Solutions · Fisheries & aquaculture

No forest, no fishery. We fix the first part.

Abalone, rock lobster, finfish and dozens of smaller species spend the fragile start of their lives in kelp. When a reef flips to urchin barrens, recruitment collapses years before quotas catch up. Tidewright rebuilds that habitat at scale — and structures programs so the operators who depend on the reef help run it.

The situation

The problems we hear about first.

Barrens spread faster than any cull

Urchin barrens are a stable, low-value state. Diver culling alone rarely keeps pace across a coastline; without reseeding, cleared reef stays empty.

Recruitment fails quietly

Juvenile habitat loss shows up in catch data years late. By the time quotas fall, the reef has been unproductive for a long time.

Fishers are locked out of restoration economics

Historically, restoration money flowed around working boats, not through them — even though operators hold the local knowledge and the vessels.

Restoration claims don’t stand up at the co-op meeting

Operators have heard promises before. What changes minds is survival rates, fish counts and catch-adjacent evidence published where everyone can see it.

The program

How we work together.

Habitat that recruits, verified in public

We reseed reef with Holdfast lines matched to local kelp genetics and publish juvenile fish and invertebrate surveys on Canopy Ledger — the numbers your members will ask for, where they can check them.

Culling contracts plus reseeding, as one job

Where urchins are the bottleneck, we contract local dive crews for targeted culling and reseed the same season — so the reef doesn’t flip back before the kelp establishes.

Work on the water, not just evidence of it

Local vessels run support, survey and harvest legs under Tidewright contracts. Restoration on your coast should appear on your crew’s payslips.

A new revenue line beside the fishery

Adjacent Harvest longline farms buy seedstock, gear handling and processing from local operators — and their fixed revenue share funds the restoration that feeds the fishery.

contracting model so operators earn from the restoration itself

Figures describe Tidewright’s fictional operating standards and illustrative program outcomes.

“I was the sceptic at the co-op meeting. Then I got paid to cull urchins on a reef I’d written off, and two winters later I was showing visiting crews the kelp. I still read the survey data before I say anything — which they publish, so I can.”

Ways in

Three ways to start.

Reef recovery contract

Targeted urchin culling plus same-season reseeding on barren-ground reefs, run with local dive crews under one contract.

Harvest partnership

Operators supply vessels, gear handling and processing to adjacent longline farms — and gain a stake in the revenue that funds restoration.

Data cooperation

Fishers’ local knowledge shapes site selection; in return, survey data and recruitment counts are shared back to the co-op in plain formats.

Questions

FAQ for fisheries & aquaculture

Will restored kelp beds be closed to fishing?
Access rules are set with the co-op and the regulator before we touch the water. Most Tidewright sites are designed for continued sustainable harvest — the forest is there to feed the fishery, not to fence it off.
How fast does a restored reef show up in recruitment?
Kelp canopy typically establishes within two seasons on suitable ground; invertebrate and juvenile fish responses follow over the following years. We publish site-level survey data so you can watch the trajectory rather than take our word for it.
Do Harvest farms compete with wild capture or existing leases?
No. Farms sit adjacent to restoration sites on their own leases, under the same provenance rules as the restoration itself, and are excluded from credited restoration areas. Local operators are first in line for farm contracts.
What does the co-op have to commit?
Time and knowledge up front; contracts pay for the work done. A typical engagement starts with a paid knowledge-sharing and site-mapping exercise, so even the exploratory phase is not volunteer labour.
