Control of Invasive Carp Using Non-Physical Barriers Control Of Invasive Carp Using Non-Physical Barriers Kaveh Someah, General Manager-Ovivo USA,LLC [email protected] 801-931 3010 Invasive Asian Carp Invasive Carp Issues Common carp European origin: invasive species in US Voracious bottom feeders- destroy aquatic habitat Affects wildfowling Grow large quickly Prolific spawners Spread rampantly throughout interconnected watercourses Probably the most damaging Common carp, Cyprinus carpio invasive fish [Sorensen & co-workers, University of Minnesota] Control Strategies • Various strategies can be considered: fish removal, rotenone, fish isolation • Isolation methods depend on identifying critical migration corridors, key times of migration, then blocking fish movements with physical or behavioural barriers • Need to consider fish population dynamics (what number of fish passing would be critical?) [Sorensen & co-workers, University of Minnesota] Basis for Multi-Stimulus Barriers • No behavioural barrier of any type is 100% effective for relevant species and lifestages • Animal behaviour is invariably a multiplex response to a complex of different signals in the environment, so why stick to one stimulus? • Different stimuli can interact to great effect to create a synergistic response • A complex of signals is less likely to be affected by an environmental perturbation (e.g. passing barge) Available Alternatives Are • Physical Barriers • Non-Physical Barriers Advantage of Non Physical Over Physical Barriers Non Physical Barriers have the following potential benefits: • No blockage risk/ flow impedance • In some cases can be species-selective • No barrier to navigation Non-Physical Fish Deterrent Technologies • Air Bubble Curtain Barriers • Electric Barriers • High Intensity Light Barriers • Acoustic Barriers (Sound Projector Arrays –SPAs, Bio- Acoustic Fish Fence –BAFF) • Combination of above Fish Deterrent Technologies (FDT) • Large Scale FDTs has well been established for fish exclusion from power plant and other water intakes. • Full Scale FDTs in CA is used to divert down migrating chinook salmon from entering irrigation diversions. • So far, only electric barriers used for invasive species control (Chicago Canal) • This presentation discusses use of multiple technologies to improve barrier effectiveness Electric Barriers • Efficiency related to potential difference across fish (high PD, higher efficiency) • Voltage gradients high enough to stop juvenile fish may be unacceptable for human Health & Safety • Electric fields are distorted e.g. by steel-hulled barges passing over electrodes • Generally not selective for species (native fish movements will also be blocked) Smith Root Graduated Field Barrier Why Use Sound? • Asian carp are extremely sensitive to sound • Failure modes are different from electric barriers, e.g. effective with small fish, so complementary in effect • Sound barrier-field will not be disrupted by barge traffic Sound Sensitivity Classes High Sensitivity: ‘hearing specialists’: clupeids, carp family, catfish etc. Moderate sensitivity: most roundfish e.g. cod Low sensitivity: bottom fish and those without swimbladder Fish Sensitivity to Sound: ABR Measurement Auditory Brainstem Response Tests can be carried out to determine optimum signal frequencies Data can be used to design species- selective barriers ABR tests carried out for Bighead and Silver Carp at Havana Lab Audiograms: Asian carp vs. other fish Audiograms are quickly Goldfish measured using Acoustic Asian carp Brainstem Response (ABR) technique Asian carp show exceptionally high sensitivity and extended Extended high-frequency response Common AFD Frequency Signal Range for to 2 kHz Frequencies Asian carp Possible to configure species selective barriers in some cases Effect of Sound on Smaller Fish Whereas electric barrier performance is better for large fish, acoustic deflection works on fish of all sizes Swimbladder acts as a detuned receiver, (i.e. it is not resonant), so that hearing sensitivity is not a function of fish size (Hawkins, 1981) Limiting factor for small fish is normally swimming performance (ability to resist passive movement with current) The Bio-Acoustic Fish Fence(BAFF): How it Works “Sound trapped within a wall of Air Bubbles” The “BAFF” A pneumatic system that introduces sound into a bubble curtain Sound concentrated in bubble plume Produces a ‘wall of sound’, suitable for guiding rather than deflecting fish Acoustic Barriers Sound projector or BAFF Efficiency retained over a broad sizeFGS Sound Projector range of fish No human Health & Safety issues Sound field integrity is maintained during passage of shipping Barriers can allow selective passage of native species (depending on difference in hearing ability) Bio-Acoustic Fish