Bacteria play several important roles in an aquaponics system. Certain types of bacteria convert toxic ammonia from fish waste into less toxic nitrites and then nitrates that plants can use as nutrients. The document outlines the nitrogen cycle process, where Nitrosomonas bacteria break down ammonia into nitrites, and Nitrospira bacteria then break down nitrites into nitrates for plant consumption. A diagram is provided to illustrate this nitrogen cycle between fish waste, bacteria, and plant consumption of nitrates in an aquaponics system.

Our probiotics have three main benefits:
1. They have good adhesion to intestinal mucosa which helps them inhibit pathogens like E. coli and Salmonella.
2. They produce enzymes that break down nutrients and inhibit the growth of pathogens.
3. Our products can produce enzymes, reduce water pollutants, and have high salinity, pH, chlorine, and biocide tolerance making them better for survival in aquaculture.
Pisces
The document proposes the concept of Pisces, which are robotic fish designed to be part of smart home interior design systems. Pisces aim to address issues with traditional fish breeding such as water pollution, ecosystem disruption, and habitat loss from abandoned fish. Pisces would have automated swimming, wireless charging, surveillance capabilities and remote control to monitor homes and provide aquarium therapy benefits without risking real fish. Integrating Pisces into interior design could create eco-friendly living spaces while maintaining the aesthetics and wellness effects of aquariums.

¡El Optimismo Es Todo Un Arte!
Este documento presenta varias citas que enfatizan la importancia del optimismo y una actitud positiva. Resalta que el optimismo permite ver oportunidades donde otros ven desastres, y que hablar de cosas alegres y positivas puede mejorar el estado de ánimo de los demás. También enfatiza que enfocarse en las ganancias en lugar de las pérdidas y valorar las propias cualidades en lugar de envidiar a los demás puede llevarnos a una mayor satisfacción.
Lesson 12 plant classification
There are seven main levels of classification for organisms - kingdom, phylum, class, order, family, genus and species. The document then classifies strawberries at each level, noting that strawberries are classified in the plant kingdom, Angiosperms phylum, Magnoliopsida class, Rosales order, Rosaceae family, Fragaria genus and that there are many strawberry species.
Lesson 24 sustainability
An aquaponics system addresses sustainability issues by using resources more efficiently. It uses less water than traditional farming since the fish wastewater irrigates the plants in a closed-loop system. It also uses less land since fish and plants can be grown together vertically. By growing food in an aquaponics system, it reduces the need for deforestation to use land for traditional agriculture.
Lesson 16 fish metabolism
When fish are given food, their bodies break it down to extract nutrients and energy for vital processes like growth, movement, and wound healing. Plants get their energy from sunlight while animals obtain energy by eating food, which provides necessary nutrients like fats, carbohydrates, and proteins. Any food remnants that the body cannot use are expelled as feces.
Lesson 19 media and soil
The document discusses the purposes that soil and other planting media serve for plants. It notes that media provide structure to help plants stay in place, a habitat for beneficial bacteria and worms to live near the plants' roots, and a means to trap nutrients from animal waste as well as water and air close to the roots. Media also act as a protective shield for roots against large temperature changes. The key is choosing a media that fulfills these roles of structure, supporting microbes and animals, nutrient retention, and temperature regulation for optimal plant growth.

Lesson 22 wetlands
Wetlands are areas where land and water meet, with wet soil for at least part of the year, providing habitat for organisms adapted to living in wet conditions. Wetlands are compared to aquaponics systems, as both involve a relationship between land, water, and living things that thrive in wet environments. Wetlands and aquaponics also demonstrate how ecosystems can integrate land and water resources.
Lesson 17 fish care
To keep fish happy and healthy, only feed them the amount they can eat in 5 minutes, fill the tank often and avoid overfeeding which can pollute the water. Fish, like humans, can get stressed from factors like cold water, overcrowding, and being caught too frequently. Proper care is needed to maintain a healthy environment for fish.
Lesson 7 aquaponics
This document outlines several benefits of aquaponics including growing both fish and plants together in a symbiotic system, producing fresh organic produce and fish locally with minimal water and no chemical usage or shipping needs, while also serving as an educational and enjoyable activity.

Lesson 11 plant life cycle
The document outlines the 7 phases of development that a typical plant goes through over its lifetime:
1. Seed - The plant starts as a seed planted in the ground.
2. Cotyledon - A small part of the plant emerges from the seed while still underground.
3. Seedling - The young plant reaches the surface as a small seedling.
4. Vegetative - The plant grows to its full size but does not yet flower or fruit.
5. Flowering - The plant produces flowers to attract pollinators.
6. Fruiting - The plant bears fruit containing seeds for new plants.
7. Death - All plants eventually die at the end of their natural lifecycle
Lesson 13 dissolved oxygen
Fish use their gills to extract oxygen from water. Oxygen dissolves into water from air, similar to how sugar dissolves. Water movement from waves, aerators, or aquaponic plant systems helps mix the oxygen throughout the water. When water boils, the heat causes dissolved oxygen to escape from the water.
Aquaponics and Renewable Energy
This document discusses aquaponics and renewable energy systems. It describes an aquaponics social enterprise that provides components and complete systems. Profits fund research and development. It then explains how aquaponics integrates aquaculture and hydroponics in a low-input, high-output system. A case study of a project called ABLE integrates aquaculture, hydroponics greenhouses, biomass heating, and other renewable energy options like heat pumps. The system is designed for education and as a scalable commercial model.

