AIM (Aquaculture Information Management)

Aquaculture production is a detailed process with many elements.  Here are some basic elements associated with raising fish.

Aquaculture Information Management

Aquaculture Information Management (AIM) is a database system which provides data entry masks and file management for  60 files.   It is designed to store data, perform simple calculations and interface with spread sheets (see SAP).

The goal of this software is to organize production data in order to better manage and simulate an aquaculture installation.   As aquaculture becomes a more visible activity it is vulnerable to mis-information, regulations and controversy.  Detailed information can resolve many questions and provide assistance for consensus building.

The following “screen shots” illustrate the application and provide information concerning production data and methods.


Main Menu (top)

Most aquaculture installations have basic functions.  Although the names and procedure can vary, the functions remain similar. We grouped these functions and tasks into :

Installation         – Defining a site and its basic material
Daily                – Biological Production
Art/Rot/Alg      – Production of artemia, rotifers, algae,
Reproduction   – Reproduction processes
Occasional       – Occasional and non-production activities
Simulation       – Simulation options

 

 

 

 

 

 

Food Details Menu


File Control (top)

All data entry mask are accompanied by a control window, shown below.  This menu permits the users to perform operation upon the data file.

Operations include : Add – add a record, Beg – go to beginning of file, Copy – copy the current record, Del – delete current record, End – go to the end of the file, Find – locate and list specific records, Next – skip to next record, Prev – skip back one record, Quit – quit and return to main menu.




Installation (top)

An installation is defined with basic information (i.e. name, address, legal status, geographical location, etc.) which usually remains static.




Tanks (top)

An installation is also defined by the number and type of tanks, cages, circulation systems etc.  Tanks can be added, changed or deleted from an installation.  A tank can have an independent circulation system or be grouped with other tanks and be part of circuit.  If the tank is part of a circuit it may be the tank from which measurements are taken.




Daily (top)

Daily activities, or production has several components.  Larva, Weaning, Breeders, Deaths, Miscellaneous, Tanks and Units.

Much of the daily information can be provided by in circuit sensors which transmit data directly to the computer for incorporation into the database.


Larva – Daily (top)

Daily Larva contains information about the larva production.  Data like “Physio-Chemical”, “Feeding” and “Opening of the Tank” is grouped.

Larva_daily.gif (13067 bytes)


Larvae – Sample (top)

Installation personnel sample larva (often daily) in order to control health and provide indications for feeding and growth.  In the screen, individuals which are sampled can be uniquely identified or grouped into a lot.  Calculations are performed in order to provide an overview of  the groups health and performance.

Sample_daily.gif (11551 bytes)


Weaning (top)

The weaning of larva from live food to pellets is performed over a period of several days.  Artemia, Rotifers and other live foods are slowly replaced with dry food.  This screen and associated data file follow the evolution of this process.

Weaning_daily.gif (11439 bytes)


Breeders  – Initial (top)

Breed stock are initialized by placing them in a tank or by moving individuals from one tank to another.

Initial_breeder.gif (9961 bytes)


Breeders – Daily (top)

Breeder are fed a varity of foods, both live and processed plus other daily activities.

Daily_breeder.gif (10404 bytes)


Deaths (top)

Deaths can occur in any tank.  The above screen is for recording all deaths, no matter where they occur.

Daily_death.gif (5533 bytes)


Enrichment (top)

If a food supply is enriched with vitamins or other products the information (time, tank, etc.) is recorded to the food enrichment data file.

Enrichment.gif (5681 bytes)


Miscellaneous (top)

This screen is provided to record observations which are general in nature.


Miscellanious.gif (6728 bytes)


Daily – Tanks (top)

Data unique to a tank, as opposed to a tank in a circuit are entered into the database using this screen mask..

Daily_tanks.gif (8777 bytes)


Units (top)

Units, or circuits are a group of tanks connected to each other, usually via a water circuit.  A unit usually produces the same animals.  In our example there are 8 unit types : Breeders, Incubation, Larvae, Weaning, Pre-growing, Artemia, Rotifers and Algae.

Daily_units.gif (16612 bytes)


Artemia / Rotifers / Algae Production (top)

Many aquaculture farms produce live foods for their own larvae.  The production of these micro-organisms is a process, not unlike raising fish.  For example, artemia production requires several steps, decapulation, enriching their food supply, hatching and distribution to the larva production tanks, for consumption.


