Nile tilapia ( Oreochromis niloticus ) fingerlings were divided into twelve groups (2/treatment) and fed on one of six different diets containing soybean meal protein replaced by 0, 10, 20, 30, 40 and 50% protein of waterhyacinth ( Eichhorinia crassipes ) in one feeding experiment for 70 days. The experimental diets were pellets and fed at a rate of 3% of the live fish body weight for six days weekly. The feeding experiment was conducted in 12 glass aquaria (60x35x40cm) filled...

The efficacy of Bacillus probiotics in disease prevention and increasing yields. Bangladesh has about 5 million ha of inland water resources such as rivers, estuaries, natural and manmade reservoirs, ponds and floodplains. The major species cultured are Indian and Chinese carps, tilapia and pangasius. However, in recent years, tilapia production has increased and expanded faster than carps and pangasius. Over the last 15...

Nutrition of shrimp is an important consideration in health management of cultured vannamei shrimp. The extensive to semi-intensive and intensive farming of shrimp demands nutritionally complete feeds for successful culture. The use of nutritionally inadequate feeds for shrimps can result in reduced growth, less production, more stress, low survivals, nutritional deficiency syndromes, mortality, infectious diseases etc. The uses of a wide variety of natural compounds are capable to...

1 | INTRODUCTION White shrimp (Litopenaeus vannamei) is an important economic shrimp species cultured worldwide and has unique advantages in intensive culture system, such as rapid growth rate, and tolerance to a wide range of salinity and temperature (Xia & Wu, 2018; Zhou, Wang, Wang, & Tan, 2013). Fishmeal (FM) is commonly used as protein source for white shrimp. It has palatable taste and is an excellent source of nutrients because of its high protein level,...

Abstract Methionine (Met) is an important building block and metabolite for protein biosynthesis. However, the mechanism behind its absorption in the fish gut has not been elucidated. Here, we describe the fundamental properties of Met transport along trout gut at µmol/L and mmol/L concentration. Both electrogenic and unidirectional DL-[ 14 C]Met flux were employed to characterize Met transporters in Ussing chambers. Exploiting the differences in gene expression...

ABSTRACT Methionine is a key factor in modulating the cellular availability of the main biological methyl donor S-adenosylmethionine (SAM), which is required for all biological methylation reactions including DNA and histone methylation. As such, it represents a potential critical factor in nutritional programming. Here, we investigated whether early methionine restriction at first feeding could have long-term programmed metabolic consequences in rainbow trout. For this...

ABSTRACT This study aimed to assess macronutrient-specific energy utilisation efficiency (i.e., protein, lipid and carbohydrate) for growth in common carp (an omnivorous species) and barramundi (a carnivorous species) and to assess if species-specific differences exist in energy efficiency of digestible protein (dCP), digestible fat (dFat) and digestible carbohydrates (dCarb). This was achieved by conducting a feeding trial experiment on common carp and by re-analysing data of a...

Abstract A study was conducted to evaluate the effects of lowering dietary fishmeal (FM) and crude protein (CP) levels, while maintaining essential amino acid levels, on growth performance, body composition, muscle metabolic gene expression, and chronic stress response of rainbow trout, Oncorhynchus mykiss, with and without handling stress. Eight experimental diets (isocaloric) with a 4 × 2 factorial design were formulated to contain two levels of FM (20%, 5%) and four...

Introduction Aquaculture has become the fastest growing food-producing industry around the world; however, the production efficiency of aquaculture could be further increased through the development of nutritious and cost-effective alternatives to traditional and finite marine protein feedstuffs such as fish meal (FM) (Suarez et al. 2013; Katya et al. 2014). Numerous studies have been carried out to replace or reduce the inclusion level of FM and to identify promising...

In aquaculture, producers commonly rely on formulated feeds to ensure optimal growth, health and quality of the farmed animal. Fish meal and fish oil from wild fisheries have traditionally been major constituents of aqua-feeds as they are excellent raw materials from a nutritional point of view, but their supply is finite. Therefore feed ingredients other than fish meal are selected for their nutritive value, balance of amino acids, digestibility of proteins,...

Conclusion Response of juvenile Nile tilapia to 3 levels of dietary Met (0.77 %, 0.95 % and 1.15 %) and 4 levels of dietary Lys (1.2 %, 1.6 %, 2.0 %, and 2.4 %) were evaluated in 3x4 factorial design over a 56-d feeding trial. Data showed main effects of both Met and Lys as well as their interaction (Lys x Met) effects on the performance of tilapia. Looking at the interaction effects, it was evident that fish responded to Met levels, only when the Lys was...

Key Information Grass carp production is the largest finfish aquaculture industry in China, with an increasing volume of commercial feed production. This justifies the need to improve our understanding of the dietary nutrient requirements of this species in order to produce them more efficiently. Available data on the amino acid requirements of grass carp show high variability and do not cover the whole production cycle, especially for the market sizes produced in...

All the intestinal tracts of healthy aquatic animal contain lactic acid bacteria and other probiotics to assist with body function and immune growth. The intestinal tract is the body’s biggest immune organ. Those hosts that lack for a healthy microflora can rapidly die from infection. Hence these probiotics have a symbiotic effect with their hosts. Most of the animals in fisheries are oviparous or viviparous organisms. Unlike the terrestrial animals that acquired their bacteria from...