Amezcua - Prevention Chemical
Low-income groups have fewer non-communicable diseases as they cannot afford processed foods containing chemicals. Several organizations aim to remove cancer-causing chemicals from foods and consumer products by 2013. The recommended ways to detoxify include drinking spring water or natural juices. Spring water is the purest form of water containing healing properties when examined under a microscope. Modern drinking water treatment involves chlorination and fluoridation, which reduces the water's natural structure and minerals. The BioDisc product can be used at home to structure water similarly to spring water, providing health benefits. It is made of technologically bonded natural minerals and emits bioenergy and biophotons that restructure molecules.
Fish and Bacteria.ppt
This document describes the process of aquaponics, which combines aquaculture and hydroponics. In an aquaponics system, fish waste provides nutrients for plants and bacteria that clean the water for the fish. Ammonia from fish waste is broken down by bacteria into nitrites and then nitrates, which plants use as fertilizer before the clean water returns to the fish. An aquaponics system mimics natural nutrient cycles to allow for closed-loop food production with minimal water and fertilizer use.

In an aquaponics system, fish waste provides nutrients for plants and bacteria that remove toxins from the water, which is then recirculated to the fish. Bacteria convert fish ammonia waste into nitrites and then nitrates, which plants use as nutrients to grow. The plants help filter the water for the fish, creating a symbiotic, closed-loop ecosystem that uses less water and fertilizer than traditional agriculture.

Starting a biofilter involves seeding nitrifying bacteria onto the biofilter media to convert toxic ammonia and nitrite waste produced by aquatic organisms into non-toxic nitrate. The process involves adjusting water chemistry by adding alkalinity and ammonia sources, then introducing nitrifying bacteria from an established system or commercial preparations. Water quality is monitored as the bacteria colonies develop, seen by ammonia levels peaking then declining as nitrite levels rise and fall, indicating the biofilter is established. Once nitrite levels decline, stocking or increased feeding can begin. Temperature, media selection, and aeration can impact bacteria growth rates during biofilter start-up.
The ornamental fish industry(iranocichla persa vs iranocichla hormuzensis)
The document discusses the ornamental fish industry, including the history of aquariums and keeping fish as pets. It describes different types of aquariums (freshwater vs. saltwater), the nitrogen cycle that occurs in aquariums, necessary equipment, and sources of aquarium fish. It also provides details on culturing ornamental fish at small farms, including feeding practices, water quality management, health issues, and economics.
Bacteria Busters
The document discusses the issue of antibiotic resistance caused by the introduction of antibiotics into aquatic environments through aquaculture. Approximately 50% of consumed antibiotics are directly released into water systems, as antibiotics are routinely added to fish farms to prevent disease and promote growth. This leads to antibiotic residues in farmed fish and the spread of antibiotics through the local environment. Many of the antibiotics used in aquaculture are also important for human medicine. While stopping antibiotic use and increased regulation could help, antibiotic resistance genes still spread through water. Therefore, innovative water treatment is needed to remove antibiotics, such as using Moringa oleifera seeds, which contain proteins that naturally bind antibiotics and can be filtered out. A prototype device using cyclone filtration powered by
The Nitrogen Cycle
The nitrogen cycle describes how nitrogen is converted between its various forms and incorporated into living things. Nitrogen makes up 78.9% of the atmosphere but cannot be directly used by plants and animals. It must be converted to nitrogenous compounds through processes like nitrogen fixation, ammonification, nitrification, and denitrification. Legumes have root nodules containing rhizobia bacteria that convert nitrogen to ammonia. Ammonia is further converted to nitrates and nitrites by nitrifying bacteria. Plants take up nitrates to make proteins, which are consumed by animals. Dead plants and animal waste release ammonia, continuing the nitrogen cycle.
1.3 useful microorganism
Microorganisms play an important role in decaying dead organisms and enriching the soil. They break down complex compounds into simpler ones that plants can use. Herbivores rely on bacteria in their stomach to digest cellulose from plants. Certain bacteria also live in human intestines and help with digestion while destroying harmful microbes. Some microbes like Penicillium molds produce important antibiotics that can treat diseases. Genetically engineered bacteria can produce vaccines and insulin. Microbes are crucial in agriculture by releasing nitrogen that plants need and in various industries through fermentation processes.
Water chemistry
This document discusses the importance of water chemistry in aquaponic systems. It explains that the three main biological components of aquaponic systems - fish, plants, and bacteria - are all dependent on the water being in suitable chemical conditions for their health and survival. Fish rely on water flowing over their gills to breathe and expel waste, while plants uptake nutrients and bacteria perform critical chemical processes, so all three are impacted by factors like pH, oxygen, nitrates, and other water chemistry parameters. The document emphasizes that understanding and managing water chemistry is essential for optimizing aquaponic system function and production.
Autotroph & heterotroph bacteria
The document discusses two types of bacteria: autotroph and heterotroph bacteria. Autotroph bacteria can produce organic compounds from inorganic molecules using light or chemical energy. They include photoautotrophs, which use light energy, and chemoautotrophs, which use chemical energy. Heterotroph bacteria require organic substrates for energy and are divided into parasites, saprophytes, pathogens, and non-pathogens. Common examples of different bacteria types are provided.

