Special Issue Information

Dear Colleagues,

There is an extensive scientific bibliography on the use of probiotics, plant essential oils, and other functional additives in aquafeeds. Diverse and well-documented advantages of using probiotics and other feed additives in aquaculture include improved welfare and immune response of aqua-cultured organisms, improved digestibility, feed conversion, and growth rate, and decreased environmental impact of fish farms.

Exploring the advantages of probiotics and other feed additives for aquaculture can help to overcome a number of obstacles to the sustainability of the global aquaculture industry. This Special Issue’s goal is to compile research papers that report on developments and progress in this field.

Particularly welcomed are papers that focus on antioxidant and immune responses, as well as methods for producing and administering probiotics and other feed additives to aquaculture organisms. Papers that elucidate the mechanism of the beneficial effect of feed additives are also welcome.

Prof. Dr. Cosmas Nathanailides
Guest Editor

Abstract

A 28 day feeding trial was conducted to investigate the growth performance, immune response and intestinal microbiota of laminarin (LAM) supplemented diets in juvenile largemouth bass (Micropterus salmoides). Four hundred and eighty fish (initial average weight: 0.72 ± 0.04 g) were randomly divided into four groups (40 fish per tank with three replicates in each group) Four diets were prepared with LAM supplementation at the doses of 0 (control), 5 g Kg⁻¹ (LL), 10 g Kg⁻¹ (ML) and 15 g Kg⁻¹ (HL), respectively. No significant difference in the specific growth rate (SGR) and hepatosomatic index (HSI) was observed in fish among the four groups, or in the lipid and ash content of fish flesh. In addition, fish in the LL group exhibited much higher antioxidant capacity (p < 0.05), while the diets with the inclusion of 5 and 10 g Kg⁻¹ LAM remarkably decreased the antioxidant capacity of fish (p > 0.05). Dietary LAM at the dose of 5 g Kg⁻¹ inhibited the transcription of interleukin-1β (il-1β) and tumor necrosis factor-α (tnf-α), while promoting the expression of transforming growth factor-β (tgf-β) in fish intestine. Moreover, the beneficial intestinal bacteria Bacteroide, Comamonas and Mycoplasma abundance significantly increased in fish from the LL group, while the content of opportunistic pathogens Plesiomonas, Aeromonas and Brevinema in fish of the HL group was substantially higher than the control group. Overall, the appropriate dose of supplemented LAM in the diet was 5 g Kg⁻¹, while an excessive supplementation of LAM in the diet led to microbial community instability in largemouth bass.

Abstract

Ornamental fish trade represents an important economic sector with an export turnover that reached approximately 5 billion US dollars in 2018. Despite its high economic importance, this sector does not receive much attention. Ornamental fish husbandry still faces many challenges and losses caused by transport stress and handling and outbreak of diseases are still to be improved. This review will provide insights on ornamental fish diseases along with the measures used to avoid or limit their onset. Moreover, this review will discuss the role of different natural and sustainable microbial feed additives, particularly probiotics, prebiotics, and synbiotics on the health, reduction in transport stress, growth, and reproduction of farmed ornamental fish. Most importantly, this review aims to fill the informational gaps existing in advanced and sustainable practices in the ornamental fish production. Full article
