“…Fishmeal replacement with alternative ingredients (such as soybean meal and poultry by‐products meal) has been tested previously on L. guttatus (Hernández et al., ; Silva‐Carrillo et al., ); however, the effects on gene expression have not been analysed. The present study shows that complete fishmeal substitution by a vegetable blend in L. guttatus diet results in a negative impact in growth performance and in the expression of growth‐related genes.…”

The rose spotted snapper is an important fishery resource with potential for farming in several Latin American countries. Since transcriptomic information was not available for this species, we generated a reference transcriptome from eleven tissues (brain, heart, gonad, liver, gut, muscle, white skin, dark skin, and visceral fat) using Illumina HiSeq2000 platform. Transcriptome assembly and annotation were performed with Trinity and Trinotate respectively; 267,601 contigs were assembled, average contig length was 845 bp; 85,677 putative protein sequences were identified. Sixty‐six per cent of them showed a significant match to the SwissProt Database. From this assembly, we selected growth/atrophy‐related genes to investigate the effect of dietary protein source on gene expression. Pacap expression was measured in the brain; igf1, igf2 and ghr were measured in liver; and mtor, igf1, igf2, myod1, myod2, myogenin, foxo3a, foxo3b, murf1, mafbx, mstn1 and mstn2 were measured in muscle. A feeding trial with juveniles was performed, in which three diets were formulated, a fishmeal‐based diet (FM), a terrestrial animal protein diet (PPM) with porcine meat meal and poultry by‐products meal, and a vegetable diet (VEG) with a blend of soybean protein concentrate and corn gluten. A reduced expression of somatotropic and myogenic genes in fish fed the VEG diet was observed; however, expression of atrophy genes did not increase with this diet suggesting that atrophy mechanisms were not involved. These results indicate that protein from a vegetable source does not provide proper amino acid requirements to juvenile fish, decreasing expression of myogenic and other growth‐related genes.

“…PBM is generally regarded as the most effective of PAPs from a nutritional standpoint (Davies et al., ). PBM protein can replace the dietary FM protein without adverse effects on growth up to 25% for tench ( Tinca tinca , González‐Rodríguez et al., ) and black sea turbot ( Psetta maeoticus , Yigit et al., ), up to 30.7% for cobia ( Rachycentron canadum , Zhou et al., ), up to 67% for totoaba ( Totoaba macdonaldi , Zapata, Lazo, Herzka, & Viana, ) and Florida pompano ( Trachinotus carolinus , Rossi & Davies, ), up to 75% for rainbow trout ( Oncorhynchus mykiss , Parés‐Sierra et al., ) and spotted rose snapper ( Lutjanus guttatus , Hernández et al., ) and up to 100% for humpback grouper ( Cromileptes altivelis , Shapawi, Ng, & Mustafa, ), Nile tilapia ( Oreochromis niloticus , El‐Sayed, ; Hernández et al., ) and hybrid striped bass ( Morone chrysops × Morone saxatilis , Rawles et al., ). Apart from using PBM as sole dietary PAP protein replacer, this feedstuff has also been used successfully in blends with other nonruminant PAPs (Hatlen et al., ; Liland et al., ).…”

“…PBM protein is known to contain lower levels of lysine and methionine, as well as of most other essential amino acids, compared to FM (González‐Rodríguez et al., ; Hernández et al., ; Zapata et al., ). These amino acid shortages in PBM could suppress fish growth when replacing FM at high levels (González‐Rodríguez et al., ; Yigit et al., ), although this has not been observed in many cases (Hernández et al., , ; Zhou et al., ). Such variable findings among the various studies could be attributed to whether the tested PBM‐based diets have met the essential amino acid requirements of the targeted species.…”

Effect of fishmeal replacement by poultry by-product meal on growth performance, proximate composition, digestive enzyme activity, haematological parameters and gene expression of gilthead seabream (Sparus aurata )

In order for aquaculture to satisfy the increasing demand for farmed fish, it is essential that the sector continues searching for suitable alternatives to fishmeal (FM) that are both cost-effective and widely available. Over the last decades, plant proteins have been used successfully to reduce the inclusion levels of FM in the diets of most farmed fish species, but the high inclusion levels reduce feed intake, fish growth and nutrient bioavailability in fish body, having also negative impacts on the aquatic environment (Bell & Waagbø, 2008;Hardy, 2010). Further, the prices of many plant proteins have increased dramatically over the last decades because of the increasing demand for their use in feeds, human foods and ethanol production (Hardy, 2010). Of most importance, however, is the fact that as the aquafeed sector is expanding to satisfy the increasing demand of intensive aquaculture for aquafeeds, greater amounts of FM are required; thus, the exploration for suitable and cost-effective protein alternatives is ongoing. AbstractTwo feeding trials examined the replacement of fishmeal (FM) with poultry byproduct meal (PBM) in the diet of juvenile Sparus aurata. In Feeding trial I (100 days), three diets were formulated, where FM protein was replaced by 50% (PBM50) and 100% (PBM100) PBM, while in Feeding trial II (110 days), four diets were formulated using the same FM control diet, but FM was replaced at lower levels: 25% (PBM25), and 25% (PBM25 + ) and 50% (PBM50 + ) with the supplementation of lysine and methionine amino acids. PBM protein can successfully replace 50% of FM protein in the diet of S. aurata without adverse effects on survival, feed intake, growth performance and feed utilization, given that the diet is balanced with lysine and methionine.The proximate composition of body and muscle was unaffected by the diet, but the total FM replacement resulted in reduced lipid and energy contents in fish. A fifty per cent FM replacement by PBM did not affect haematological parameters indicating a good fish health. Similarities in trypsin and chymotrypsin activities with FM-fed fish suggest a high digestibility of PBM. High dietary levels of PBM reduced the liver gene expression of GH/IGF axis and of cathepsin D suppressing fish growth and modulating the protein turnover.