Fence (BAFF): Sound trapped within a wall of bubbles BAFF – Basic Arrangement • Sound projectors at base of bubble curtain aligned to ‘couple’ sound • Speed of sound in plume is Air intermediate between that curtain of air and water • Sound is refracted into bubble curtain and is Sound contained, creating a “wall projector of sound” Deterrent Sound Signals Various sound signals have been developed. These are typically in the frequency range <3 kHz and are continuously changing. For resident fish populations, the signal can be changed at intervals to avoid habituation. Signal Development: Effect of Different Signal Types Pure tones Not effective Pulses Not effective Chirps Are Effective The Acoustic Field The effectiveness of a sound field depends on - background noise - sound propagation - reflectiveness - source interactions This can be evaluated by available acoustic model. This also ensures no unwanted ‘sound pollution’ PrISM Acoustic Model BAFF Principle 1: Sound Resonates Between Bed and Surface Resonance path ensures uniform vertical spread of sound, rather than inverse square law decay Allows the BAFF to maintain full-height wall of sound in deep water BAFF Principle 2: Sound is Trapped within Bubble Sheet Sound level drops by up to 60dB at 1m distance, creating a well-defined guidance line Decay of Sound Pressure from BAFF Centre 180 170 160 150 140 130 120 110 100 Sound 1uPa) (dBLevel re Pressure 90 -1 -0.5 0 0.5 1 Distance from centreline (m) “Leaky” BAFF Concept – to Stop Fish Jumping Extra sound projectors are added but not coupled to bubble curtain Protective “wall-of-sound” is maintained but a more diffuse sound gradient is created upstream and downstream of the barrier This reduces the shock of the sound stimulus and will allow fish to turn back earlier Intended to reduce risk of fish jumping barrier Adding Other Stimuli Combinations of Bubbles, Sound, High Intensity Lights and Electric Fields Basis for Multi-Stimulus Barriers No behavioural barrier of any type has been found to be 100% efficient for all species and lifestages (e.g. electric barriers less efficient for small fish) Animal behaviour is a response to a complex of different signals in the environment, so why stick to one stimulus? Different stimuli can interact to create a synergistic response A complex of signals is likely to be less affected by an environmental perturbation (e.g. passing barge) High Intensity Light Barriers Efficiency retained over a FGS Linear Low- broad size range of fish Voltage Strobe Illumination is maintained during passage of shipping Usually set to between 200 and 400 fps Adding High Intensity Light to a BAFF High Intensity Light are repellent to many fish Narrow-beam lights fitted at base of bubble plume Water more transparent in bubble sheet, allowing light to reach surface even in turbid water (In reality the lighting forms a continuous line along the barrier) MkIII SPA Systems MkIII Sound Projector Integral High Intensity Light ring Contains sound generation and monitoring electronics Designed for easy maintenance MkIII SPA Systems For GS Power Supply & Performance Monitoring Unit Total System Control Unit (microprocessor) Touch sensitive screen for operators Power Supply Units (1 per 12 Sound Projectors) MkIII SPA System Schematic Fish Diversion Concepts Developing a clear fish behavior plan : Are we blocking, or diverting or trapping and removing the fish? What path will they take? How fast will they need to swim and for how long? What are the hydraulics What other factors might intervene (e.g. flooding, disturbance of stimulus field)? Fish Diversion Concepts Invasive Species Barrier: Blockage Barrier placed across the channel to deter fish movement Opportunities for selectively deterring Stream approach velocity acoustically sensitive species (acoustic only) Success depends on strength of stimulus vs. motivational state of fish Approach velocities must not exceed Escape horizon fish swimming ability (assume 90th%ile sustainable speed) StreamlinesFish Fish Diversion Concepts Angled FDT barrier for invasive species deflection Angled barrier line produces guidance effect Fish are diverted towards one end of the barrier, reducing likelihood of Navigation lock penetration Escape horizon Streamlines Fish Fish Diversion Concepts Angled barrier for invasive species trapping Similar to angled barrier above Fish are diverted into a trap Fish trap with inscale and are Navigation lock periodically collected and Escape horizon destroyed Streamlines Fish Bypass Hemsjo Nedre, Line of Bio-Acoustic Fish Fence Angled Barrier (BAFF) Bypass & Trap ‘Pavlovian’ Conditioning Raceway trials have demonstrated that Asian carp learn to stay away from sound This indicates that sound could be used in conjunction with existing electrical barriers to

