Introduction The fish nutrition has advanced with the expansion of aquaculture in order to achieve better performance rates. Thus, diets should provide all the nutrients and energy as a way to optimize the fish development. Among the nutrients, the fatty acids are essential for growth and survival, as well one of the most important sources of energy. The fatty acids of the omega 3 family are not produced by the fish, requiring supplementation in...

Physiological stress is one of the main contributing factors of disease outbreaks and reduced performances in the production of tilapia. Compared to the production of land animals, there are only a limited number of practical and cost effective disease treatment methods for aquaculture. Therefore, good stress management practices are an...

The latest reports on aquaculture production in Mexico establish that there has been a considerable increase in this agro-industrial activity. This rebound in aquatic organisms production for human consumption originates due to each year more producers are interested in venturing into tilapia (Oreochromissp.) farming. According to official numbers, Mexico is the ninth largest tilapia producer worldwide, with the state of Chiapas being the largest producer in the country thanks to the large...

Hammermills and Roller Mills for Aquaculture Feeds Hammermills are commonly used for grinding a broad range of materials used in the production of aquaculture feeds. Since most species of fish, crustaceans, and shellfish have a very short digestive tract, they require a finely ground, highly processed feed in order to obtain good feed efficiency. Additionally, most immature and many adult specimens produced in the...

1. Introduction Poultry and fish are both increasing in popularity as protein sources in human diets. Fish consumption has increased by 122% between 1990 and 2018 [1] with an over 500% rise in aquaculture production globally over the same timescale. Salmon production is estimated to reach 2.7 million tonnes (MT) by 2021, compared to 0.8 MT in 2000 [2]. Similarly, poultry meat production is also increasing year on year and is predicted to have reached 137 MT in 2020 [1]. This...

The efficacy of a single cell protein (SCP) methanotroph (Methylococcus capsulatus, Bath) bacteria meal (FeedKind®, Calysta, Menlo Park, CA, United States), in Pacific white shrimp (Penaeus vannamei) diets was studied to determine growth performance, survival rate and disease resistance against Vibrio parahaemolyticus causing Acute Hepatopancreatic Necrosis Disease (AHPND). The growth trial was assigned in a completely randomized design (CRD) with four treatments and 5 replicates of...

1. Introduction In Nigeria today, despite the significant investment in commercial agriculture by the government, aid agencies, multilateral organizations and individuals, livestock production has not succeeded in meeting the protein demands in the country (Oluwatayo and Adedeji, 2019) [1]. The increasing human population in the country has indicated that the conventional forms of livestock production and artisanal fisheries which have been over-exploited will not be sufficient...

INTRODUCTION Among the essential amino acids (AA), L-arginine (ARG) is one of the functional amino acids in animals. ARG is a nutritionally very important and essential AA for fish, and is considered the fourth limiting AA in aquafeed. Most of fish species excretes ammonia predominantly through the gills, diffusing NH 3 or NH 4 (ammoniotelic animals). Therefore, unlike mammals, fish have a low hepatic activity of carbamoyl phosphate synthase III or ornithine carbamoyl...
