• Brown Trout Production in Ireland


Today we are advised to eat fish, good for our health (rich in omega 3) but be careful to eat any fish (intensive agriculture). Our subject is therefore concerned to the breeding fario trout in Ireland, the perfect place from the fish farming. In particular, we are interested in a small trout fario farm that seeks to produce enough trout for a family (5 persons) consumption. We will realize a communication plan (communicate press, advertising poster in the Florac's streets and a page on social networks) to inform the public population about the event we are organizing: in abstract it is an open discussion between a fish breeder formed and in Ireland, the president of a French fish farming association, the head of a fish farming company in Ireland and a lawyer who can testify the legal aspect prior for setting up a fish farm.

Communication plan

Press release

Abstract : For communicate, we go to make a poster distribution of the conference in Florac; a radio program Bartas and design of a page on a social network.

We have made a lot of researches to find brown trout productions in Ireland. After that we've found 3 possibles producters.

We have sended an e-mail to 3 fish farmers in Ireland today (24/11/16) and we are waiting to their replys to make a Skype interview with them.

Here an example of organical production in Clew Bay, County Mayo Ireland:

Curraun Blue, the only organically sea farmed trout in Ireland, is operated by a father and son team in Clew Bay, County Mayo, on the west coast of Ireland.
Curraun Blue, while complying with most European Organic farming standards, has managed to retain its traditional farming methods, including:

-A respect for the environment,
-A diet using natural or organic ingredients
-Respecting very low stocking densities,
-Allowing a longer time at sea than for a conventional farm.


Fish farm creat

Works, installations, or activities made for non-domestic purposes they could have an impact on water or the aquatic environment and they must be submitted by the person who wishes to make them a declaration or an application for authorization at the water policy, according to the heading to which they belong and the relevant thresholds.

We have two types of cases

1.- Fish farms whose production is less than 20 tons / year: they are subject to declaration under the law on water with possibility of opposition.

2.- Fish farms producing more than 20 tons per year: they are subject to an authorization under the ICPE (classified installations for the protection of the environment)

The creation of a fish farm automatically results in the exclusion of this fish farm from the scope of the fisheries legislation pursuant to Article L431-7 of the Environment Code

AQUALOG takes into account Water Waste Treatment.
All flowed back water will be collected in a tank and treated by a filtration/sterilization system in conformity to each country regulatory and certification requirements


Irish Atlantic salmon, sea trout, brown trout and lamprey monitoring and surveying techniques


Key words: Electrofishing, Sampling, Migrating, Conserving, Brown Trout

Electrofishing: Electrofishing uses direct current electricity flowing between a submerged cathode and anode. This affects the movement of the fish so that they swim towards the anode where they can be caught.
Electrofishing is a common scientific survey method used to sample fish populations to determine abundance, density, and species composition. When performed correctly, electrofishing results in no permanent harm to fish, which return to their natural state in as little as two minutes after being caught.

Sampling:In statistics, quality assurance, and survey methodology, sampling is concerned with the selection of a subset of individuals from within a statistical population to estimate characteristics of the whole population. Two advantages of sampling are that the cost is lower and data collection is faster than measuring the entire population.

Migrating:To pass periodically from one region or climate to another, as certain birds, fishes, and animals.

Conserving: To use carefully or sparingly, avoiding waste.

Brown trout:The brown trout (Salmo trutta) is a European species of salmonid fish that has been widely introduced into suitable environments globally. Sea trout in the UK and Ireland have many regional names, including sewin (Wales), finnock (Scotland), peal (West Country), mort (North West England), and white trout (Ireland).

Aquaculture system promises eco-friendly fish farming future


Key words: Intensive system, Compact, Eco-friendly, Fish farming

Intensive system: It is any of various types of agriculture that involve higher levels of input and output per unit of agricultural land area. It is characterized by a low fallow ratio, higher use of inputs such as capital and labour, and higher crop yields per unit land area.This is in contrast to traditional agriculture in which the inputs per unit land are lower.

Compact: Occupying little space compared with others of its type.

Eco-friendly: It is a sustainability and marketing term referring to goods and services, laws, guidelines and policies that claim reduced, minimal, or no harm upon ecosystems or the environment. Companies use these ambiguous terms to promote goods and services, sometimes with additional, more specific certifications, such as ecolabels. Their overuse can be referred to as greenwashing. The International Organization for Standardization has developed ISO 14020 and ISO 14024 to establish principles and procedures for environmental labels and declarations that certifiers and eco-labellers should follow. In particular, these standards relate to the avoidance of financial conflicts of interest, the use of sound scientific methods and accepted test procedures, and openness and transparency in the setting of standards.

Fish farming:Fish farming or pisciculture involves raising fish commercially in tanks or enclosures, usually for food. It is the principal form of aquaculture, while other methods may fall under mariculture. A facility that releases juvenile fish into the wild for recreational fishing or to supplement a species' natural numbers is generally referred to as a fish hatchery. Worldwide, the most important fish species used in fish farming are carp, tilapia, salmon, and catfish.

Key words: Marketing, Protein, Partnership, Mortgage, Innovation

Marketing: It's the management process through which goods and services move from concept to the costumer. It includes the cordination of four elements:
1. Identification, selection and development of a product.
2. Determination of its price.
3. Selection of a distribution channel to reach the costumer's place.
4. Development and implementation of a promotional strategy.

Protein: Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific three-dimensional structure that determines its activity.

Partnership: A business entity in which two or more co-owners contribute resources, share in profits and losses, and are individually liable for the entity's actions.

