“…These results are consistent with previous studies on freshwater species such as Nile tilapia [53], grass carp, and African catfish [54], B. subtilis possesses the capacity to improve the breakdown of nutrients in the gut, resulting in increased energy availability for fish growth. Previous studies have demonstrated that probiotics can generate a diverse array of exo-enzymes and enhance the functioning of the digestive enzymes within the gut [55]. Furthermore, the inclusion of dietary probiotics can have an impact on the composition of the intestinal microbiota in fish.…”

The present study investigated the potential role of Bacillus subtilis as probiotic in striped catfish (Pangasius hypophthalmus). Fish (initial weight = 150.00±2.63g n = 180) were stocked in circular tanks. Four isonitrogenous (30%) and isolipidic (3.29%) diets were formulated having supplementation of B. subtilis at four different levels (P0; 0, P1: 1×106, P2: 1×108 and P3: 1×1010 CFU/g). Each treatment had three replicates, while each replicate had fifteen fish. The trial started on second week of July and continued for eight weeks. Growth, feed conversion ratio, crude protein content, the concentration of amylase and protease, the profile of both dispensable and non-dispensable amino acids in all four dietary groups increased with a gradual increase of B. subtilis in the diet. At the end of growth experiment, fish in all four groups were exposed to Staphylococcus aureus (5×105 CFU/ml). After S. aureus challenge, fish fed with B. subtilis responded better to damage caused by reactive oxygen species and lipid peroxidation and better survival rate. The catalase and superoxide dismutase level also increased in response to bacterial challenge in B. subtilis fed groups. On the other hand, the concentration of malondialdehyde gradually decreased in these groups (+ve P0 >P1>P2>P3). It is concluded that supplementation of B. subtilis as a probiotic improved the growth, protein content, antioxidant response and immunocompetency against S. aureus in striped catfish. The optimum dosage of B. subtilis, at a concentration of 1×1010 CFU/g, resulted in the most favorable outcomes in striped catfish. This single bacterial strain can be used as an effective probiotic in large scale production of aquafeed for striped catfish. Future studies can investigate this probiotic’s impact in the intensive culture of the same species.

“…Ketika larva beralih dari mengonsumsi makanan alami ke pakan buatan, larva harus terlebih dahulu menyesuaikan (menyapih) untuk membiasakan makan makanan buatan dan mencernanya dengan baik. Larva ikan kakap (Dicentrarchus labrax) yang terlalu dini diberi pakan buatan mikropartikulat yaitu pada hari ke-15 memiliki pertumbuhan dan sintasan yang rendah (Suzer et al, 2011). Menurut (Amornsakun et al, 2005), larva ikan betok mulai mengkonsumsi pakan buatan pada umur 16 hari, dan (Yulintine et al, 2012) menyarankan untuk memulai pemberian pakan buatan pada hari ke 25 setelah menetas berdasarkan perkembangan sistem pencernaan.…”

Penelitian untuk mengetahui pengaruh pakan buatan yang diberikan pada umur yang berbeda dilakukan pada larva ikan Betok Anabas testudineus Bloch. Studi ini terdiri dari lima perlakuan dan tiga ulangan. Larva mendapat terapi pakan yang sama dengan perbedaan awal pemberian pakan buatan pada hari ke-15, ke-20, dan ke-25 setelah menetas (masing-masing W15, W20, dan W25). Artemia (AR) dan pakan buatan saja (MD) diberikan pada larva pada perlakuan kontrol sampai akhir penelitian (35 hari setelah menetas). Larva ikan yang berumur lebih dari 10 hari dibesarkan di 15 akuarium dengan volume masing-masing 10 liter, masing-masing menampung 10 L-1 ikan. Larva ikan berumur 10 hari dipelihara pada 15 akuarium (volume 10 liter) dengan kepadatan 10 ekor L-1. Pengaruh pemberian pakan buatan mikrodiet pada larva ikan Betok (A. testudineus) pada umur yang berbeda menunjukkan pertumbuhan yang tidak berbeda nyata pada umur 20 dan 25 hari setelah menetas berdasarkan nilai rasio DNA:RNA. Sedangkan yang diberi mikrodiet sejak awal memiliki rasio DNA:RNA tertinggi yang diduga menunjukkan kondisi stres fisiologi karena terhambatnya perkembangan saluran pencernaan.

“…This disparity arises from different methodologies used in analyzing data, particularly in the collection of digestive tract secretions from other vertebrates (Assan et al, 2022). Examining the presence and activity levels of digestive enzymes provides valuable insights into food acceptance, the rate of fish larvae development, digestive efficiency, and ultimately, survival rates (Suzer et al, 2008). Research, such as that undertaken by Solovyev et al (2014), demonstrates that analyzing the activity of et al, 2015) digestive enzymes in fish offers valuable understanding of their role in ecosystems and feeding habits under natural conditions.…”

“…These enzymes are released into the intestinal tract, increasing the overall pool of enzymes. As a result, they break down food nutrients, making them more accessible to the host fish through the resulting metabolites they secrete (Wang, 2007;Suzer et al, 2008;Zhou et al, 2009). Research on fish digestive health has substantially contributed to understanding nutrient digestion, absorption, and utilization (Table 1) (Burns et al, 2016;Yan et al, 2016;Nie et al, 2017;Smith et al, 2017).…”

“…Scientists suggest that a key way probiotics benefit organisms in cultivation is by enhancing their nutrition through the generation of extra digestive enzymes. This leads to improved feed efficiency, accelerated growth, and the mitigation of intestinal disorders and antinutritional factors (Verschuere et al, 2000;Suzer et al, 2008). Following transit through the stomach, probiotics multiply within the intestine and utilize diverse carbohydrates to support their growth, while also producing vital digestive enzymes including lipase amylase, and protease (Suzer et al, 2008), by adding additional enzymes to those naturally produced by the host, the overall levels of digestive enzymes in the host's gut are increased.…”

There has been a surge of research in the aquaculture industry investigating probiotic, prebiotic, and synbiotic interventions on the physiological mechanisms of fish, specifically digestive enzymes, oxidative stress, and antioxidant defense. In fish, probiotics have been shown to improve nutrient utilization and growth performance by stimulating digestive enzymes. Meanwhile, probiotics, prebiotics and synbiotics have also been studied for their ability to modulate oxidative stress and antioxidant defense mechanisms in fish, highlighting their multifaceted health benefits. This review identified current trends, research gaps, and future considerations in this evolving field. Although promising findings have been made, a significant research gap exists in understanding the specific role of probiotics prebiotics, and synbiotics in modulating digestive enzymes, oxidative stress, and antioxidant defense systems in a variety of fish species. As this study investigate into the existing body of literature, it becomes evident that while certain aspects of these interactions have been elucidated, a nuanced and comprehensive understanding still needs to be discovered. The variations in experimental design, species-specific responses, and the lack of standardized methodologies contribute to the complexity of the field. Digestive physiology and antioxidant defense mechanisms vary among different fish species, so future research should focus on species-specific responses to probiotic, prebiotic, and synbiotic formulations. It will also be possible to establish robust correlations between dietary interventions and observed effects through a systematic experimental design and methodology approach. Accordingly, further research is needed to understand the interactions between probiotics, prebiotics, and synbiotics in fish and digestive enzymes, oxidative stress, and antioxidant defense. Identifying research gaps and adopting standardized methodologies can help develop tailored strategies to optimize aquaculture fish health and growth performance.
