Major Aquaculture Projects and Cooperative Research
PAS provides information on the feasibility, design and construction of new production sites as well as the evaluation of existing sites. These production sites rely on PAS to market their products and to guide further expansion plans. PAS is also working with fish producers and researchers in China, Taiwan and other countries to introduce new species such as striped bass. PAS contracts with existing farms covering all aspects of the business including breeding, spawning, rearing, marketing, processing and distribution of fish.
Technical, Marketing, Financial, and Political Expertise
As part of our site evaluations, we provide technical, marketing, and financial skills, as well as a thorough knowledge of political issues to overcome restrictions to aquaculture promulgated by permit requirements and regulations, to the process.

Spawning of Striped Bass: 1. Adult Collection
Adult striped bass are collected during the spawning season (April-June) on the Sacramento River between Knights Landing and Colusa using an electro-fishing boat with support from California Department of Fish and Game. Adult females are catheterized & evaluated onboard for egg status and adult males for sperm production prior to transport.

Fish Production in Rice fields
ProAqua. designed, supervised the construction and planted three species of fish in a pilot project investigating the use of fallow rice fields for production of fish. Capturing natural occurring nutrients and protein to be transferred into fish growth.

Spawning of Striped Bass: 2. Broodstock Husbandry
River collected striped bass are transported to the UC Davis Putah Creek fish facility and transferred into 12? diameter tanks. Both domestic and rivercollected females are injected with 150 IU/kg Human Chorionic Gonadotropin (Hcg) to induce spawning. Males are injected with 75 IU/kg Hcg to increase sperm production . Fish are maintained in holding facilities at 19-20 ?C until eggs ripen which occurs 24-48 hours post-injection. In parallel, domestic broodstock (F-3 generation) & river collected fish are maintained, spawned & reared under identical conditions. Progeny from the domestic broodstock are used as controls in developmental, feeding and toxicological studies.

Spawning of Striped Bass: 3. Egg Maturation
Females are catheterized and an aliquot of eggs is removed several times over a 12-36 hours period (frequency depends on egg stage and speed of maturation) to determine the proper stage of development, such that spawning can be performed successfully.

Oregon Sturgeon Project
  • Collected wild white sturgeon from the Columbia River for propagation and rearing of wild sturgeon fingerlings.
  • Constructed a sturgeon hatchery for the production of fingerling white sturgeon for the Bonneville Power mitigation project.

Spawning of Striped Bass: 4. Artificial Fertilization
When the eggs are mature and ovulation occurs (indicated by both egg stage and eggs flowing freely from the female), females are euthanized using an overdose of MS-222. The female?s abdomen is dried with a clean towel and squeezed gently to expel free flowing eggs directly in a stainless steel bowl; subsequently the female?s abdomen is opened and ovaries are removed to collect remaining eggs. Males? (3-5 males/female) abdomens are dried to prevent sperm activation and squeezed gently to inject sperm directly into the bowl containing eggs. Water is gently added to initiate fertilization. Fertilization is completed within one minute after the addition of water.

Spawning of Striped Bass: 5. Embryo Development and Hatching
Fertilized eggs are placed into upwelling hatching jars with constant freshwater flow for incubation. Unfertilized eggs develop a positive buoyancy and are expelled out of jar through upwelling flow. Fertilized eggs develop into embryos. Development is documented at 12 hr intervals post-fertilization & egg volume/jar is measured at 24 hr to determine total egg/larval production. Hatching occurs in approximately 48hrs. The larvae are expelled from the top of the hatching jars directly into 2700 L round flow-through tanks.

Spawning of Striped Bass: 6. Larval Development and Rearing
A flow rate of ~10 L/minute is maintained in order to keep the larvae suspended within the tank throughout the developmental period. An air curtain is placed around the center standpipe of the tank preventing impingement of larvae on the drain screens and to break surface tension. Oil pads are placed on the waters surface to avoid the formation of an oil layer and to allow larvae to access air for swim bladder inflation. Hatchery lighting is adjusted to similar light levels larvae encounter in the estuary by using very dim ambient incandescent lighting. Larvae are fed newly hatched Artemia nauplii dispensed by a constant flow automatic feeder at day 5 post-hatch when exogenous feeding begins. Tanks are monitored and maintained at least twice daily. Larvae are sampled for developmental, histological, biochemical and molecular assays at 1-3, 5 & 7 days post-hatching.

Spawning of Striped Bass: 7. Transfer into Ponds
After exogenous feeding begins (5 days post-hatching), larvae are transferred to ponds (in collaboration with commercial fish farms) where they can feed on natural zooplankton supplemented with commercial fish food.

Spawning of Striped Bass: 8. Fingerling Rearing
After 6-8 weeks the ponds are seined and juvenile striped bass are transported back to the UCD-CABA Putah Creek fish facility. Juvenile striped bass are reared in 4? diameter tanks and fed a diet of commercial fish food (Silvercup salmon floating pellets).
