Yuav ua li cas los xyuas kom meej lub teeb pom kev zoo nyob rau hauv lub pas dej loj aquaculture los yog dej aquaculture tanks? Yuav ua li cas txheeb xyuas thiab daws qhov chaw tuag hauv qhov teeb pom kev zoo?

Ib, Qhov tseem ceeb ntawm kev tswj teeb pom kev zoo sib xws
1. Optimizing cov duab ntawm lub teeb pom kev zoo
Qhov kev ncua deb ntawm lub teeb pom kev zoo thiab lub cev dej yuav tsum ua raws li txoj cai "kev ncua deb mus rau qhov siab piv". Piv txwv li, yog tias koj muaj 10-meter-qhov tob aquaculture pas dej thiab siv 200W LED underwater teeb nrog lub kaum sab xis ntawm 120 degree, koj yuav tsum khaws qhov kev ncua deb ntawm lub teeb ntawm 3 thiab 5 meters kom paub tseeb tias qhov sib tshooj ntawm cov teeb pom kev nyob sib ze yog tsawg kawg yog 30%. Lub Hoobkas ua liaj ua teb hauv Qingdao siv 3D qauv software los qhia tias lub teeb yuav kis tau li cas. Cov kws tshawb nrhiav pom tias thaum lub teeb tau teeb tsa hauv qhov "plum blossom pawg" tsim, qhov sib xws ntawm lub teeb hauv qab tuaj yeem txhim kho mus rau ntau dua 85%, uas yog 22% siab dua li cov qauv matrix.
2. Kev them nyiaj rau lub teeb attenuation thiab dynamic tswj
Qhov sib txawv wavelengths ntawm lub teeb yog absorbed sib txawv los ntawm dej lub cev. Piv txwv li, lub teeb liab yog absorbed 0.3 / m hauv dej tshiab, thaum lub teeb xiav yog absorbed 0.1 / m. Yuav kom ua tau li no, multispectral LEDs yuav tsum tau siv. Hainan Lingshui sib sib zog nqus- hiav txwv aquaculture platform muaj qhov ntse dimming system uas hloov pauv lub zog piv ntawm lub teeb liab (660nm) thiab lub teeb xiav (450nm) raws li qhov tiag-cov ntaub ntawv sijhawm ntawm dej turbidity (NTU tus nqi), chlorophyll concentration (μ g / L), thiab qhov tob. Piv txwv li, thaum lub turbidity mus dhau 15NTU, lub kaw lus boosts lub teeb liab tso zis hwj chim los ntawm 40% los ua rau tawg tawg thiab ua kom tus nqi PUR nyob rau hauv cov dej sib sib zog nqus nyob rau hauv ntau yam uas kab mob xav tau.
3. Ua hauj lwm ua ke los tsim kev xav txog ciam teb
Tus nqi ntawm lub teeb uas siv yog cuam tshuam ncaj qha los ntawm qhov cuam tshuam ntawm phab ntsa sab hauv ntawm lub pas dej aquaculture yog li cas. Raws li kev tshawb fawb los ntawm Shanghai Ocean University, cov pas dej da dej nrog dawb siab - ntom polyethylene (HDPE) sab tuaj yeem cuam tshuam txog li 85% ntawm lub teeb, uas yog 60% ntau dua li cov pas dej ua vaj tse. Lawv tuaj yeem ua rau lub teeb hauv qab 1.8 npaug ntawm qhov ci dua. Tsis tas li ntawd, muab daim iav stainless hlau daim hlau (nrog rau qhov pom ntawm 92%) nyob rau hauv qab ntawm lub pas dej ua ke tuaj yeem tshem tawm cov qhov muag tsis pom ntau dua. Tom qab siv txoj hauv kev no, qhov sib xws ntawm lub teeb hauv qab hauv lub hauv paus yug me nyuam hauv Sanya tau nce los ntawm 62% mus rau 91%, thiab cov ntses cov neeg noj zaub mov tau zoo heev.
