Fish
Cultivated seafood — salmon, trout, and other teleosts — is an active cell-ag category pursued by companies including Wildtype, BlueNalu, and Umami Bioworks. This page collects the fixed data artifacts relevant to cultivated finfish: the Atlantic salmon genome-scale metabolic model, the AQUA-FAANG functional-annotation resource, and individual transcriptomic / proteomic deposits spanning muscle growth, myogenesis regulation, adipocyte differentiation, and storage/spoilage. “Fish” here spans the salmonids and other aquaculture teleosts surveyed for cultivated-meat work; it is a broad page covering many species rather than a single binomial.
Featured atlases
AQUA-FAANG
The FAANG consortium’s aquaculture programme — Advancing European Aquaculture by Genome Functional Annotation — generating genome-wide functional annotation maps for six aquaculture species important to European aquaculture (Atlantic salmon, rainbow trout, European sea bass, gilthead sea bream, common carp, turbot); the data hub hosts its open releases. A FAANG functional-annotation substrate for cell-ag-relevant aquaculture-cell-line work. Full entry in Databases.md / Livestock Multi-Tissue Atlases.
Genome-scale metabolic models
GEMs are SBML-formatted reconstructions of an organism’s metabolic network — every reaction, every metabolite, every gene-protein-reaction mapping — and are the input data structure for the constraint-based modeling tools listed in Software.md / Metabolic Modeling & Strain Design. The salmon reconstruction below inherits network structure from the human reference GEMs catalogued in HumanReference.md.
SALARECON — Salmo salar (Atlantic salmon)
Whole-genome metabolic reconstruction of Atlantic salmon, published 2022 in PLOS Computational Biology, built to connect genome content to growth and feed-efficiency phenotypes for aquaculture. It is the most directly applicable existing GEM for cultivated salmonid modelling — though not purpose-built for cultivated meat — and relevant to the cultivated seafood category (salmon, trout) attracting investment from companies such as Umami Bioworks, BlueNalu, and Wildtype. SBML files distributed via the paper’s supplementary materials and the SALARECON repository at gitlab.com/digisal/salarecon.

Muscle growth & myogenesis
The bulk of the fish data surveyed here is skeletal-muscle transcriptomics across a wide taxonomic spread — the substrate for understanding how finfish muscle grows, the trait a cultivated-seafood process is built around. Studies span exercise-induced muscle remodelling in rainbow trout (SRA051669.1), myogenic regulatory genes in beltfish (SRX1674471), growth-hormone-transgenic coho salmon (PRJEB7712), spawning-associated muscle wasting in Atlantic cod (SRR955389–SRR955396), compensatory growth in fine flounder (SRS643409), age-series muscle transcriptomes in Schizothorax prenanti (SRP074282), microRNA–SmyD1 regulation in Chinese perch (GSE97173), fast- vs slow-growing phoenix barb (PRJNA848289), exercise-driven muscle-texture improvement in a hybrid cyprinid (PRJNA843454), pigmentation-linked muscular atrophy in Atlantic salmon (PRJNA706530), and a multi-population skeletal-muscle epigenomic study of large yellow croaker (Xie et al. 2024, Frontiers in Molecular Biosciences, PRJNA1124228) — the closest existing cultivated-yellow-croaker substrate.
Myoblast cell lines & myogenic differentiation
The most directly cultivated-meat-relevant fish datasets are the in-vitro ones. The establishment of a continuous myoblast cell line in the marine teleost Sebastes schlegelii (PRJNA661185, also CNGB CNP0000222) — propagated 50 passages over 150 days — and a proteomic characterisation of primary cultured gilthead sea bream myocytes across myogenic-differentiation stages together provide a close fish analogue to the bovine and porcine satellite-cell work that anchors cultivated-meat cell biology. A more recent label-free LC-MS/MS proteomic comparison of early (P3) vs late (P20) passages of an SBM Lates calcarifer muscle cell line (Pawaskar et al. 2026, Current Proteomics) profiles 454 proteins relevant to myogenic progression in barramundi — the dominant Indo-Pacific aquaculture finfish and an active cultivated-seafood target.
Adipocyte differentiation
Two microarray time-series profile finfish adipocyte biology — proliferation and differentiation of rainbow trout adipocyte precursor cells (GSE90058) and differentiation of the Atlantic salmon adipose-derived stromo-vascular fraction into adipocytes (GSE18389) — relevant to engineering the fat component of cultivated seafood.
Atlases, proteomes & quality profiling
A final cluster covers reference-scale and quality-oriented resources: a single-cell transcriptome atlas of zebrafish development (PRJNA564810), a spatial transcriptomic atlas of Atlantic salmon skin (PRJNA970983), the PeptideAtlas of the widely cultivated Labeo rohita (PRIDE PXD026377), a mass-spectrometry study of how fish-muscle metabolite profiles shift with sampling method, storage temperature, and time — directly relevant to cultivated-seafood quality and shelf-life — and a full-length-transcriptome / scRNA-seq atlas of Epinephelus coioides spleen (Huang et al. 2021, Frontiers in Immunology, SRP321375) which doubles as a methods reference for scRNA-seq pipeline development on aquaculture species without a reference genome.
