5. Shawarwarin Magani & Dabarun Shawarwari

Bitan ya ƙare da kira ga aiki wanda ya ta'allaka ne akan:

1. Ingantaccen Tattara Bayanai: Aiwatar da daidaitaccen sa ido na kimiyya akan kamun kifi, ƙoƙari, da kamun kifi ba da gangan ba a duk faɗin yankin, mai yuwuwa ta amfani da sa ido na lantarki da aikace-aikacen kai rahoton masunta.
2. Haɗin Gudanarwa & Haɗin Masu Ruwa da Tsaki: Haɓaka tsarin gudanarwa na haɗin gwiwa wanda ke haɗa ilimin masunta da tabbatar da sayen su.
3. Gina Ƙarfin Yanki: Ƙarfafa cibiyoyin kimiyya da gudanarwa na gida ta hanyar horo da rarraba albarkatu.

6. Bincike mai zurfi & Ra'ayin Ƙwararru

Muhimmin Fahimta: Wannan bita yana fallasa gazawar tsarin tsarin a cikin SWIO: ana ƙoƙarin gudanar da tsarin zamantakewa-muhalli mai rikitarwa tare da kayan aikin bayanai na kafin masana'antu da tsarin mulki. Takardar ta gano matsalar daidai—matsanancin rashi na shaida—amma maganin da aka ba da shawara ya dogara ne akan matakin haɗin kai na yanki da ƙarfin cibiyar da a halin yanzu ba ya wanzu a cikin ma'aunin da ake buƙata.

Matsalar Hankali: Hujjar tana da ma'ana: bayanai marasa kyau → rashin fahimta → gudanarwa mara tasiri → sakamako mara dorewa. Takardar tana bin wannan sarkar sanadi yadda ya kamata, tana amfani da raunin nau'ikan K-zaɓaɓɓe a matsayin mai haɓaka ilimin halitta na matsalar.

Ƙarfi & Aibobi: Babban ƙarfinsa shine cikakken iyakarsa, iyakar yanki da kuma ingantaccen kimanta talauci na bayanai. Babban aibi, duk da haka, shine ɗanɗanon sa na hanyoyin aiwatarwa da shingen tattalin arziki na siyasa. Yana ba da shawarar "kyakkyawan mulki" da haɗin kai amma yana ba da ƴan dabarun zahiri don shawo kan masu ruwa da tsaki, rashi na kuɗi, da rashin motsi na siyasa waɗanda ke siffanta gudanar da kamun kifi a yankuna da yawa masu tasowa. Idan aka kwatanta da tsalle-tsalle na fasaha a wasu fagage (misali, amfani da Cibiyoyin Adawa na Haɓakawa (GANs) kamar CycleGAN don ganewar nau'in halitta da sa ido kamar yadda aka tattauna a cikin Zhu et al., 2017), maganganun da aka ba da shawara a nan suna jin ƙari.

Fahimta mai Aiki: Ga masu aiki da masu ba da kuɗi, fifikon nan take ya kamata ya zama saka hannun jari a cikin bututun bayanai masu sauƙi, masu amfani da fasaha. Maimakon jira cikakken sa ido na gwamnati, ya kamata a ba da goyon baya ga ayyukan gwaji ta amfani da:
1. Jiragen marasa matuki da hotunan tauraron dan adam (wanda aka yi wahayi daga aikace-aikacen ƙungiyoyi kamar Global Fishing Watch) don taswirar ƙoƙari da kansu.
2. Ganewar hoto mai taimakon AI akan wayoyin hannu don masunta su yi rajistar kamun kifi ba da gangan ba, yana rage dogaro da ƙwarewar taxonomy.
3. Tsarin Blockchain ko tsarin rubutu mai tsaro don takaddun kamun kifi don inganta bin diddigin abubuwan da suka faru da yaƙar kamun kifi na IUU, wani batun da ke da alaƙa. Manufar dole ne ta zama don samar da bayanai "mai kyau isa" cikin sauri don sanar da yanke shawara na matakin rikici, yayin gina tsarin cibiyar na dogon lokaci da takardar ke hasashen.

7. Tsarin Fasaha & Hanyar Bincike

Don matsawa daga labari zuwa kimantawa na ƙididdiga, ana buƙatar daidaitaccen tsarin bincike. Babban sashi shine ƙirar raunin yawan jama'a. Wannan sau da yawa yana amfani da tsarin Matsakaicin Cirewar Halitta (PBR), wanda aka daidaita don kamun kifi ba da gangan ba. PBR yana ƙididdige matsakaicin adadin dabbobin da za a iya cire su daga yawan jama'a ba tare da haifar da raguwa ba:

$\text{PBR} = N_{min} \times \frac{1}{2} R_{max} \times F_r$

Inda:
$N_{min}$ = Ƙananan ƙididdigar yawan jama'a
$R_{max}$ = Matsakaicin ƙimar girma na ka'idar
$F_r$ = Factor farfadowa (yawanci 0.1-1.0)

Duk da haka, a cikin mahallin SWIO, $N_{min}$ yawanci ba a san shi ba. Saboda haka, tsarin saita fifiko dangane da haɗarin dangi ya fi dacewa. Wannan na iya amfani da hanyar ƙima ta ƙima ta ƙima ta ƙima (ERA):

$\text{Maki na Haɗari}_{nau'in, kamun kifi} = \text{Fitowa} \times \text{Sakamako}$

Fitowa aiki ne na haɗuwar sararin samaniya/lokaci da saukin kayan aiki. Sakamako aiki ne na samar da ilimin halitta na nau'in (sabanin alaƙa da zaɓin K) da matsayin yawan jama'a na yanzu.

Mataki 3 - Fihirisar Sakamako: Dugongs suna da ƙananan $R_{max}$ (~5% kowace shekara). Matsayin IUCN yana da rauni. Sanya babban maki sakamako: 3.
Mataki 4 - Maki na Haɗari: $\text{Maki na Haɗari} = 2 \times 3 = 6$ (a kan ma'auni na 0-9). Wannan yana nuna Babban Fifiko don bincike da ragewa (misali, gwada pingers na sauti ko gyara bayanan raga).
