“…Therefore, breeding warm water fish in BFT systems provides economics. The implementation of BFT systems in aquaculture is considered not only for food production but also for ornamental aquaculture (Yu et al 2020;da Cunha et al 2020;Besen et al 2021). In this context, goldfish (Carassius auratus) has high value with its interesting color and is one of the most popular ornamental species in the world (Sinha and Asimi 2007).…”

Biofloc technology (BFT) has become an agenda not only to meet the need for protein food but also for ornamental aquaculture with the increasing interest in sustainable aquaculture. In this context, the current study focused on BFT for ornamental goldfish (Carassius auratus), which has commercial value. In the study conducted with control and two different C/N ratios (15:1 and 20:1), nitrogen cycle occurred rapidly in BFT groups. On the other hand, increasing the C/N ratio had a positive effect on total suspended solids and total bacteria count in the culture water. In terms of growth performance, specific growth rate and weight gain were observed to be significantly higher at high C/N ratio. Feed conversion ratio showed lower results for the C/N 20 group. According to the liver histological results, the vacuolization symptom is more severe in BFT groups. Considering all the results, the suitability of C. auratuscultivation in the BFT system with a C/N ratio of 20 was proven according to nine different evaluation criteria. In conclusion, the cultivation of C. auratus in BFT systems is recommended both economically and ecologically.

“…Hatchery-produced seed meets demand, but hatcheries are more concerned with quantity than quality, and the spawn-to-fry yield ratio of these species is 3 : 1 in earthen ponds, with catla fry performance always being lower in terms of growth and survival [4][5][6]. Fish in the nursery stage are also often subjected to intensifcation which generally increases stress and subsequently susceptibility to infectious disease, hence requiring proper management to obtain optimum growth and survival [7,8]. Biofoc systems (BFTs) are a potential alternative strategy for the intensifcation of fsh larviculture which enhances immunity of the cultures.…”

“…Biofoc technology is studied for its application in nurseries as an additional feed source for postlarvae, to provide extra essential nutrients [9][10][11] and improve water quality to support better larval survival and growth [12,13]. BFT has been applied successfully in the nursery phase in diferent fsh and shrimp species such as Oreochromis niloticus [12], Rhamdia quelen [13], Clarias gariepinus [14], Labeo rohita [15][16][17], Carassius auratus [8], Farfantepenaeus brasiliensis [18], and Penaeus vannamei [19].…”

A 20-day 3 ∗ 3 factorial experiment was conducted in 100 L HDPE experimental tanks to investigate the effect of the C/N ratio (10, 15, and 20) and stocking density (3, 4, and 5 spawn L−1) on Gibelion catla spawn nursery rearing in the indoor biofloc system. Rice bran was used as the carbon source for manipulating C/N ratios. Each treatment was stocked with catla spawn of average length (6.7 ± 0.4 mm) and average weight (1.6 ± 0.2 mg). Water parameters showed that increasing the C/N ratio from 10 to 20 significantly ( p < 0.05 ) reduced total ammonia nitrogen (TAN) and nitrite nitrogen (NO2-N) and increased nitrate nitrogen (NO3-N) in the water. The insignificant difference ( p > 0.05 ) and lowest final average length, average length gain, average weight gain, and specific growth rate (SGR) were recorded in C/N ratios of 10 and 15 compared to a C/N ratio of 20. A significant difference ( p < 0.05 ) in survival was observed with the increasing C/N ratio. Increasing the fish stocking density resulted in higher mortality. However, a higher amount of fry produced was observed in the treatments with 3 and 4 spawn L−1. Crude protein content increased significantly ( p < 0.05 ) with the increasing C/N ratio with higher content in C/N 20. No significant difference ( p > 0.05 ) in proximate composition of biofloc was observed in different stocking density groups. In conclusion, the application of the biofloc technology with a C/N ratio of 20 at a stocking density of 4 spawn L−1 could be recommended to increase the production of catla fry in the indoor biofloc system.

“…The replacement of animal protein was not evaluated in the goldfish diet, but for a similar species ( Carassius auratus gibeo ), the inclusion of soybean meal even at lower levels (14.6%) compromised performance (Liu et al, 2016). Goldfish production in BFT systems has shown better control of water quality and improved animal growth when compared with the clear water production system (Besen et al, 2021; Faizullah et al, 2015; Wang et al, 2015). The BFT system has recently shown to increase the activity of digestive enzymes of goldfish (Yu et al, 2020), but the use of alternative feed ingredients for replacing conventional fish meal, as well as ingredients that may promote intestinal health, remains to be evaluated.…”

This study evaluated the effects of different dietary inclusion levels of fermented soybean meal (FSM) as replacement for fish meal and their effects on the productive performance and intestinal condition of goldfish (Carassius auratus) produced in biofloc (BFT) system. Five isoproteic (39.5% crude protein) and isoenergetic diets (4250 kcal kg −1 of crude energy) were formulated with FSM inclusion levels of 0%, 7%, 14%, 21% and 28% (0, 11, 22, 32 and 43 fish meal replacement). A total of 400 goldfish (0.25 ± 0.02 g) were weighed and distributed in 20 glass aquariums (15 L). Fish were fed twice daily for 56 days. The diet with FSM inclusion level of 28% reduced the weight gain and the specific growth rate and increased the feed conversion of the goldfish. Diets with FSM inclusion levels of 21% and 28% increased the α-amylase activity in the fish intestine. The diet with FSM inclusion level of 21% increased total height of the intestinal villi of the goldfish. In conclusion, the inclusion of up to 21% of FSM can replace fishmeal without affecting the growth of goldfish juveniles reared in BFT system. Fish fed 21% of FSM showed evidence of improvement in the intestinal health.
