Developing a commercially relevant Atlantic cod aquaculture industry will require improvements in feed sustainability. Camelina oil and meal are potential replacements of fish oil and fish meal in aquaculture feeds. Camelina oil is high in 18:3ω3 (30%), with an ω3/ω6 ratio > 1. Camelina meal has a considerable crude protein level (38%), which includes significant amounts of methionine and pheny...

The purpose of this research was to analyze effect the balancing lemuru fish oil and palm on carcass broiler chemical composition breast broiler. 200 broilers reared from DOC 35 days old. Broilers were divided into 4 treatment groups 5 replications. consisted of: P0 = diet with 3% crude oil, P1 1% + 2% P2 P3 oil. Data analyzed using ANOVA Duncan's significant difference test. Treatment up had (...

As a climate change assessment criterion, carbon footprint CO2 equivalent (CF, CO2e) is used to evaluate the sustainability of aquaculture in terms its contribution greenhouse gas emissions. In this study, three-year CF rainbow trout production with cage farming project capacity 49 tonnes/year was calculated. The average farm for three years 52.72 %. Total expended summation on feed, general ma...

The study aimed to evaluate fish meal substitution with black soldier fly larvae supplemented 2% Trichoderma culture on female grower performance and carcass traits quail. materials used were 200 two-week-old quails an average body weight of 51.5 ± 7.3 grams. a completely randomized design five treatments four replications. were: BSF0 (100% meal), BSF25 (75% + 25% BSF BSF50 (50% 50% BSF75 (25% ...

To evaluate different methods of estimating bovine carcass composition, seventy yearling bulls of the "Asturiana de los Valles" beef breed were slaughtered and their carcass composition estimated by a commercial dissection of the right half-carcass and by tissular dissection of the 6th and 10th rib of the left half-carcass. Correlation and regression analyses were used to identify the most accu...

Aiming at finding cheaper and still efficient feed for aquaculture species 56 days feeding trial was conducted on African catfish (Clarias gariepinus) post fingerlings, fed five diets with a 40% crude protein target in which maize replaced offal meal 0%, 25%, 50%, 75%, 100% respectively. Ten fish each were stocked plastic aquarium tank containing 20 L of water. The 5% body weight divided into t...

The melanocortin-4 receptor (MC4R) plays a critical role in homeostasis and the regulation of body weight. Polymorphisms mc4r gene have been discovered linked to growth, carcass composition, meat quality traits. Therefore, we used CRISPR-Cas9 system target most important freshwater aquaculture species USA, channel catfish, Ictalurus punctatus. Guide RNAs were designed direct Cas9 coding sequenc...

Restoration is frequently aimed at the recovery of target species, but also influences the larger food web in which these species participate. Effects of restoration on this broader network of organisms can influence target species both directly and indirectly via changes in energy flow through food webs. To help incorporate these complexities into river restoration planning, we constructed a m...

The tilapia industry has grown significantly. Much waste is generated by the industry due to the fact that only the myomere muscles are removed and sold for human consumption. This portion constitutes approximately 36% of the entire fish, leaving 64% of the fish as waste lost during the various processing operations. This waste from the tilapia processing plant has the potential of being an alt...

1. Pacific salmon and steelhead once contributed large amounts of marine-derived carbon, nitrogen and phosphorus to freshwater ecosystems in the Pacific Northwest of the United States of America (California, Oregon, Washington and Idaho). Declines in historically abundant anadromous salmonid populations represent a significant loss of returning nutrients across a large spatial scale. Recently, ...
