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.

Food and feeding habits of larvae of finfishes ppt
This document discusses the feeding habits and nutritional requirements of fish at different life stages. It begins by explaining that fish require energy, amino acids, fatty acids, vitamins, and minerals to sustain life and promote growth. It then discusses the feeding behaviors and nutritional needs of fish larvae, including their underdeveloped digestive systems and reliance on plankton and zooplankton. The document also categorizes different types of food sources for fish and classifies fish based on their dependence on food types and positions in the water column. Specific examples are provided of the feeding behaviors of fish larvae, juveniles, and adults.
Copepod
Copepods are a group of small crustaceans found in both marine and freshwater habitats around the world. They have adapted to live in the water column, on the ocean floor, and even in terrestrial wet places. Copepods use their antennae and appendages like paddles to move in either a jerky or smooth motion. They have complex life cycles where they progress through different developmental stages that may live at different depths. Copepods play an important role in ocean food webs, eating phytoplankton and being eaten by larger organisms. They have a variety of sensory abilities and can detect predators or prey using arrays of mechanoreceptors on their bodies. Copepods have
Culture of pearl oyster
Pearls are formed by pearl oysters in response to irritants in their mantle. In 1893, Mikimoto created the first cultured pearl by manually introducing an irritant into an oyster. The optimal conditions for pearl culture include water temperatures between 20-25°C, a salinity above 30 ppt, gravelly bottoms, and moderate water currents. Common pearl oyster species farmed include Pinctada maxima, P. margaritifera, and P. fucata. Major pearl producing countries are Japan, China, Vietnam, Australia, and Indonesia. The global cultured pearl trade is worth over $3 billion annually, with China as the largest freshwater pearl producer
Food and feeding habit of shellfishes
This document discusses the food and feeding habits of various shellfish species. It begins by defining shellfish and dividing them into two phyla - Arthropoda and Mollusca. For each major shellfish type (crustaceans, bivalves, gastropods, cephalopods), the document provides examples of species and describes their classification, distribution, habitat, and food/feeding behaviors. Specific species covered include crabs, shrimp, lobsters, clams, mussels, oysters, and pearl oysters. The document emphasizes that most shellfish are filter feeders that consume plankton, algae, plants, and small aquatic organisms.
Mud crab
The document provides information about the mud crab (Scylla serrata), including its classification, distribution, ecology, and methods for farming and hatchery management. It notes that mud crabs are found naturally in the Indo-Pacific region and are an economically important species. Mud crab farming can be done using grow-out systems, where young crabs are raised for 5-6 months until market size, or fattening systems, where soft-shelled crabs are raised for a shorter period. Hatchery management involves broodstock selection and care, spawning and larval rearing techniques, and achieving survival rates as high as 18.1% compared to the world average of 3-3.5
Coral reef ecosystems
Coral reefs are highly biodiverse ecosystems home to many interdependent species. Corals are composed of calcium carbonate secreted by coral polyps in a symbiotic relationship with algae. This relationship provides nutrients to the polyps and gives corals their color. There are two main types of corals - hard corals with rigid skeletons and soft corals without. Coral reefs consist not just of corals but also many other plants and animals that rely on corals for food and shelter. The ecosystem derives its initial energy from sunlight which powers photosynthesis, providing energy that passes through the food web.
Oyster and mussel culture techniques
This document provides information on oyster and mussel culture techniques. It discusses the importance of shellfish aquaculture for food production and livelihoods. Oyster culture techniques are described in detail, including the biology and life cycle of oysters, breeding habits, larval development, setting behaviors, and environmental factors like food sources, predators, and fouling organisms that affect oyster farms. The objective is to understand different culture methods for farming oysters and mussels commercially.
fish predation
Marine fish employ a variety of behavioral and morphological adaptations to avoid predation. Behaviorally, fish school together for safety in numbers, migrate to safer habitats, and care for offspring. Morphologically, fish have body shapes and colors that camouflage them, strong fins and scales for defense, senses like lateral lines to detect predators, and some can even shock or fly away from threats. Both behavioral and physical adaptations are crucial for the survival of prey fish and maintenance of ecosystem balance.

B2 higher revision
There are five kingdoms that classify organisms based on their cellular structure: Animals, Plants, Fungi, Prokaryotes, and Protoctists. All organisms can also be classified in a hierarchical manner from the broadest category of kingdom down to the specific species level. The binomial system of scientific naming developed by Carl Linnaeus assigns every species a two-part scientific name. Modern classification is based on evolutionary relationships determined by comparing DNA sequences and other genetic evidence.