2, Txoj hauv kev nrhiav thiab suav cov chaw tuag thaum muaj teeb pom kev zoo
1. Technology rau qauv 3D teeb pom kev zoo
Siv software xws li LumenRT lossis Dialux los ua tus qauv ntxaib digital ntawm lub pas dej da dej, koj tuaj yeem pom thaj chaw tuag ntawm lub teeb los ntawm kev nkag mus rau lub teeb tsis muaj teeb meem (luminous flux, beam angle, installation qhov siab), cov dej kho qhov muag (absorption coefficient, scattering coefficient), thiab cov khoom siv roj ntsha xav tau (piv txwv li, qhov zoo tshaj plaws PAR 2000 {0} μmol / m² / s). Siv cov txheej txheem no, ua liaj ua teb cw hauv Zhanjiang, xeev Guangdong pom tias muaj thaj chaw qis qis nrog txoj kab uas hla ntawm 2 meters (PAR<30 μ mol/m ²/s) in the middle of the pool bottom under the old arrangement. The dead zone area was cut down to a diameter range of 0.5 meters after changing the space between the lights.
2. Portable spectrometer rau kev kuaj hauv daim teb
Siv lub ntsuas ntsuas qhov ntsuas tes zoo li Ocean Optics USB2000+ los ua daim phiaj ua piv txwv ntawm lub pas dej hauv dej (nrog qhov sib nrug ntawm 0.5 mus rau 1 meter) thiab sau cov qib PAR thiab spectral faib ntawm txhua qhov chaw. Nws muaj peev xwm tsim tau tus qauv sib txuas ntawm lub teeb siv thiab kev faib khoom lom neeg los ntawm kev saib cov cwj pwm lom neeg xws li ntses aggregation thiab algal adhesion. Hauv kev sib sib zog nqus-dej net tawb aquaculture sim, nws tau pom tias thaum PAR<40 μ mol/m²/s, the aggregation density of young golden carp diminished by 70%, concurrently, the proportion of detrimental dinoflagellates, such as Tremella, escalated twofold.
3. Kev kuaj mob nrog kev pab los ntawm biomarkers
Los ntawm kev saib cov cim qhia txog lub cev ntawm cov tsiaj hauv dej, suav nrog cov chlorophyll fluorescence metrics Fv / Fm thiab cov qib cortisol hauv cov ntshav ntses, peb tuaj yeem tau txais lub tswv yim ntawm qhov teeb pom kev zoo li cas. Piv txwv li, pob zeb corals ib txwm tsis tau txais lub teeb txaus thaum lawv qhov Zooxanthellae ntom tsawg dua 1 × 10 ⁶ hlwb / cm ². Tsis tas li, yog tias cov ntshav cortisol concentration hauv cov ntses ntau dua 20ng / mL, nws tuaj yeem ua rau muaj kev ntxhov siab vim yog qhov chaw tuag ntawm lub teeb raug.
3, Ib txoj kev npaj ua tiav rau kev tswj lub teeb pom kev tuag
1. Tsim cov txheej txheem teeb pom kev zoo
For deepwater aquaculture tanks, the illumination is arranged in layers, with "surface strong light+middle supplementary light+bottom weak light." In a 20-meter-deep aquaculture cabin, for instance, a 500W LED spotlight (PAR>300 μ mol / m ² / s) muab tso rau saum npoo (0-5 meters), 200W LED dej nyab teeb (PAR=100-200 μ mol / m ² / s) muab tso rau hauv nruab nrab txheej (5-15 meters), thiab 50W liab puv lub teeb (660nm, PAR{7}} μ 5 / m²) yog muab tso rau hauv qab txheej (1 m²) Txoj kev npaj no tuaj yeem tau txais cov teeb pom kev zoo kom ntau dua 80% tsis sib xws hauv txhua txheej txheej.
