By the way, how much is the fish?*

By Cornelia Kreiss:

To produce a good seafood product according to ecological, welfare and human health aspects we also have to consider the economic side of the coin. The use of sustainable alternative feed, close monitoring of the production conditions or the valorisation of side-stream products is beneficial for a more sustainable production, but will also come at a cost. How high is this cost? Which production benefit or who (the consumer?) will compensate for these costs? What about the whole sector impact?

These are very important questions for farmers and the seafood industry in general, which we seek to answer within GAIN. In order to do this on farm-scale we use a so-called “typical farm approach” implemented by the agri benchmark network headed by the Thünen Institute in Germany. This is a micro-economic tool which allows to portray the typical production of a farmed species according to real costs, techniques and other inputs: all of it in great detail. In the end we can estimate, which market returns per kg fish should be achieved in order to stay (as) profitable (as before)!

Sustainable production methods themselves already benefit the farmer, resulting in better quality fish that needs less feed to grow to the same size, or achieving higher water quality which might also allow for higher stocking densities. However, such benefits do not always outweigh the full costs that adaptations towards sustainable production might involve. As long as follow-up costs of environmental impacts are not part of the market price (which is admittedly not an easy task to determine!), price differences are at the expense of sustainable products and need a transparent justification.

Originating from Germany, where public awareness and willingness to pay for more sustainable seafood products is higher than in other countries, I am convinced that a good market transparency is the way forward and I am excited to be part of this aim in combination with more sustainable seafood production within GAIN.

*The fish bought by the electro trashers band “Scooter” in the 1990’s and being the name giver for their song “How much is the fish”, cost 3.80 Deutsche Mark and supposedly lived for at least 18 years, which seems to be a quite good deal!

Beer from oysters

By: Joshua Kyle

Walled City Brewery is an independent brewery in Londonderry which prides itself in providing patrons with a ’taste of the North West‘ by crafting local, authentic, premium quality, flavoursome beer and food. Inspired by Guinness’ suggested serving of oysters with stout, the challenge was laid down to the brewers to develop a beer using local Lough Foyle oysters and so Foyster Stout was born.

As with all great challenges, research was needed before jumping into the beer-making by looking to other breweries such as Maine’s ’Out-To-Sea‘ imperial stout in the USA or Dublin’s own Porterhouse’s beer, ’Oyster Stout‘.

A sustainably sourced supply of oysters was required for the beer and that’s why we selected the Lough Foyle Irish Flat oyster—the Loughs Agency, operated jointly by Ireland and Northern Ireland, has worked extensively on this species, as have members of the GAIN team. The oysters were sourced from licensed farmers—it is vital for us and for our customers that we use the best ingredients from sustainable suppliers.

The use of the oyster had a dual purpose in the brewing process. Firstly, the flesh was used in the mashing process which extracts natural sugars—the flesh gives a fantastic marine essence to these sugars. Secondly, the shells contain a high amount of calcium carbonate which is used as clarifying agent of the beer. This ensures every part of the oyster is used and nothing is wasted.

The Walled City Brewery launched the beer on 12th October, 2019 which was widely well received. It will be going on sale as a seasonal beer and Foyster Stout will be available in selected bars and restaurants in the city. We’re grateful to the Loughs Agency for their support in our development of this new beer which will help raise awareness for the Flat Oyster.