Dinoflagellates are mainly marine plankton that can cause red tides that kill fish. Chrysophytes were once thought to be cyanobacteria but fossil evidence shows they evolved separately.
Bae 495r Stream Ecology
Streams are ecosystems that provide the basic requirements for life including water, nutrients, energy, and an electron acceptor like oxygen. Organisms living in streams must find ways to obtain these necessities in the flowing water environment. The riffle habitat within streams provides advantages for both autotrophs and heterotrophs due to higher oxygen, light levels, and habitat structure compared to pools. Woody debris and other obstacles are important for creating microhabitats and retaining organic matter that fuels the food web.

This document discusses reef-building corals. It explains that corals are colonial organisms composed of polyps that capture food using stinging cells called nematocysts. Most reef-building corals have a symbiotic relationship with algae called zooxanthellae, which provide nutrients to the coral in exchange for shelter. Over many years, stony coral polyps can create massive reef structures by secreting calcium carbonate skeletons. Corals can reproduce both asexually by budding and sexually by mass spawning events, where corals release eggs and sperm that develop into planktonic larvae.

This document summarizes key aspects of zooplankton. It discusses that zooplankton include protozoa and other protists, rotifers, cladocerans, and copepods. It describes their feeding behaviors, life cycles, and vertical distributions within bodies of water. Specifically, it notes that protists are important microbial consumers, rotifers feed via ciliary movements, cladocerans filter feed using leg setae, and copepods include herbivorous and carnivorous species.
Porifera by Amit Rulhania
There is some slides which tells about the general characters and classification of phylum porifera.
Eco Tank
The document summarizes background information on various organisms and substances that could be included in an experimental eco-tank, including their biological classifications and relevant characteristics. It discusses fish (platy fish), shrimp, snails, algae, and aquatic plants (Elodea, Vallisneria). For each, it covers anatomy, diet, life cycle, predators, and environmental tolerances. The goal is to investigate the interactions between organisms and how substances affect the environment within the controlled eco-tank.
MOLLUSKS
NATURE IS FULL OF BLOSSOM AND BEAUTY AND IT ATTRACTS EVERY ONE WHO WANNA DIVE INTO IT, ONE OF THE FLOWERS OF NATURE ARE MOLLUSKS WHICH ARE CALLED THE BEAUTY OF THE OCEANS AND THEY ARE PRESENT IN A LARGE VARIETY.
SO, HERE IS SOME CUTE AND INTERESTING INFORMATION ABOUT MOLLUSKS FOR YOU GUYS.
ALIKE WILL BE APPRECIATED.
Life Near The Surface (Chapter 15)
The document discusses life near the surface of the ocean. It describes the epipelagic zone, which extends from the surface to 200 meters deep. This zone contains the highest abundance and diversity of organisms. Phytoplankton and zooplankton dominate as they can photosynthesize or feed on phytoplankton. Organisms in the epipelagic zone have adaptations to stay afloat such as streamlined shapes, gas-filled structures, or high lipid content. They also face predation and must find ways to eat while avoiding being eaten.
Insects of aquatic ecosystem
This document discusses aquatic insects and their importance in aquatic ecosystems. It begins by defining aquatic insects and categorizing them into four groups based on their habitat. It then describes 12 orders of aquatic insects and provides examples of insects in each order. The document outlines the lifecycles and adaptations of various aquatic insects to live in water, including respiration, reproduction, and locomotion. It discusses the roles of aquatic insects in aquatic food webs and their use as indicators of water quality. The document also covers important human health impacts from mosquitoes and the use of aquatic insects in forensic science.
Chapter 12
The document discusses the characteristics of the mollusca phylum. It notes that molluscs have soft bodies and come in a wide variety of forms, including snails, clams, and octopuses. The phylum is very successful, with over 100,000 species, and molluscs have adapted to live in many different environments through evolution. The three main classes of molluscs - gastropods, bivalves, and cephalopods - are also introduced.
Coral Reef Ecosystem - Background Information
Coral reefs are formed by coral polyps, which are small marine invertebrates related to jellyfish and anemones. Coral polyps secrete calcium carbonate to build protective structures called coralites. Over time, the accumulation of coralites forms three types of reef structures: fringing reefs near shorelines, barrier reefs separated from shorelines by lagoons, and atolls surrounding central lagoons. Coral reefs provide habitat for many species but are threatened by rising water temperatures and pollution.
