FISH AND FISHERIES OF INDIA
Introduction of Fish and Fisheries of India.
• Freshwater Fish: Fish that spend most or all of their life in freshwaters, such as rivers and lakes, having a salinity of less than 0.5 ppt. Around 40% of all known species of
fish are found in freshwater.
They may be divided into Coldwater Fish (5-20 °C); examples: Mahseer, Trout, etc., and Warmwater Fish (25 35 °C); example: Carps, Catfish, Snakeheads, Featherbacks, etc.
• Brackishwater Fish: Fish that can tolerate a wide range of salinity (0.5 30.0 ppt)
and live in backwaters, estuaries and coastal waters.
Example: Mullet, Milkfish, Seabass, Pearlspot, Mudskipper, etc.
• Marine Fish: Fish that spend most or all of their life in seawater, such as Seas and
Oceans, having salinity above 30 ppt. There are about 240 species contributing to
the marine fisheries. Example: Sardines, Mackerel, Ribbonfish, Anchovies, Grouper, Cobia, Tuna, etc.

Modern hatcheries now have precise environmental control and include features like vertical jars, plastic buckets, or entire Chinese-style hatchery systems. The role of hatcheries is crucial to reliably produce high quality fish seeds for farming.
Fish by products ; by UMAIYA FAROOQ
Fish byproducts are secondary products derived from fish processing that are used for various purposes. Approximately 1/3 of the world's fish catch is used to produce byproducts rather than direct human consumption. Major fish byproducts include fish oil, fish meal, fish silage, fish glue, fish fertilizer, tatami iwashi, isin glass, fish skin, and fish protein hydrolysates. These byproducts provide benefits such as omega-3 fatty acids from fish oil, protein for aquaculture feed from fish meal, fertilizer for agriculture from fish waste, and gelatin and collagen from fish skin processing. Fish byproducts are a valuable utilization of fish parts that would otherwise be wasted.

This document discusses the goals and objectives of fisheries management according to the FAO Code of Conduct for Responsible Fisheries. It outlines that the overarching goal is the long-term sustainable use of fisheries resources. Specifically, the goals are to maintain target species and ecosystem health while maximizing economic and social benefits like employment and food supply. Objectives aim to operationalize these goals, for example maintaining fish populations above 50% of unexploited levels. International agreements through bodies like the UN are needed to regulate fisheries that cross borders or are in international waters.
Immunostimulants role in aquaculture
Immunostimulants are being increasingly used in aquaculture as an alternative to antibiotics and chemotherapeutants to control disease outbreaks. Some commonly used immunostimulants include beta-glucans from yeast and plants, levamisole, chitin, and chitosan. These substances enhance the cellular and humoral immune response in fish by stimulating phagocytic cells, natural killer cells, complement systems, lysozyme activity and antibody responses. The document reviews the mechanisms and roles of various immunostimulants in initiating both the innate and acquired immune response in fish. It also discusses the administration and effects of different immunostimulants like beta-glucan, lev

Traditional fishing Craft of India by Ashish sahu
Fishing crafts are most essential for catching the fish in large scale in water bodies. A large variety of crafts (boats) have been designed for marine and inland fishing in India. The types of fishing crafts of India falls under two general categories. These are Non –mechanized and mechanized fishing crafts.
Based on the topographical variations and difference in habits and habitats of fishing, different types of crafts and gears are used in various inland water system of India. The simplest and most primitive types of craft used for fishing in inland water are the rafts and songas, operated in calm water. In the larger rivers and estuaries subject to strong current and tidal movement, sturdier plank boats are used.