Artemia – Decapulation (top)

The decapulation of artemia requires several steps depending upon different factors including the artemia type (A0 or A1), supplier and cysts per kilogram.

Artima_Decap.gif (8526 bytes)


Artemia – Enrichment (top)

Enrichment of artemia entails controlling the environment and noting what type of enrichment is used and under what conditions.

Artima_enrich.gif (10144 bytes)


Artemia – Hatching (top)

Sampling the Artemia during hatching provides data concerning the number hatched, the hatching rate and time they occurred.

Artima_hatch.gif (9599 bytes)


Artemia – Request (top)

This screen is used to “order” artemia from the production center.  Commands for artemia within an aquaculture installation are centralized so those responsible for artemia production can anticipate demand.

Artima_request.gif (8620 bytes)


Artemia – Supplies (top)

This form is use as a “bill of delivery” for recording the delivery of artemia to the different production systems.

Artima_supply.gif (6812 bytes)


Rotifer – Enrichment (top)

Rotifers, like artemia, are produced for larva consumption.   The production of these micro-organisms is recorded using the following two screen masks.

Rotifer_enrich1.gif (10581 bytes)

Rotifer_enrich2.gif (10452 bytes)


Rotifer – Daily (top)

Several processes can be performed during the production of rotifers :  they are sampled, collected, the environment controlled, etc.  Productions is either Semi-continuous or batch.

Rotifer_daily.gif (14016 bytes)


Algae (top)

Reproduction (top)

Reproduction is divided into several steps : induction of females,   spawning, collection of eggs and filling the incubator.

Collecting the eggs and filling the incubator is required as eggs are spawned thus a system of sub-groups or “sub-batch numbers” is designed in order to form a “batch number”.


Induction (top)

The induction process is recorded for posterity and management.  Females are usually moved to an induction tank where they can be observed during the spawning.

Induction.gif (10024 bytes)


Spawning (top)

As eggs are produced observations and results are recorded using this screen mask.  The time of the observation is noted as the situation evolves.  Eggs are collected and processed (discarded, sold or incubated), those that are retained are assigned a sub-batch number.  Once the incubator is full, the group or lot, is assigned a batch number which is used to follow the lot throughout the production cycle.

Spawning.gif (14470 bytes)


Fill Incubator (top)

As the eggs are collected they are placed in an incubation tank.  As eggs hatch larva are controlled to provide an accurate data concerning the spawning and hatching processes.  The first screen is used to store data concerning the incubator and the eggs while the second screen mask is concerned with the hatching and survival of the larvae.

Fill_incubater1.gif (13485 bytes)

Fill_incubater2.gif (9958 bytes)


Occasional (top)

Occasional and non-production activities groups several activities.  The movement of fish from one tank to another, diagnosis and treatment .  Also   products and services purchased by the installation such as FoodEnrichmentsMedicinesVitaminsDisinfectants and  Small Material. This section also stores information concerning the installation’s infrastructure and functioning such as Fixed Costs, Salaries and   Investments.


Movement (top)

The movement of fish from once tank to another is a common problem as it often entails separating and mixing of different lots. Often a new lot is formed from selected individuals of different lots based upon their size, mean weight or other criteria.  Tracking these operations is simplified using unique batch numbers for source and destination.

Movement.gif (8986 bytes)


Diagnosis (top)

The diagnosis file records data concerning the evaluation of health problems.  Case numbers are assigned, individuals are sampled, diagnosed, values recorded and comments noted.

Diagnostic.gif (10025 bytes)

Simulation (top)

The object of a database is to store production data in order to better understand and manage an aquaculture farm.  An important tool is the ability to simulate production into the future without experimenting with current production processes.   This section is designed to illustrate how one might simulate an aquaculture farm using real production data combined with various scenarios and models.   The goal is to develop a tool which could  signal potential problems and obstacles before they limit production and reduce profit.


Control (economic) (top)

Control is designed to activate or dis-activate major components of the simulation.  For example a simulation could include taxes, subventions, investments, etc.  Or just calculate the growth rate and food cost of a lot.
