees of starch gelatinization.

On-farm trials with rice fish cultivation in the west Kano rice irrigation scheme, Kenya [PDF]

open access: yes, 2006
The viability of integrating rice farming with fish culture was studied in ten (10) rice plots. The on-farm research was done during one rice-growing season starting May 2003.

Toxicity of Malathion to Nile Tilapia Oreochromis Niloticus (Linn.) Fingerlings

open access: yesScience Diliman, 1993
The toxicity of a commercial grade malathion on Nile tilapia, Oreochromis niloticus, fingerlings was determined. The 24, 48, 72, and 96-h LC50 of malathion on Nile tilapia fingerlings were 7.19, 5.43, 5.34, and 5.30 mg/l, respectively. Behavioral changes

Genomics of an ancient sex chromosome in Tilapia. W633 [PDF]

open access: yes, 2012
We have developed important genomic tools and methods of comparative genomics in the Nile tilapia, Oreochromis niloticus. The physical comparative map generated with BACs allowed us to calculate that there were about one rearrangement of intra ...

Polyculture of European seabass and Nile tilapia in the recirculating aquaculture system with brackish water: Effects on the growth performance, feed utilization, and health status

open access: yesAquaculture and Fisheries
Non-traditional aquaculture practices are crucially needed to overcome the climate change consequences, especially in countries suffering from water shortages.
