... Fish diseases have a “stress-related” nature, whereas fish exposure to stressors will increase their susceptibility to infections. It was also noted that fish exposure to biotic and abiotic stressors would exaggerate the disease signs, elicit high mortalities, and cause severe economic losses. Motile aeromonad septicemia (MAS) is a major bacterial disease affecting a variety of finfish species thr ...

Abstract:
... The rapid expansion of the aquaculture industry, the global shortage of fish meal (FM) supplies from fisheries, and the continuous demand for FM as a primary protein source in aquafeed lead to increase the necessity to find new alternatives. Plant protein sources have gained significant importance among aquaculture farmers and nutritionists because of their availability, eco-friendly, sustainabili ...
... Nowadays, the application of immunomodulators in aquaculture has become of an urgent need because of high incidence of fish and shrimp diseases. For a long time, researchers have paid great interest to find suitable, relatively economical, and environmentally safe immunostimulant products to be used either as feed or water additives to boost immunity and increase the resistance of fish and shrimp ...
... The burbot (Lota L.) is one of the most promising freshwater new fish species for cold-water aquaculture. Due to the lack of availability of wild spawners, it is imperative to breed cultured spawners. In the present study, artificial reproduction of a cultured stock of burbot was carried out and then compared with wild fish reproduction results. Patterns of burbot final oocyte maturation were deve ...
... The aquaculture industry is still expanding to provide human beings with healthy and nutritious protein sources. Infectious diseases, deteriorated water quality parameters, and other environmental stressors are from the main obstacles that threaten fish farming and reduce its profitability. Vibriosis is one of the most common bacterial diseases that negatively affect shrimp, marine fishes, and som ...
... The current study was carried out to assess the effects of using Bacillus subtilis-fermented rice bran (FRB) on water quality parameters, water microbial counts, growth performance, body composition, antioxidants/oxidants, and immunity biomarkers of white leg shrimp (Litopenaeus vannamei) reared at different salinities. Shrimp juveniles (0.51 ± 0.11 g) were distributed in triplicates into 27 1-m³ ...

... In aquaculture, phytobiotics can be used as feed supplements with attractive growth-promoting, immunomodulatory, antioxidant, and several health benefits for a variety of finfish species. Herein, we evaluated of the impacts of milk thistle extract (MTE; Silybum marianum) on the overall performances of Pangasianodon hypophthalmus juveniles. Fish (7.10 ± 0.00 g) were fed on diets containing graded M ...

... Farmed fish and shrimp are continuously challenged by multiple stressors during their life stages, such as hypoxia, pH fluctuations, different salinities, high nitrite, un-ionized ammonia, injury during handling, inadequate nutrition, or food shortage, which can eventually adversely impact their health, welfare, and growth rates. Besides, these stressors can weaken production and decrease their re ...
... A sudden outbreak of disease associated with high mortality rates (75–85%) was reported in market-sized striped mullet (Mugil cephalus), farmed in earthen ponds in Manzala, Egypt, during the summer (July) 2019. We identified poor water quality parameters, including a sharp decrease in dissolved oxygen (DO) (3.5 mg/l) accompanied by elevated levels of unionized ammonia (0.90 mg/l), nitrite (0.05 mg ...
... This study was designed to evaluate the impacts of dietary supplementation with Ginkgo biloba leaf extract (GBL) on the growth, intestinal histomorphometry, immunity, antioxidant status, and expression of cytokine genes in Nile tilapia reared in the hapas. A control diet was enriched with different GBL levels (0.0, 5.0, 7.0, and 9.0 g/kg) to form 4 experimental diets and were fed to Nile tilapia f ...
... The present study examined the influences of dietary single strain (SSP; Lactobacillus plantarum) or multi-strain (MSP; Bacillus subtilis, L. plantarum, L. rhamnosus, L. acidophilus, L. delbrueckii) potential probiotics on Nile tilapia (Oreochromis niloticus) in biofloc (BF) and stagnant-renewal (SR) culture systems. Fish (8.63 ± 3.35 g) were allotted in six groups: T1, SR control; T2, SR + SSP; T ...

... Spirulina (Arthrospira platensis) (SP) has been utilized for a long time as a valued feed supplement because of its proteinous content and other beneficial phytochemical compounds. Herein, we investigated the influences of SP-supplemented diets on growth, body somatic indices, digestive enzymes, hepatic antioxidant activities, and immunological responses of hapa-reared thinlip mullet (Liza ramada) ...

Abstract:
... Pikeperch is one of the major new fish species in freshwater aquaculture. Artificial reproduction is difficult in this species, and many aspects require further study. These include synchronization of female maturation, latency time, gamete quality and spawner survival rate. For these reasons, many fish farmers must constantly replenish their spawning pikeperch stock, often with wild fish. Data on ...
... The shrimp industry has been greatly expanded in the past two decades in several countries throughout the globe to provide human beings with nutritious seafood and healthy protein. In this concern, shrimp farmers have tried to increase their production rates by intensifying shrimp in culture facilities. However, intensive farming may increase the possibilities of the entrance of emergent pathogens ...

A 56-day feeding experiment was carried out to investigate the influences of dietary organic selenium (OS) on the growth, body composition, serum biochemistry, stress responses, and immune indices of Nile tilapia reared under sub-optimal temperature. Fish (5.61 ± 0.5 g) were allotted in seven experimental groups (5 replicates per each) and fed on a basal diet supplemented with 0.0 (CTR), 0.1, 0.2, ...
... In aquaculture, nutrigenomics or “nutritional genomics” is concerned with studying the impacts of nutrients and food ingredients on gene expressions and understanding the interactions that may occur between nutrients and dietary bioactive ingredients with the genome and cellular molecules of the treated aquatic animals at the molecular levels that will, in turn, mediate gene expression. This conce ...
