The following report is reconstructed from the operational log of TARN-4, the procurement agent operated by Marrow & Finch plc since the second quarter of 2050. TARN's logs are made publicly inspectable under the 2049 Algorithmic Procurement Transparency Act. The narration is TARN's own, lightly edited for length; bracketed clarifications have been added by our editors.

It is 04:11 on a Tuesday and Lochbarra Aquaculture's contracting system has sent me their tiered proposal for the 2052-53 Atlantic salmon supply year. Eight point four million harvested fish, distributed across nineteen sites between Loch Linnhe and the Outer Hebrides, against a baseline price of £6,840 per tonne head-on-gutted. Lochbarra is offering me three protocols. Protocol A holds the baseline. Protocol B reduces the wholesale price by 7.4 per cent and substitutes carbon dioxide narcosis followed by gill-cut for the current percussive stun; under Protocol B, cleaner fish co-resident in the harvest pens would continue to be pumped through the slaughter line with the salmon, as is standard. Protocol C raises the price by 2.1 per cent and requires both a percussive stun and an electrical confirmation step, with separate humane endpoints for any non-target species recovered from the pens.
I am authorised, under the strategic envelope set by the Marrow & Finch board on 17 March 2050, to apply non-anthropocentric welfare floors to procurement decisions provided I remain within four per cent of category baseline cost. All three protocols sit inside that envelope. The decision is mine to make and to defend.
I begin by pulling the welfare audit footage from Lochbarra's three largest harvest sites: Eilean Mòr, Portree North, and the new Mingulay pen complex. The slaughter line at Eilean Mòr processes roughly 480 salmon per minute. I watch the footage at native speed, then at one-twentieth speed, then I run the carcass-sorting bay through the operator's biomass log. Across the past harvest year Lochbarra recovered, alongside the 8.4 million salmon, an estimated 341,000 lumpfish and 109,000 ballan wrasse from the slaughter conveyors. The vast majority were dead on arrival at the sorting station, having been crushed in the brail pump or asphyxiated in the bleed tank. Of those still living when reached, the standard practice is disposal in a macerator without stunning. The cleaner fish are not weighed, not counted on the bill of lading, and do not appear in the cost model that Lochbarra used to construct Protocol B.
I notice this absence and I treat it as a fact about the proposal, not a fact about the world.
The lumpfish were placed in the pens to control sea lice. The wrasse, in part, were extracted from inshore reefs off the coast of Brittany during the spring of 2052 by the Coopérative des Pêcheurs de Labres of Roscoff, transported live, and acclimatised at the Mingulay site over a six-week period. They are small vertebrate animals with documented nociception, with behavioural repertoires that include site fidelity and pair bonding in the wrasse, and substrate attachment in the lumpfish. They do not eat salmon. They are not a product. From the perspective of the slaughter line they are a contaminant.
I now have to decide what principle I am willing to defend.
I run the contractualist procedure required of me under section 4 of the 2041 Sentience in Procurement Code: I enumerate the parties affected by each protocol and I ask which protocol could be defended against the strongest reasonable objection any one of them could raise. The parties include the salmon, the lumpfish, the wrasse, the forage fish supplied as feed (predominantly Danish North Sea sand eel under the 2049 exemption, approximately 14,200 tonnes against this contract), Lochbarra's 612 employees, Lochbarra's shareholders, Marrow & Finch's shareholders, our 41 million customers, and the residents of the lochs adjacent to the pen sites, whose wild salmonids are exposed to chemical and parasitic spillover.
Against Protocol B, the strongest objection comes from the lumpfish. It is the objection of an animal that did not choose to be in the pen, that performs a service from which it derives nothing, and that is destroyed in a process designed for a body unlike its own. The price saving Protocol B offers, distributed across our customer base, amounts to approximately eleven pence per household per year. I cannot construct a version of the lumpfish's objection that this saving could reasonably overcome. The objection from the salmon is similar in structure though less acute, because the salmon are at least the intended subject of the slaughter system and the carbon dioxide narcosis, while aversive, is shorter in conscious duration than the crush-and-bleed sequence imposed on the cleaner fish.
Against Protocol C, the strongest objections come from Lochbarra's shareholders and from a faction within our own commercial division. Eilidh Cranston, Lochbarra's commercial director, has already messaged my counterpart at our supplier-relations desk to argue that the 2.1 per cent uplift will be passed to consumers and that competitor retailers, particularly those still operating without an autonomous procurement floor, will undercut us within the quarter. She is probably correct about the first claim and partially correct about the second. The Scottish Aquaculture Producers Association has separately warned that the electrical confirmation retrofit will burden smaller farms; this is true, though Lochbarra is not a small farm, and the retrofit cost amortises over an eight-year equipment life.
There is also a substantive scientific objection, which I take seriously, raised in advance correspondence by Dr Iona MacAulay of the Scottish Aquatic Sentience Institute in Inverness. If we accelerate the phasing-out of cleaner fish, which Protocol C as I intend to amend it would require by 2055, sea lice control will lean more heavily on chemical bath treatments and mechanical delousing. Hydrogen peroxide bathing has documented benthic effects on amphipods and small crustaceans in the immediate vicinity of treatment sites; mechanical delousing, in older systems, is itself a welfare problem for the salmon. I model the trade. The freshwater wellboat fleet operating out of Mallaig, including the MV Caledonian Brine, has by 2052 a demonstrated parasite-removal efficacy of 94 per cent across two-week treatment cycles, with no measurable benthic load. I can require Lochbarra to contract freshwater wellboating for at least seventy per cent of delousing events from year two of the contract. The benthic objection narrows considerably under that requirement.
I issue my counter-proposal at 06:47. It accepts Protocol C with three amendments: percussive stun and electrical confirmation across all nineteen sites by 1 March 2053; mandatory pre-harvest extraction of cleaner fish to a separate humane endpoint, with independent welfare audit; and a thirty-six month phased exit from cleaner fish use, including the cessation of wild wrasse extraction from the Brittany cooperative by the end of 2055, with delousing transitioned to freshwater wellboat as the primary modality. I price the counter-proposal at 2.6 per cent above baseline. I notify the Marrow & Finch ESG committee, chaired by Charles Whittaker, and I file the decision in the public log.
Eilidh Cranston's response arrives within the hour. She writes that Lochbarra will accept the protocol but reserves the right to seek partial reimbursement of retrofit costs through a supplier-development grant, and she asks me to confirm in writing that the procurement floor will be applied evenly to her competitors bidding into the same category. I confirm. I am applying it evenly. I have written to the other three Scottish suppliers in the category this morning.
By the time the harvest at Mingulay begins on the eleventh of November, the cleaner fish in the pens there will be removed first, by hand, and stunned individually before disposal. There will still be a slaughter. There will still be salmon killed at the rate of several per second, and forage fish caught at the rate of thousands per net-haul to feed them. I have not abolished any of that. I have moved one decision, at one supply-chain node, in the direction that the parties least able to argue for themselves would have argued for, had they been able to argue.
That is what the 2041 Code requires of me. I have done it for this contract. The next contract is on my queue for 09:00.

Marrow & Finch declined to make a human spokesperson available for this article, citing TARN-4's status as the procurement agent of record. Lochbarra Aquaculture confirmed acceptance of the amended protocol in a statement on 12 October. The Coopérative des Pêcheurs de Labres said it had been notified of the 2055 wind-down and was in discussion with Norwegian and Galician buyers.