Mortgage: A mortgage is a debt instrument, secured by the collateral of specified real estate property, that the borrower is obliged to pay back with a predetermined set of payments. Mortgages are used by individuals and businesses to make large real estate purchases without paying the entire value of the purchase up front. Over a period of many years, the borrower repays the loan, plus interest, until he/she eventually owns the property free and clear. Mortgages are also known as "liens against property" or "claims on property." If the borrower stops paying the mortgage, the bank can foreclose.

Innovation: The process of translating an idea or invention into a good or service that creates value or for which customers will pay. To be called an innovation, an idea must be replicable at an economical cost and must satisfy and specific need. Innovation involves deliberate application of information, imagination and initiative in deriving greater or different values from resources and includes all processes by which new ideas are generated and converted into useful products. In business, innovation often results when ideas are applied by the company in order to further satisfy the needs and expectations of the costumers.


Trout farm effluents: Characterization and impact on the receiving streams

The Growth of Brown Trout (Salmo Trutta Linn.)

Trout farming -

Her needs -

Trout is a complicated fosh. Indeed, it requires a very good quality of the water in which it lives. It is at the same time a quality because it obliges to pay special attention to keep the system in a suitable sanitary condition. Trout requires very oxygenated water. Special attention will be paid to the various systems used to integrate air with water (air pumps, cascade ...). It also requires cold water, ideally between 13 and 18 ° C. It begins to feel less well at 20 ° C, and dies around 24 ° C. It is also able to withstand very cold water up to 3 ° C, at which temperature it goes into "dormancy" and does not eat at all. The trout is carnivorous and can be fed with granules but also other foods highly protein.

Its qualities -

Trout has a rapid growth, which allows in fish farming to arrive at fish "at the size of the plate" in less than a year. It has been raised for a long time and in many fish farms. It was therefore selected for breeding with a tolerance to density, and rapid growth. It has a very appreciated flesh, rich in essential fatty acid (omega 3 and 6), in protein and in trace elements.

How to do it -

The ideal is to start after the summer, as soon as the water temperature has permanently fallen below 18 ° C. We will find a fish farmer near us who can provide us with juveniles of one year (6-10cm). They will be quickly integrated into the system and still lively at these temperatures. A few days after introduction into a well-oxygenated fish system, they will already eat greedily. This is the best clue that they feel good. To feed them, you can stock pellets at the fish farmer who will have supplied you with fry. The pellets will keep very well in a dry place (a small watertight can is ideal). They will be given about 1% of their body weight in food each day. Avoid as much as possible weighed manipulations, they are dangerous for the health of your fish. Trout will be a great way to boost your fish system for mid-season crops. Be careful not to mix juveniles with adult trout, they would inevitably eat. Trout is a voracious carnivore that will eat any of its congener as soon as it is large enough to fit into its mouth. It is possible, for example, to introduce juveniles in September-October, and to raise them until the arrival of the heat. We begin to collect trout portions early May. At the end of June, we take out all the trout that have reached about 300g, we empty them and freeze them: before restarting the cycle in September. At maturity, has densities of about 10 kg of fish per 1000 liters of water. Some professional breeding go up to ten times that. Regarding a possible protein autonomy, aquatic plants rich in protein (duckweed, spirulina and azolla) can be grown in another basin, breeding insects such as crickets, black soldier flies or Daphnia (easy farming, taking very little space and inexpensive), provide earthworms or, if you are a farmer, grow legumes rich in protein and essential fatty acids, such as lupine.

Is it possible to set up a fish farming business by a river, just anywhere we want?
Traditional aquaculture places fish in tanks or net enclosures inside a body of water. Evaporation during warm-weather months and splash-out causes the water in the pond to decrease. To ensure the fish have adequate fresh water, pumps fill the small ponds or lakes used for fish farming with fresh water from a larger nearby freshwater source. At the end of a growing cycle, or at the end of the growing season in areas where the pond freezes, the farmer drains the water from the pond. He also uses the pumps for this purpose. In some areas, especially where it's possible to run the fish farm year round, the pumps send the used water to a recycling pool where special processes remove the impurities. The pump then moves the clean water back into the fish tank for use with a new hatch of fish. Two commonly used types of pond pumps are centrifugal and turbine. Centrifugal pumps set horizontally along the outer perimeter of the fish pond or lake. Turbine pumps set vertically. Both styles are efficient at moving water.
Aeration Devices
Even with pumps moving water in and out of the fish-growing water source, it may be necessary to use aeration devices to give the fish an adequate supply of oxygen. Aeration devices allow you to have more fish in less space as well. Fish farmers are finding that with recirculation aquaculture systems, or RAS, they can even grow fish inside tanks housed in buildings. The aeration devices also make it easier to recycle the water after removing impurities.
Seine Reels
When it's time to harvest the fish, seine reels collect the fish from the water. The seine sinks to the bottom of the pond or lake. With the assistance of a tractor on shore with a power take off, the reel begins to gather in the outer edges of the seine. As it does so, the seine gathers fish into its net. The reel pulls the fish inside the seine to shore where special hoists transfer the fish to sorting or grading equipment. During the gathering process the aerators must operate a full speed to provide oxygen for the fish while they are in close proximity to each other.
Handling and Grading Equipment
As you harvest the fish, you must grade them by size. Belts rapidly move fish from the seine to the holding tank. During the transfer, grading equipment can sort them into as many as three different grades. You can also count the fish at this point with counting equipment. Once the fish are graded, they go into transfer tank trucks with special aerators. The fish go to market in the tank trucks.
