This is an exhaustive inventory of **equipment necessary for aquarium and laboratory configuration** for executing **ichthyological research**, specifically in nutritional, physiological, and toxicological investigations.
## 🐟 **A. Aquarium Setup Apparatus**
### **1. Aquariums and Equipment**
* Glass or acrylic aquaria (different capacities: e.g., 50–100 L) * Tank supports or shelving units * Aquarium coverings or lids * Dividers (for partitioning or isolation inside aquaria)
### **2. Hydric Management**
* Water storage tanks (for aged or dechlorinated water)
* Water conditioner/dechlorinator * Submersible water pumps (for circulation purposes)
Air pumps and aeration stones
Airline tubing and valves
* Filtration systems (sponge filters, canister filters, etc.)
* Thermometers (digital or mercury-free analog) * Heaters or chillers (according to species temperature needs)
* Syphon hoses (for maintenance and water alterations)
* Receptacles and vessels (for water management)
---
## 💧 **B. Instruments for Monitoring Water Quality**
* Digital pH meter or pH testing kits * Dissolved Oxygen (DO) meter * Ammonia, nitrite, and nitrate testing kits * Total Dissolved Solids (TDS) meter * Conductivity meter * Salinity refractometer (for brackish or marine species)
* Test kits for water hardness (GH/KH) * Thermo-hygrometer for laboratory environment monitoring
---
## 🍽️ **C. Nutritional Administration and Dosage Preparation**
Analytical balance (precision: 0.001 g or superior)
* Mixing basins and spatulas (stainless steel or glass) * Gelatin or agar for binding feed
* Pelletiser or manual extruder * Drying trays or dehydrator * Refrigerator (for feed storage)
* Syringes and pipettes (for liquid dosage preparation or injection) * Blenders and homogenisers (for mixing feed or dosing solutions)
---
## 🧪 **D. Laboratory Equipment**
Digital weighing scale for measuring fish body weight
Digital callipers (for measuring the length of fish)
Dissection instruments (forceps, scissors, scalpels)
Dissection tray and board
* Centrifuge (for the processing of blood or tissue samples)
* Compound and stereo microscopes * Spectrophotometer for biological experiments
* Microplate reader (optional, for ELISA or enzymatic activity)
pH strips and buffer solutions for calibration
Sample vials and test tubes (glass or polypropylene)
Laboratory glassware (beakers, flasks, graduated cylinders)
---
## 🧬 **E. Discretionary Instruments for Enhanced Analysis**
* Histological apparatus (fixatives, microtome, staining kits) * Haematological collecting apparatus (capillaries, anticoagulant vials)
Freezer (at -20°C or -80°C for sample preservation)
* Data recording/statistics software (Excel, SPSS, R) * Image analysis software (if employing microscope)
---
## 🧯 **F. Safety and Maintenance**
First aid kit, lab coat, gloves, goggles, fish anaesthetics (e.g., MS-222 or clove oil), fire extinguisher, spill kits, and disinfectants (e.g., potassium permanganate, chlorine).
---
## 📋 **G. Documentation and Labelling**
* Permanent markers and weatherproof labels * Logbooks for tank data, water quality, feeding, and mortality * Laminated charts for daily monitoring sheets
---
### ✅ **Discretionary Components for Automation and Expansion**
Automatic feeders (for scheduled feeding)
* Automated water exchange system * Closed-circuit television or webcams (for remote surveillance) * Barcode system (for sample monitoring)
