“…Both biofloc and periphyton presented nutritious food sources for the cultured animal (Bossier and Ekasari, 2017;Wasielesky et al, 2006). While the biofloc protein content in our research was comparable to those in previous research (Khanjani et al, 2016;Kumar et al, 2018;Pan, 2012, 2014), the periphyton protein content was almost double that of biofloc and the reported figure for periphyton (25% of dry matter) in substrate-added Pacific white shrimp culture (Kumar et al, 2017). It is possible that part of the residual feed was trapped in the rim of periphyton at the water-air interphase, resulting in high periphyton protein content.…”

Effects of carbohydrate addition frequencies on biofloc culture of Pacific white shrimp (Litopenaeus vannamei)

et al. 2021

In Pacific white shrimp culture, adding organic carbohydrate to the pond besides feed improves water quality and shrimp performance. While the feeding frequency has significant effects on shrimp production, how often carbohydrate should be added remains unknown. This research investigated the effects of carbohydrate addition frequency of 1, 3, and 6 times per day on Pacific white shrimp production. Tapioca powder was used as carbohydrate source to maintain an input C:N ratio of 12. The same daily ration of tapioca was applied, but divided into equal portions according to the application frequency. The shrimp performance was better in carbohydrateadded systems than in a conventional system without additional carbohydrate, but the carbon retention efficiency was lower. Splitting daily dosage of carbohydrate into more frequent additions had no significant effect on Pacific white shrimp performance, and carbon and nitrogen retentions. A carbohydrate addition frequency of once per day is recommended for good performance of Pacific white shrimp in biofloc rearing systems.

“…The Pacific white shrimp, Litopenaeus vannamei , is characterized by rapid growth and high adaptability and is one of the highest yielding species used globally for shrimp farming (Yuan et al, 2019). In recent years, the irrational intensive culture methods of over‐stocking and excessive use of proteinaceous feeds have been destroying the aquafarming system, severely weakening shrimp immunity and leading to repeated disease outbreaks (Santhana Kumar et al, 2018). Microbial diseases have caused substantial economic losses and become a major threat to shrimp aquaculture.…”

Growth performance, non‐specific immunity and Vibrio parahaemolyticus resistance of Pacific white shrimp, Litopenaeus vannamei , in response to various microbial‐derived additives

et al. 2020

A study was conducted to evaluate the effects of various microbial‐derived additives on the growth performance, non‐specific immunity and disease resistance of Litopenaeus vannamei. Shrimp were fed diets supplemented with 5 g/kg multi‐species probiotic (MSP), 5 g/kg dried lactic acid bacteria fermentate (LF), 5 g/kg dried yeast fermentate (YF), 7.5 g/kg cell wall‐broken yeast extract (BY), 5 g/kg multi‐enzyme preparation (MEP), or 50 g/kg complex probiotics and enzyme (CPE). Results showed that the specific growth rate of shrimp in all treatment groups, except the LF group, was significantly enhanced (p < .05). The activities of lipase and trypsin in the hepatopancreas of the MSP and MEP groups, and amylase of the BY group, increased significantly (p < .05). The activities of all non‐specific immune enzymes in serum in MSP, BY group and the activity of haemocytes respiratory burst in the MSP, YF, BY and MEP group were significantly increased (p < .05). In the Vibrio challenge test, the cumulative mortality of shrimp in all treatment groups, except MSP group, was significantly lower than in the controls (p < .05). In conclusion, various microbial‐derived additives provided distinct benefits to the growth performance and health of shrimp. Particularly, complex probiotics and enzyme exhibited the all‐round positive influence and significantly improved growth performance, immunity capacity and disease resistance.

“…Besides a nutritionally balanced diet, the water environment is also a very important factor. Currently, there is growing interest in the application of biofloc technology in aquaculture systems to support sustainable development goals (Bossier & Ekasari, 2017;Kumar et al, 2018). Biofloc is a conglomeric aggregation of microbial communities, such as phytoplankton, bacteria, and living and dead particulate organic matter.…”

“…In heterotrophic dominated biofloc technology, additional carbon is added into the aquaculture system to shift the carbon/ nitrogen ratio (C/N ratio), and thereby enhance the bio-conversion of toxic nitrogenous waste into useful microbial protein (Avnimelech, 1999;Crab, Avnimelech, Defoirdt, Bossier, & Verstraete, 2007;Hargreaves, 2006). Biofloc technology has been successfully applied to the farming of shrimp and prawn (Emerenciano, Gaxiola, & Cuzon, 2013;Kumar et al, 2018). It has been reported that intermediate levels of biofloc create factors propitious for maintaining the productivity and stability of super-intensive Litopenaeus vannamei aquaculture system (Schveitzer et al, 2013).…”

Spent brewer's yeast as a replacement for fishmeal in diets for giant freshwater prawn (Macrobrachium rosenbergii), reared in either clear water or a biofloc environment

A 90‐day feeding experiment was conducted in order to test spent brewer's yeast as a replacement for fishmeal in diets for giant freshwater prawn (Macrobrachium rosenbergii) reared in either a recirculating aquaculture system (RAS) or a biofloc system. Triplicate groups, each of 20 prawn (6.7 ± 0.03 g), were randomly assigned to 24 identical tanks. Twelve tanks were connected to the RAS, and the other 12 tanks were connected to the biofloc system which were initially supplemented with Bacillus subtilis, molasses and blood meal to achieve a C:N ratio of 20:1. Four iso‐nitrogenous (350 g/kg) and iso‐energetic (19 MJ/kg) diets where 0%, 20%, 40% and 60% of fishmeal protein was replaced by spent brewer's yeast. Neither growth nor survival was affected (p > 0.05) by increasing levels of brewer's yeast. The exception, being fish given 60% replacement with brewer's yeast, reared in biofloc, which displayed a higher (p < 0.05) growth than fish given 40% replacement, reared in clear water. The feed conversion ratio of prawn reared in the biofloc environment was lower than in the clear water. We concluded that spent brewer's yeast represents a possible 60% substitute for fishmeal in giant freshwater prawn diets, especially for prawn reared in a biofloc environment.
