Genomics breeding and multi-trait optimization will develop ocean crops competitive with land crops for production costs and nutrition benefits. This will enable profitable and sustainable kelp cultivation in nearshore coastal environments and the USA EEZ. Crop improvement will reduce the seaweed trade imbalance and provide jobs in ocean farming to fishermen who are suffering from declining catches. Our goal is to provide consumers with desirable, nutritious, healthy and inexpensive food, feed, and fuel from the sea.<\/p>\n\n\n\n<\/div>\n    \n      <\/div>\n\n\n  <\/div><\/div>\n\n\n  \n    \n\n\n\n\n\n\n<div\n  class=\"cc--component-container cc--spacer \"\n\n  \n  \n  \n  \n  \n  \n  >\n  <div class=\"c--component c--spacer\"\n    \n      >\n\n    \n\n  <\/div><\/div>\n\n\n\n\n\n  \n    \n\n\n\n\n\n\n<div\n  class=\"cc--component-container cc--full-width-image-and-text \"\n\n  \n  \n  \n  \n  \n  \n  >\n  <div class=\"c--component c--full-width-image-and-text\"\n    \n      >\n\n    \n      <div class=\"image-container\">\n          \n<div class=\"f--field f--image\">\n\n    \n    \n    \n    \n    \n    \n              \n      <img\n                            data-src=\"https:\/\/dornsife.usc.edu\/reeu-usc-altasea-blue-economy-program\/wp-content\/uploads\/sites\/110\/2023\/04\/proj_kelp2-750x432.jpg\"\n                    data-sizes=\"(min-width:1200px) 75vw, (min-width:768px) 83vw, 100vw\"          class=\"lazyload\"\n        \n                  role=\"none\"\n        \n        \n                                      \/>\n\n    \n    \n  \n  \n\n<\/div>\n    <\/div>\n  \n  <div class=\"text-container\">\n\n    \n              \n<div class=\"f--field f--section-title\">\n\n    \n  <h2>\n          Sporeless Kelp\n      <\/h2>\n\n\n<\/div>\n    \n              \n<div class=\"f--field f--description\">\n\n    \n  <p>Permitting large scale cultivation of domesticated kelps in open ocean will require precaution as far as natural kelp populations go. An approach is required that will ensure no gene flow from domesticated farmed kelps to fragile natural populations. To develop non-GMO sporeless kelp crops, we are taking advantage of the haplo-diplontic reproductive cycle of kelps, which is uniquely well suited to domestication and F<sub>1<\/sub> cultivation. The diploid sporophyte generation is the harvested crop (fronds). The haploid gametophytes can be indefinitely vegetatively propagated in culture. In these cultures, we are identifying natural mutations (knock outs) in genes required for meiosis (using sequencing and bioinformatic approaches). The crosses of male and female gametophytes with compromised function in the same meiosis gene will ensure complete sporophyte sterility.<\/p>\n\n\n\n<\/div>\n    \n      <\/div>\n\n\n  <\/div><\/div>\n\n\n  \n    \n\n\n\n\n\n\n<div\n  class=\"cc--component-container cc--spacer \"\n\n  \n  \n  \n  \n  \n  \n  >\n  <div class=\"c--component c--spacer\"\n    \n      >\n\n    \n\n  <\/div><\/div>\n\n\n\n\n\n  \n    \n\n\n\n\n\n\n<div\n  class=\"cc--component-container cc--full-width-image-and-text \"\n\n  \n  \n  \n  \n  \n  \n  >\n  <div class=\"c--component c--full-width-image-and-text\"\n    \n      >\n\n    \n      <div class=\"image-container\">\n          \n<div class=\"f--field f--image\">\n\n    \n    \n    \n    \n    \n    \n              \n      <img\n                            data-src=\"https:\/\/dornsife.usc.edu\/reeu-usc-altasea-blue-economy-program\/wp-content\/uploads\/sites\/110\/2023\/04\/proj_water-750x432.jpg\"\n                    data-sizes=\"(min-width:1200px) 75vw, (min-width:768px) 83vw, 100vw\"          class=\"lazyload\"\n        \n                  role=\"none\"\n        \n        \n                                      \/>\n\n    \n    \n  \n  \n\n<\/div>\n    <\/div>\n  \n  <div class=\"text-container\">\n\n    \n              \n<div class=\"f--field f--section-title\">\n\n    \n  <h2>\n          Seawater Intake Monitoring\n      <\/h2>\n\n\n<\/div>\n    \n              \n<div class=\"f--field f--description\">\n\n    \n  <p style=\"background: white; margin: 0in 0in 9.6pt 0in;\"><span style=\"font-size: 10.5pt; font-family: 'Georgia',serif; color: #333333;\">At present, we know little about key seawater parameters and how they might vary through time (daily\/seasonally) at the intake site.

Its native origin is in Mediterranean sea, and it is an obligate component of corresponding diet. This blue mussel has extended its range to California, where it si considered naturalized. Several farms in Southern California (Carlsbad Aquafarms, Santa Barbara Mariculture) farm it, and regulators have accepted that \u2013 while not a native species \u2013 it poses limited harm to natural populations of other mussels such as native M. californicus. One problem with this mussel, however, is that after it spawns out, it loses commercial value. Ideal mussel would ripen with the accumulation with abundant healthy lipid, but it would fail to transmit to spawning, thus remaining ripe and harvestable for extended time. Not only triploid blue mussels grow as all male sterile populations, they also remain ripe for several months, making them a higher value crop. We are working on induction of tetraploid animals to, then, consistently producing triploids by breeding tetraploid males with diploid females.