2. Ua hauj lwm ua ke los tswj cov dej ntws thiab lub teeb teb
Los ntawm kev sib koom ua ke ntawm cov dej ntws, koj tuaj yeem tshem tawm cov chaw tuag uas tshwm sim los ntawm kev raug lub teeb. Lub thruster hauv qab tsim cov dej ntws ntws (ntev tus nqi ntawm 0.2-0.5 m / s) nyob rau hauv lub voj voog aquaculture lub pas dej kom sib npaug sib npaug ntawm cov khoom raug tshem tawm thiab txo qhov cuam tshuam ntawm cov shading hauv zos. Qhov kev sim ua los ntawm Dalian Ocean University qhia tau hais tias qhov kev ntsuas no tuaj yeem txo qhov kev hloov pauv ntawm lub teeb hauv qab ntawm ± 60% mus rau ± 20%, ua ke txhim kho qhov sib xws ntawm cov pa oxygen los ntawm 15%.
3. Txuas ntse shading thiab ntxiv teeb pom kev zoo
Lub kaw lus ntawm cov curtains adjustable blackout thiab LED sau lub teeb yog siv los koom ua ke sab nraum zoov qhov tob tob tawb. Thaum tshav ntuj muaj zog tshaj 1000W/m², lub hnub ci yuav cia li qhib mus txog 50% transmittance kom lub teeb tsis muaj zog heev. Thaum lub hnub ci tsis muaj zog tshaj 200W / m² lossis dej tob tshaj 10 meters, LED puv lub teeb yuav pib ua kom tau raws li qhov xav tau teeb pom kev zoo. Tom qab cov txheej txheem tau muab tso rau hauv qhov tob thiab sab ntug dej hiav txwv aquaculture platform hauv Lianjiang, Fujian, lub voj voog loj hlob ntawm Pseudosciaena crocea raug txiav los ntawm 15% thiab pub coefficient raug txiav los ntawm 0.2.
4. Kev txhawb nqa los ntawm kev lag luam cov ntaub ntawv tshawb fawb thiab cov ntaub ntawv
Ua liaj ua teb rau Norwegian Salmon: Los ntawm kev muab cov txheej txheem kho qhov muag fiber ntau rau hauv qab ntawm lub tawb, lub hnub ci tuaj yeem ncav cuag thaj tsam dej tob. Thaum ua ke nrog LED sau lub teeb, PAR tus nqi ntawm qhov tob ntawm 15 meters nyob ntawm 80 thiab 120 μ mol / m ² / s. Qhov no ua rau kev loj hlob ntawm salmon los ntawm 20% thiab txo qis deformity rau tsawg dua 3%.
Cwj Pwm Loj Loj hauv Jiangsu Rudong: Raws li phab ntsa ntawm lub pas dej, muaj tag nrho - spectrum LED teeb strips (lub zog ntom ntom 8W / m²) teeb tsa hauv lub voj voog. Kuj tseem muaj qhov programmed dimming uas muab 100% lub zog los ntawm 6:00 txog 18:00 nruab hnub thiab 30% lub zog ntawm 6:00 txog 6:00 tsaus ntuj. Qhov no ua rau lub teeb hauv qab tsis sib xws 88%. Cov cw yug ntom ntom yog nce mus rau 500 cw / m², thiab chav tsev ntau tshaj 15 kg / m³.
Singapore Vertical Farm Aquarium: Los ntawm kev siv kev sib xyaw ua ke ntawm ntau- txheej txheej reflector pawg thiab kho kom pom tseeb LED arrays, 30-meter-siab ntsug aquaculture kem tuaj yeem ua tiav lub teeb sib xws ntawm 92%. Lub coral npog tus nqi mus los ntawm 65% mus rau 90%, thiab tsis muaj cov kab mob algae tshwm sim los ntawm qhov chaw tuag ntawm lub teeb.
