What you’ll be listening to… for the next 15 minutes

•  Where & what is Lake Victoria?briefly…. •  Haplochromine?! Qu’est-ce que c’est Haplochromine? •  …and what’s all the fuss about? •  LVSSP’s mission- what has been accomplished… •  LVSSP’s objectives going forward-

Are the ‘aquarist bits’ still doable? Lake Victoria view Jinja, Uganda

Lake Victoria Geography & Geology Tutorial

•  3 countries comprise border- Uganda, Kenya, & Tanzania •  E African Rift Lake- 1 of 6 sizeable, including Malawi & Tanganyika, occupying shallow plateau between 2 arms of the forked Great Rift Valley •  World’s 2nd largest freshwater lake •  vulnerable to climate change- precipitation driven vs large river inflow, shallow, large surface area compared to volume ratio •  Dry 12-14,000 yrs ago- phenomenal speciation since… 3

Page 4: Renewed Energy to Help Save Darwin’s Dreampond · 2016-02-05 · Renewed Energy to Help Save Darwin’s Dreampond …an SSP attempts to remain hopeful Lake Victoria Cichlid Species

•  >500 LV species- spectacular species radiation

•  group named for genus Haplochromis- by design 80% of Lake Victoria’s biomass

•  nomenclature often pending, hence use of common names (chironym)

•  evolutionary plasticity- rapid response to localized & diverse environmental conditions

•  ~14 trophic guilds recognised

•  Considerable trophic diversity- planktivores, paedophages, parasitivores, fin & scale eaters, to molluscavores, with bizarre dentition stops in between …that’d make dentists swoon!

Traditional Fishery

•  5.4M lake region residents in ‘48 •  ~75% of local protein needs was fishery derived •  Haplochromines accounted for 80% of biomass •  simple fishing gear used •  primarily near-shore fishery •  targeted specific species •  women dominated activity •  no capacity for export to coast •  nutrient poor lake fishery

Modern Lake Fishery

commercial fishing vessel

mixed species catch vs. targeted catch

commercial fishery employment is huge slice of demographic

• Contrast >25m people in LVictoria Basin …2010 estimate • Targets commercially successful Lates niloticus …after its introduction in ’54 • Introduced tilapia spp outcompete endemic tilapia ...and tastes much differently • Focuses on exports- Europe, Middle East, US, & Australia • Beyond financial resources of local population … which results in a net loss of protein & rise of malnutrition •  ‘boomtown environment’- 54,000 boats, cholera, HIV, social upheaval • LVictoria characteristics not conducive to perch population support • Haplochromine drop to 1% biomass • Largest mass extinction event- >65% species lost • Omena (cyprinid) exploded without cichlid predators • Cichlid morphological plasticity- bending to Lake’s condition • Nile perch decline …cannibalism, now! • Pollution/ eutrophication- now ‘nutrient rich lake fishery 'with only 60’ O2 zone in H2O column • Market decline- cholera, heavy metals

Lates niloticus

Reevaluation Time …RAW 2012 •  Been ~ 8 yrs since last thorough

assessment/thrashing •  Evaluate Program Parts

•  Take stock of what is working •  Determine what is not

–  How much bang for the $$ –  Are there efficiencies

•  Collaborations with new Partners •  Open discussions with other AZA

taxa pgm •  Find EAfrican team members with

proven records –  Political upheaval –  Performance marks

Education

• Sharing curricula • Comparing fauna, challenges, successes • Collegial atmosphere • Forging connections and creating bonds • Mutual travel

•  Realities within Program Institution Community: –  culturing vs exhibiting fishes- what are holding system (space use) priorities?

e.g.Loss of Toledo Aquarium’s extensive holding

–  Mycobacteria in LVSSP fishes- threat posed/ naiveté of wild stock to organism –  likelihood of reintroduction in EAfrica- as the prospect diminishes, so does

the appeal of the program to institution resource decision makers –  program participation

•  reduced to 8 priority species in culture, with only 11 institutions participating

–  species plasticity i.e. Are these still the same species after 20 yrs away from Lake?!

–  fitness of program species •  several species no longer minimum viable population MVP, and thus removed from

program

•  Realities in-country: –  lake ecology, mycobacteria, politics, logistics, funding

LVSSP’s Culturing Challenge…never enough resources <sigh>

Oreochromis esculentus on exhibit

LVSSP holding system Toronto Zoo Program’s culturing mandate has challenges: •  LVSSP program species compete with other Rift Lake species for exhibits ..Malawi & Tanganyika • exhibit species will always have higher priority vs those not seen by visitors • when culture scenario placed on visitor path, not as aesthetically engaging, requires a lot of interpretation •  long term holding is rarely able to accommodate all demands/requests LVSSP holding system Toledo Zoo 34
