A system and method of sustainable aquaponics that vertically integrates unique aquaponic system designs with alternative aquaculture fish feed sources, fingerling production methods, alternative aquaculture / farmed fish grow out models, and green energy sources that yield organic produce in the form of fruits and vegetables. A raceway system serves for grow-out throughout the warm and cold months. During the summer months, fish can be spawned and fed for steady growth, while during the winter months, the fish continue to grow at slower quite acceptable growth rates. The present invention derives its water from an open, natural, established pond or lake ecosystem to ensure that the raceways are adequately seeded with all of nature's good and bad bacteria and algae. The present invention can include winter quarters for the fish that is well-insulated and heated to ensure that the fish are comfortable and will continue growing and spawning throughout winter months.

Quantification of vitellogenin
InactiveUS20090011447A1Simple methodMicrobiological testing/measurementPeptidesVitellogeninsGlu-Val-Gly
The present invention is directed to a simple method for absolute quantification of plasma vitellogenin from two or more different fish species such as Rainbow trout and Atlantic salmon, or Atlantic cod and haddock. In the case of Rainbow trout and Atlantic salmon, plasma samples obtained from control and β-estradiol induced fish were digested with trypsin. A characteristic ‘signature peptide’ was selected and analyzed by high performance liquid chromatography coupled to an electrospray quadrupole-time-of-flight tandem mass spectrometer, using a deuterated homologue peptide as an internal standard. The hybrid tandem mass spectrometer was operated in a ‘pseudo’ selected reaction monitoring mode by which three diagnostic product ions were monitored for identification and quantification purposes. The reproducibility (coefficient of variation ˜5%) and sensitivity (limit of quantification of 0.009 mg / mL) achieved by this simple assay allow it to be considered as an alternative to immunological assays. In the case of Atlantic cod and haddock, the amino acid sequence of the vitellogenin protein has not yet been determined, but, the Atlantic cod vitellogenin has been characterized using a ‘bottom-up’ mass spectrometric approach. Vitellogenin synthesis was induced ‘in vivo’ with β-Estradiol, and subjected to trypsin digestion for characterization by matrix-assisted laser desorption / ionization-Quadrupole-Time-of-flight tandem mass spectrometry. A peptide mass fingerprint was obtained and ‘de novo’ sequencing of the most abundant tryptic peptides was performed by low energy collision induced dissociation-tandem mass spectrometry. Thus, the sequences of various tryptic peptides have been elucidated. It has also been determined that Atlantic cod vitellogenin shares a series of common peptides with the two different known vitellogenin sequences of Haddock, a closely related species. There are also disclosed novel isolated signature peptides, namely Thr-Tyr-Phe-Ala-Gly-Ala-Ala-Ala-Asp-Val-Leu-Glu-Val-Gly-Val-Arg, Asp Leu Gly Leu Ala Tyr Thr Glu Lys, Phe Phe Gly Gln Glu Ile Ala Asn Ile Asp Lys, Glu Ile Val Leu Leu Gly Tyr Gly Thr Met Ile Ser Lys and Tyr Glu Ser Phe Ala Val Ala Arg.