Problems & Profit With Waste
Sewage contains organic waste that provides food for bacteria. The bacteria multiply and consume oxygen in the water, causing other aquatic organisms to suffocate due to lack of oxygen. Sewage treatment uses microbes to convert harmful materials in sewage into harmless products through processes like activated sludge digestion and anaerobic sedimentation, allowing the treated waste to be safely released into rivers.

This document discusses the life cycle of abalone from egg to adult. It begins as an egg that is fertilized by sperm to become a trochophore larva within 24 hours. The trochophore then develops into a veliger larva within 48 hours. The veliger settles and becomes a post-larval spat within 14-21 days. The spat then grows into a juvenile within 1-3 months and finally an adult within 2-4 years, growing about 1 inch per year for the first few years. Abalone spawn between June and November in the ocean. Veligers and trochophores eat plankton while in their planktonic stage.

- Aquaponics combines aquaculture and hydroponics in an integrated system to grow fish and plants together in a closed, soilless system. It uses 90% less water and allows for year-round production of food.
- The key components of an aquaponic system include a fish tank, grow beds for plants, mechanical and biological filtration, aeration, pumps, and proper water chemistry to support the nitrogen cycle between fish waste and plant nutrients. When balanced correctly,
Wsb classroom presentation ichthyology and fish disease
Nancy Caruso is a marine biologist who studies ichthyology, the branch of zoology focused on fish classification and diseases. She discusses how fish are classified into categories like kingdom, phylum, class, order, family, genus and species. The two main types of fish are bony fish like osteichthyes and cartilaginous fish like chondrichthyes. She also outlines common fish diseases caused by bacteria, fungi, protists and parasites. Poor water quality from issues such as high ammonia, nitrites and nitrates or low oxygen can make fish sick. The best ways to prevent fish disease are cleaning the tank, identifying the cause of illness, and treating sick fish with medication.

Ecosystems consist of organisms that depend on each other. The document discusses how organisms within an ecosystem are interdependent and provides desert ecosystems as an example to illustrate this concept. Different types of ecosystems are mentioned such as ponds, rainforests, deserts, coral reefs, and swamps.
Lesson 21 worm
The document discusses worms and their role in aquaponic systems. It explains that worms like to live underground where it is dark and wet. Worms mix up the media in the system, helping plants get the nutrients they need. Worms eat decomposing roots and make compost fertilizer that nourishes the plants and promotes their health.
Lesson 18 aquaculture
This document discusses different methods for farming fish for food, including open pen fishing which contains fish in nets off shore, recirculating aquaculture systems which raises fish in tanks on land, and aquaponics which farms fish and plants together so the plants use the fish waste. It notes the concern that we want to eat more fish than what is available in the oceans.
Lesson 15 fish life cycle
A fish goes through several stages in its life cycle: it begins as an egg, then develops into a larval fish while still relying on a yolk sac for nutrients, progresses to a fry that can feed independently, becomes a juvenile fish that is not yet able to reproduce, and finally reaches adulthood where it can reproduce.
Lesson 14 parts of fish power point
The document discusses the key parts of a fish including fins, scales, gills, dorsal, caudal, rostral and ventral areas. It explores what these parts are and their functions, while also considering if humans could live like fish and breathe underwater like they do using gills. The document examines fish anatomy and physiology at a high level overview.
Lesson 10 seeds
Seeds contain a baby plant and food to nourish it. They have a protective casing to keep the embryo safe until it can grow. Seeds come in different sizes and shapes, and can travel long distances to spread plants using methods like water, animals, or other forces of nature. Their purpose is to produce new plants that will continue the life cycle.
Lesson 9 parts of plants
The document discusses the main parts of plants and their functions. It explains that roots take up water and nutrients and anchor the plant, stems transport water and nutrients and support the plant upright, leaves capture sunlight to produce food through photosynthesis, flowers contain eggs and pollen for reproduction, seeds contain the new plant, and fruit forms around and protects the seeds.
Lesson 8 p h & plants
This document discusses pH and its importance for plants. pH is a measure of how acidic or basic a substance is, and it is important because plants can only absorb nutrients when the pH is at certain levels. The document recommends maintaining a pH between 6.0 to 6.5 for optimal nutrient absorption and plant growth.