  • Clean &Unclean Meats
    Clean & Unclean Meats God expects all who desire to have a relationship with Him to live holy lives (Exodus 19:6; 1 Peter 1:15). The Bible says following God’s instructions regarding the meat we eat is one aspect of living a holy life (Leviticus 11:44-47). Modern research indicates that there are health benets to eating only the meat of animals approved by God and avoiding those He labels as unclean. Here is a summation of the clean (acceptable to eat) and unclean (not acceptable to eat) animals found in Leviticus 11 and Deuteronomy 14.

Copyright O 1995 Marine Resources Foundation Potential Consumer Acceptance of Canned Bighead Carp: A Structural Model Analysis CAROLE R. ENGLE PIERRE-JUSTIN KOUKA Aquaculture/Fisheries Center University of Arkansas at Pine Bluff 1200 N. University Drive Pine Bluff, AR 71601 Abstract The effects of socio-demographic factors on consumer ratings of product attributes of an experimental canned bighead product were analyzed. OLS techniques were used to evaluate the effects of experience consuming other canned fish products, race, gender, age, and income on the taste, tex- ture, appearance, and aroma of canned bighead. A logit analysis was then used to measure the effects of these variables on binary choice variables related to preference comparisons and willingness-to-pay as much for canned bighead as for canned salmon and canned tuna. Responses between the com- parisons of canned bighead and canned salmon or canned tuna varied. In- come, region, and gender significantly affected ratings on product attributes while taste variables significantly affected consumers' willingness-to-pay as much for canned bighead as for canned tuna. Conditional probabilities showed more clearly the effects of age, income, and gender on taste ratings, the subsequent effects of taste on preferences, and ultimately on willingness-to- pay. Probabilities estimated showed that canned bighead competes more fa- vorably with canned tuna than with canned salmon. Keywords consumer preferences, structural model analysis, logit. marketing, aquaculture Introduction Bighead carp (Hypophthalmicthys nobilis) have been raised in Arkansas in poly- culture with catfish in commercial fish ponds in an attempt to improve water quality since the 1970s.

  • A Brief Diet Analysis of Common Carp and Channel Catfish by Brent Campos
    A Brief Diet Analysis of Common Carp and Channel Catfish By Brent Campos Four mainstem nonnative fish, two channel catfish (Ictalurus punctatus) and two common carp (Cyprinus carpio), were captured using hook-and-line during our research expedition down the Grand Canyon in March, 2005. The stomachs of the fish were removed and their contents analyzed. The two species of fish appeared to exhibit divergent methods of feeding, despite having very similar organisms in their stomachs. Catfish displayed a selective, possibly mid-water picking strategy, while carp appeared to be consuming benthic substrates with their prey. Figure 1. The 405 mm common carp with its abdominal cavity cut open. Note the large ovaries, which are yellow and grainy in appearance (photo: Chris Hammersmark). One common carp was caught near sunset in a small eddy near Bass Camp at river mile 108 on March 21. It was male, measured 370 mm standard length (SL) and exhibited spawning colors. Identifiable stomach contents included aquatic Coeloptra (beetles), one oligochete, many pebbles, and detritus, among other benthic inverts. The presence of numerous pebbles indicates this fish was probing substrates for food, as would be expected for this species. The second common carp was caught near the mouth of the backwater at river mile 137, which was at the separation point of the eddy that created the site’s sandbar. The carp was female, 405 mm in length (standard length), and displayed spawning colors. Her ovaries made up approximately 50% of her abdominal cavity by volume. Gut contents were comprised of 95% algae and 5% a mix of detritus and aquatic invertebrates.

  • Fishing for and Eating Carp in Utah by Dan Potts
    Fishing for and Eating Carp in Utah by Dan Potts History and International Importance Common (Eurasian) Carp, Cyprinus carpio, is native to Europe and Asia, one of a variety of ecologically different “Eurasian” carp species including silver, bighead, and black. Largely because of their fast growth and large size and their ability to live almost anywhere in temperate and tropical areas they have been introduced virtually everywhere in world primarily as a food fish. Over the centuries that species has become the number one freshwater fish grown for human consumption, by far! They are relatively easy to grow and harvest and make great table fare if they live in unpolluted waters. Mostly due the completion of the Transcontinental Railroad they were introduced to Utah in the late 1800s as both a food and sport fish and, have proliferated here ever since. Unfortunately, almost everything our parents and friends have told most us about common carp as we have grown up here in America is untrue! Me and Carp I have a lifelong history with carp. They were the first fish I pursued as a kid, riding my bicycle all over the Salt Lake Valley to find them and other fishes. Because my grandfather had helped to start the first duck club (The Utah Duck Club) in Utah, I would bike all the way out to the Great Salt Lake marshes to fish there for 10 to 20- pound trophy carp. My knowledge about the ecology and behavior of species grew as I learned how to hook and land these huge fish.

Asian Carp Could Help Us Solve Hunger Problem Author: Michael Tran Overview Bighead carp and silver carp (Invader Species – Asian Carp) invaded the Illinois River waterway over a decade ago. Populations of these fishes have apparently grown dense in the lower and middle Illinois Rivers and both species are approaching the Chicago Area Waterway System (CAWS) and potentially making their way into Great Lakes. So far, positive DNA of Asian Carp has been found beyond the defensive electrical barrier, which means they have made their way to Great Lakes somehow. Asian Carp are fast growing, aggressive, and adaptable fish that are outcompeting native fish species for food and habitat in much of the mid-section of the United States. Asian Carp were imported into the U.S. in the 1970s to filter pond water in fish farms in Arkansas. Flooding allowed them to escape and establish reproducing populations in the wild by the early 1980s.
