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.
Road to sustainability
Sustainability refers to being environmentally friendly by using renewable energy resources and educating people to protect the earth together through collective action. We must shift to renewable energy sources and educate the public on sustainability to ensure a livable planet for future generations. Achieving sustainability will require global cooperation.
Relationships in ecosystems
Organisms in an ecosystem depend on one another through food chains and webs. Producers like plants generate their own food through photosynthesis. Decomposers break down dead matter. Consumers cannot produce their own food and include herbivores, carnivores, and omnivores. Food chains show the transfer of energy from producers to consumers. Multiple overlapping food chains form a food web. Predators hunt prey for food, with energy decreasing at each trophic level in the energy pyramid model.
Classroom presentation day 4 life cycle jr
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.

- Overfishing has caused the loss of at least 2,000 fish species, with 70% of fish stocks overfished and endangered of collapse. Aquaculture now provides nearly 50% of the world's fish for food.
- 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.

WSB day 2 WQ and aquaculture
This document discusses aquaculture and water quality parameters important for farming fish and shellfish. It lists several species commonly farmed, including catfish, tilapia, salmon, and shrimp. It then covers key water quality measurements like temperature, salinity, ammonia, nitrite, nitrate, pH, and alkalinity. For each parameter, it provides the ideal range and asks what actions should be taken if the measurement is outside the ideal range. The goal is to educate about maintaining optimal water chemistry for aquaculture systems.
Lesson 25 climate agriculture
The document discusses how the environment affects crops and what plants need to grow healthily. Plants require light, nutrients, water, and a stable environment to thrive. Environmental conditions like flooding, darkness, drought, wind, cold and more can stress plants and impact their growth if the environment is not consistent or fulfilling their needs.
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 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 20 bacteria
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.
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 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 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 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 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 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.
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 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.
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
