Replacement of fishmeal by fish protein hydrolysate and biofloc in the diets ofLitopenaeus vannameipostlarvae

Abstract

This study aimed to evaluate the effect of the gradual replacement of fishmeal with fish protein hydrolysate (FPH) and biofloc flour (BF) in the diets of white shrimp Litopenaeus vannamei postlarvae (2 mg). Five diets (420 g kg À1 of crude protein) were formulated, and these replaced 0 (control), 10, 20, 30 and 40% (T0, T10, T20, T30 and T40, respectively) of the fishmeal. A commercial diet was used as an external control. The alternative ingredients FPH and BF were added at a ratio of 1 : 1. After 42 days, the shrimp survival was higher than 99% in all the treatment groups. A regression test indicated that the ideal fishmeal substitution level to obtain optimal zootechnical parameters (final weight, weight gain and protein efficiency) is between 15.16 and 16.5%. In this study, we demonstrated that BF and FPH are potential ingredients that can be used to replace fishmeal in L. vannamei postlarvae diets.

Nursery performance of Pacific white shrimp (Litopenaeus vannamei Boone, 1931) cultivated in a biofloc system: the effect of adding different carbon sources

“…Biofloc system provides an available rich natural resource of protein‐lipid at any time (Avnimelech ) with highly diverse components (Martinez‐Cordova et al . ) consisting bacterial protein (Ballester, Abreu, Cavalli, Emerenciano, Abreu & Wasielesky ; Hargreaves ), poly‐β‐hydroxybutyrate created by bacteria (De Schryver, Sinha, Kunwar, Baruah & Verstraete ), microalgae, protozoa, nematodes (Azim, Little & Bron ; Valle, Jr, Silva, Bezerra, Correia, Peixoto & Soares ), copepods and rotifers (Ray, Lewis, Browdy & Leffler ) and diatoms, copepods and polychaetes (Porchas‐Cornejo, Martinez‐Cordova, Martinez‐Porchas, Barraza‐Guardado & Ramos‐Trujillo ). These natural products play an important role in recycling nutrients, improvement of growth performance and activity of digestive enzymes in shrimp (Xu & Pan ; Xu, Pan, Zhao & Huang ; Xu, Pan, Sun & Huang ).…”

Evaluation of dietary soybean meal as fish meal replacer for juvenile whiteleg shrimp, Litopenaeus vannamei reared in biofloc system

“…According to our results, the higher growth performance of shrimp that were cultured in biofloc in comparison to the clear water group is in agreement with previous findings (Ray et al 2011;Irshad et al 2016). Valle et al (2015), replaced fish meal with biofloc flour and protein hydrolysate in the diet of L. vannamei and indicated that biofloc flour is a potential ingredient that can be used as substitute for fishmeal. In our study, whole-body proximate composition was not affected much by the FM substitution with SBM.…”

Influence of replacing fish meal with enzymatic hydrolysates of defatted silkworm pupa (Bombyx moriL.) on growth performance, body composition and non-specific immunity of juvenile mirror carp (Cyprinus carpio var. specularis)

“…It is an ideal technology for converting low value by products into biologically functional products (Gildberg, ; Shahidi & Botta, ). Numerous studies found that plants and animals protein hydrolysates have been widely investigated in aquaculture (Aksnes, Hope, & Albrektsen, ; Aksnes, Hope, Hostmark, & Albrektsen, ; Cordovamurueta & Garciacarreno, ; Song et al., ; Valle et al., ). However, there is little information concerning enzymatic hydrolysate of defatted silkworm pupa (EHDSP) applied in aquatic animal culture.…”
