Nutritional requirement of cultivable fin fish: larvae, juveniles and adults
Fish is among the healthiest foods on the planet. It is loaded with important nutrients, such as protein and vitamin D. Fish is also the world's best source of omega-3 fatty acids, which are incredibly important for human body and brain.
Manufactured feeds are an important part of modern commercial aquaculture, providing the balanced nutrition needed by farmed fish.
In the development of modern aquaculture, starting in the 1970s, fishmeal and fish oil were key components of the feeds for these species. They are combined with other ingredients such as vegetable proteins, cereal grains, vitamins and minerals and formed into feed pellets.
The global supply of fish meal and fish oil is finite and fully utilized. Alternative or nontraditional feedstuffs may differ in terms of taste, smell, texture, and color, as well as nutrient composition, from the traditional feedstuffs, which are produced largely from the natural prey of the fish being raised. Alternative feedstuffs may also contain compounds and antinutritional factors that affect digestive or sensory physiology.
Another important area of fish nutrition for the next 20 years will be larval fish nutrition. Currently, the cost and difficulty of rearing a great number of species from the first feeding to the juvenile stage are the most severe bottlenecks to the development of aquaculture production of nontraditional species.

Catfish Farming
The document provides an overview of catfish farming in the United States. It discusses that the channel catfish is the primary species farmed, with top producing states being Arkansas, Mississippi, Alabama and Louisiana. Catfish farming developed commercially in the 1960s in the southern US. Catfish are raised in ponds and fed prepared feeds containing protein, vitamins and minerals. Farming involves breeding stock, hatching eggs, and raising fry in ponds until harvesting at 1-1.5 pounds. Water quality, disease prevention and intermittent harvesting are important aspects of management and health.
Living Nutritious capsule for fish
Live food like plankton, rotifers, brine shrimp, and bloodworms provide excellent nutrition for fish and help enhance breeding efficiency and growth. They are rich in proteins, fats, vitamins, minerals, and amino acids essential for fish. Some live foods can be stored dry for later rehydration and use, making them convenient for transport. Overall, live foods act as "living nutritious capsules" that closely mimic the natural diets of fish and support their nutritional needs.
Fish Nutrition
Fish have more efficient feed conversion ratios than land animals like cows and pigs due to their biology and environment. Fish feeds are more concentrated in nutrients than feeds for land animals. A balanced nutrition mix for fish includes protein, fat, carbohydrates, vitamins, and minerals. Proper storage, water quality factors like oxygen, temperature, pH, alkalinity, hardness, ammonia, nitrite, and salinity are important for fish health. Routine water testing and monitoring of these factors is necessary in aquaculture.

This document discusses ways to reduce the ecological footprint of fish feed used in aquaculture. Currently, fish meal is a major protein source in fish feed due to its balanced nutrients. However, overfishing to meet demand for fish meal puts pressure on small pelagic fish populations. The document explores alternatives to fish meal such as terrestrial plant proteins, insects, terrestrial animal byproducts, and algae. These alternatives can help reduce the environmental impacts of aquaculture while still providing balanced nutrition to farmed fish. In conclusion, promoting omnivorous and herbivorous fish species that can eat plant-based diets, along with sustainable production of plant proteins, can help aquaculture be produced with less ecological impact.
Angel fish-Pterophyllum scalare
Pterophyllum scalare, commonly known as the angelfish, is native to rivers in South America. It is the most popular freshwater angelfish species kept in aquariums. There are many varieties that have been developed through selective breeding, with differences in coloration and patterning. Angelfish require a minimum 30 gallon aquarium with soft, acidic water and live plants.

life cycle of amphibian frog.pptx
Frogs go through four stages in their life cycle: egg, tadpole, young frog, and adult frog. As an egg, it is laid in water and hatches into a tadpole. The tadpole grows gills, a tail, and later legs while living in water. It then transforms into a young frog that can hop on land but is still small. Over 2-4 years, the frog will grow fully into an adult frog and complete the cycle by laying eggs of its own.
Reproduction in animals and life cycle of animals
This document discusses reproduction and life cycles in animals. It covers:

