Abstract

The purpose of the research is to determine giving Artemia nauplius and microworms affects the growth and color of guppy (Poecilia reticulata) fish fry. Three treatments were used in triplicates using a completely randomized design in this research. P1 (100% Artemia nauplius); P2 (50% Artemia nauplius and 50% microworm); and P3 (100% microworm) were the three treatments. Analysis of variance was applied to analyze the findings at a 95% confidence level. Further analysis is done using Duncan's Multiple Range Test if the results suggest a significant difference. The results showed that giving Artemia nauplius and microworms did not affect the survival rate of guppy fry. The provision of 100% microworms resulted in absolute growth based on weight and length of 0.12 ± 0.01 g and 1.26 ± 0.07 cm, respectively, specific growth rates based on weight and length of 6.24 ± 0.14%/day and 2.02 ± 0.08%/day, respectively. and the highest increase in color quality, which was 3.33 ± 0.12, so it can be concluded that the provision of 100% microworms resulted in increased growth and color quality in guppy fish fry .

Abstract

The high price of feed is caused by the high price of fish meal as a raw material for protein-source of feed. Black Soldier Fly (BSF) larvae have good nutrient content, so they can be used as an alternative raw material for feed. This research aims to determine the effect of fish meal substitution with fresh BSF larvae on the growth performance of tilapia (Oreochromis sp.). The research was designed using a completely randomized design with four treatments in the form of fishmeal substitution with BSF larvae and triplicates, including P1 (0%), P2 (25%), P3 (50%), and P4 (75%). The average weight of individual fish used was 17,98±1,49 g with a stocking density of 20 fish tank-1 and kept for 60 days in fiber tanks measuring 50x50x60 cm3. Feed is given as much as 3% of the fish biomass with a frequency of giving twice per day at 08.00 am and 15.00 pm. The data were analyzed using analysis of variance with a significance level of 95%. If there is a significant difference, further testing is carried out using Duncan's Multiple Range Test. Water quality data were analyzed descriptively. The research results proved that fresh BSF larvae could replace fish meal by 75% (P<0,05). Substitution of fish meal with fresh BSF larvae as much as 75% resulted in absolute growth rate based on length of 6,16±0,38 cm, absolute growth based on weight of 53,41±10,40 g, specific growth rate based on length of 0,10±0,01 % day-1, weight-based specific growth rate of 0,89±0,17% day-1, feed conversion ratio of 1,13±0,14 and feed efficiency of 89,71±10,81%.

Abstract

Maggot Black Soldier Fly (BSF) is a nutritionally rich alternative food for fish. The slow digestibility requires the combination with other technologies to produce fish with excellent growth. This study aims to investigate the impact of probiotic application on the growth, microbiome, and gene expression in the intestines of tilapia-fed black soldier fly (BSF) larvae. Tilapia intestines were examined after two months of rearing with three replications and two treatments: A) 30% maggots and 70% commercial pellets with probiotics, and B) 30% maggots and 70% commercial pellets without probiotics. We discovered that probiotics have a significant impact on the gut microbiomes of fish and their absolute growth. The amplicon sequence variant in the probiotic treatment (A) was 25, with dominance by Cetobacterium, Acinetobacter, Enhydrobacter, and Gemmobacter, while the non-probiotic treatment (B) was 8, with dominance by Cetobacterium and Turicibacter. The probiotic treatment increased the expression of Ghrelin, Muc-2, IL-1β, and I-FABP genes, but not the CD36 gene. These findings suggest oral probiotics can help boost tilapia production when fed maggot black soldier fly (Hermetia illucens).

Abstract

Graphical Abstract Highlight Research 1. Synbiotic diets increased intestinal mucin-2 expression without affecting systemic pro-inflammatory genes (IL-1β and TNF-α). 2. Prebiotic, probiotic, and synbiotic treatment significantly increased non-specific immune responses, such as respiratory burst, phagocytic activity, and plasma protein levels. 3. Prebiotic-fed fish exhibited the greatest weight gain and protein efficiency, indicating better nutrient utilization. 4. A synbiotic cocktail (Bacillus tropicus PCP1, Lactococcus garvieae JAL37, and inulin) reduced mortality after Streptococcus agalactiae challenge, indicating its potential application for early disease prevention.   Abstract Aquaculture of red hybrid tilapia (Oreochromis sp.) has been constrained by outbreaks of Streptococcus agalactiae disease. The application of prebiotics, probiotics, and synbiotics has shown potential in modulating host immune responses. This research investigated the effects of probiotic, prebiotic, and synbiotic supplementation on immune-related gene expression, non-specific immune responses, and resistance to Streptococcus agalactiae in red hybrid tilapia. Fish were fed experimental diets supplemented with probiotics (Bacillus sp. PCP1 and Lactococcus sp. JAL37 at 10⁷ cells/g), prebiotic inulin (5 g/kg), and synbiotics for 2 months, in three replicates. The results showed that only the synbiotic treatment increased intestinal mucin-2 gene expression, while all treatments enhanced non-specific immune responses through increased respiratory burst activity, phagocytosis, and total plasma protein. The highest growth performance was observed in fish receiving prebiotic supplementation. In the Streptococcus agalactiae challenge test, probiotic and synbiotic supplementation delayed the onset of mortality until day 4 post-infection. The study concluded that dietary prebiotic, probiotic, and synbiotic supplementation differentially reprogrammed innate immune gene expression in the intestine of red hybrid tilapia, leading to distinct immune responses, increased early resistance to Streptococcus agalactiae infection, and enhanced fish growth. A synbiotic comprising Bacillus sp. PCP1, Lactococcus sp. JAL37, and inulin is advisable to serve as a health management tool prior to immunization.