How we share the planet 2016
This document discusses the classification of living things. It explains that living things can be classified as either plants, animals, fungi or other organisms. It then goes into further detail about classifying animals into vertebrates and invertebrates. Vertebrates include mammals, birds, fish, reptiles and amphibians. Invertebrates are the largest group and include arthropods like insects and arachnids, molluscs like snails and octopuses, and other groups like jellyfish and worms. The document provides key characteristics about each of these classifications of living things.
Copepod life cycle
Copepods are microscopic crustaceans that are an important link in the food chain. They undergo multiple molting stages from nauplius larvae to adult, and reproduction is sexual. Common types include calanoid and cyclopoid copepods, which are found globally in aquatic environments. Copepods feed on algae and small invertebrates and are themselves an important food source for many marine organisms. Their distribution and pigmentation are affected by environmental factors like water temperature.
Bottlenose Dolphin Libby
Bottlenose dolphins mainly eat squid and fish. They hunt for food in groups, using their teeth to catch prey like 12-foot long squid. Babies get milk from their mothers. Bottlenose dolphins live all around the world, both in warm tropical waters and temperate oceans. Their main threats are fishing nets, pollution, and humans. They have physical features like a dorsal fin and fluke tail that help them swim fast. They breathe through a blowhole and can change its position when surfacing and diving. Bottlenose dolphins come in different colors and shapes, and their teeth can indicate age. They are playful mammals that sometimes play with potential prey instead of eating it.
Bottlenose Dolphin Libby
Bottlenose dolphins mainly eat squid and fish. They work together to catch prey as large as 12 feet long using their teeth. They swallow food whole without chewing. Baby bottlenose dolphins get milk from their mothers. Bottlenose dolphins live all around the world, though some prefer warmer waters. Their main threats are fishing nets, pollution, and humans. Bottlenose dolphins have body parts like fins and a blowhole that help them swim fast and breathe. They can be black, white, gray, or pink in color.

They move with ocean currents and use their tentacles to sting and capture small sea plants, fish eggs, larvae and other marine animals for food.
EDUC 653 Instructional Power Point: Biology (Fish)
The document provides information about fish for kindergarten students. It discusses the basic body parts of fish, which are fins, scales, and gills. It explains that fish live in water, whether in oceans, rivers, ponds or aquariums. It also outlines what fish eat, with ocean fish eating other fish and worms, while pet fish in tanks eat fish food provided by their owners.
Asexual Reproduction of Animals
Flatworms reproduce through a process called budding where they produce self-fertilized eggs that split upon release to grow into entirely new flatworms. Jellyfish and sea anemones first undergo sexual reproduction to produce a polyp, which then reproduces asexually through budding to create genetically identical medusas or adult jellyfish. Coral reefs are also formed through budding, allowing for large, fast-growing colonies of near-identical coral organisms.
Development 3 phyla
This narrated presentation discusses the development of 4 different species, two are deuterostomes and 2 are protostomes (one from the phyla Cnidaria, one from the phyla arthropoda, and two from the phylum chordata) development discussed is from early embryonic or egg stage to a mature adult. The presentation focuses on morphological development but also may key in on the purpose of each developmental stage. The creatures representing each of the phyla include the jellyfish, the honeybee, the elephant, and the platypus. Interestingly, Cnidaria have both sexual and asexual stages in their life cycle. The honeybee larvae have 3 different developmental paths they can take, the elephant has an extremely long gestation period, and the platypus is an egg-laying mammal. The video focuses on the uniqueness of each organisms development.
Puffer fish beep lexi and me
Puffer fish eat mostly invertebrates and algae. They are poisonous due to a toxin called tetrodotoxin and there is no known antidote. They live in tropical and subtropical oceans around the world and come in various sizes, from one inch to over two feet. Puffer fish have spines, teeth, and can inflate their bodies as a defense mechanism.
Fish Feeding Technique Notes
This document discusses different fish feeding techniques and mouth positions. It identifies 5 main feeding techniques: 1) filter feeders who suck in water and food through gill rakers, 2) scavengers who eat anything organic, 3) ambush feeders who hide and grab prey as it swims by, 4) gulp and suck feeders who create a current to suck in prey, and 5) surface feeders who feed at the water's surface. It also describes different mouth positions including terminal, sub-terminal, inferior, and superior openings related to these feeding techniques. Finally, it briefly covers some common fish diseases.
animal classification
The document summarizes the characteristics of different classes of fish. It discusses three main classes of fish: [1] Bony fish, which make up 95% of all fish and have skeletons made of bone; [2] Cartilaginous fish like sharks that have skeletons made of cartilage; and [3] Jawless fish like lampreys that do not have true jaws. The majority of fish fall under the class of bony fish.

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.
Classroom presentation day 3 reproduction hs marine bio
The document discusses abalone and their classification as gastropods.

Classroom presentation abalone general
The document discusses Nancy Caruso's green abalone restocking program and includes links to several YouTube videos about abalone farming and diving for abalone. It lists photo credits to Frank O'Donnel, Kevin Lee, and Tom Caruso and concludes with "The End".
Intro to aquaponics occ
- 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 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 23 ecosystem
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 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 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.