It defines aquaculture as the cultivation of aquatic populations under controlled environments for human consumption. While aquaculture has advantages like providing food and economic benefits, it also has disadvantages such as pollution, disease risks, and negative social impacts including displacement of local farmers. The document examines case studies of aquaculture development in Japan and Bangladesh and challenges facing further expansion, such as overfishing, bycatch, and pollution.
Sushi powerpoint w embedded
Sushi has its origins in China in the 4th century as salted fish placed in cooked rice to ferment. It may not have become popular until the 9th century in Japan. Early forms of sushi involved fermenting rice and salted fish together for months. Over time, methods developed where the fermentation period was shortened to a month or just one day. In the 18th century, forms like hako-zushi and maki-zushi that did not require long fermentation were created. By the 1820s, nigiri-zushi was developed using fresh rice, vinegar, and fish on top. Sushi spread to North America in the 1970s, with California introducing rolls
Preparation of Value Added Fish Product: Fish Ball
This document provides instructions for making fish balls. It details cleaning and scaling two whole mackerels, removing the head and bones, chopping the fish flesh and adding salt. The chopped fish is then pounded into a paste and cornstarch is added. Small balls of the paste are formed and cooked when they float in boiling water. The fish balls can be frozen for later use. The conclusion notes that fish balls make use of fish that may otherwise go unused due to problems with color, flavor, size or fat content.

Bridging the gap between mobile and computer forensics
Mobile devices are becoming an increasingly integral part of criminal, legal, and regulatory investigations and disclosures.
However, computers and mobile devices are often examined separately by different people, often due to technical and procedural reasons. That can make it almost impossible to identify and review evidence and intelligence across multiple data sources, devices, and crime scenes. Only when we look at all of the devices at the same time will we start to see the complete picture.
In this webinar, we will look at some of the trends and challenges in acquiring and analysis mobile devices and will discuss:
- What we can expect to recover from mobile devices today
- What this data looks like when reviewed using Nuix
- Techniques and workflows for optimising investigations that include mobile devices, computers, and cloud-based evidence.

Effect of Cooking on the Polyunsaturated Fatty Acid and Antioxidant Propertie...
The effect of cooking method on the polyunsaturated fatty acid and antioxidant properties of small indigenous freshwater fish species, Amblypharyngodon mola and Puntius sophore of the Eastern Himalayas were determined. In the raw and fried samples, docosahexaenoic acid was significantly higher (2.907 and 1.167mg/100g) in Amblypharyngodon mola and lowest (0.749 and 0.291mg/100g) were recorded in Puntius sophore. The eicosapentaenoic acid of raw, fried and curried samples of Amblypharyngodon mola were recorded higher. In DPPH (1,1-diphenyl-2-picrylhydrazyl) free radical scavenging assay of IC50 value of the raw fish extract were 2.9μg/ml and 1.66μg/ml respectively. The highest antioxidant activity was found in fish curry of Amblypharyngodon mola (0.11μg/ml). It shows that the Maillard reaction product forms the melanoidin during cooking, increases the antioxidant property of the fish curry and also improved the taste.
Vitamins
Vitamin A has an important role in vision. It exists in multiple forms including retinol, retinal, and retinoic acid. Retinal is involved in the visual cycle which allows rhodopsin in the eye to regenerate light sensitivity. Vitamin A deficiency can cause night blindness and damage to surface tissues like the cornea. Both deficiency and toxicity of vitamin A can impact health. It is important for cell differentiation and growth.

Skin penetration and UV damage by nanoberries
This document describes a study investigating nanoberries (NB), which are ultradeformable liposomes carrying an ethanolic blueberry extract, for their ability to penetrate the skin's stratum corneum and provide protection from UV damage. The NB were characterized and found to be around 100 nm in size with low toxicity. Ex vivo skin penetration experiments showed the NB were able to penetrate the stratum corneum. In vitro tests then demonstrated that when skin cells were exposed to UV radiation in the presence of NB, their viability was maintained, indicating the NB provided protection from photodamage. The results suggest NB could be an effective topical formulation for protecting skin from environmental damage caused by sun exposure.

our paper
This document summarizes a study that investigated the effects of o-phenylenediamine (oPD) exposure on biochemical parameters in the liver and brain of zebrafish. Zebrafish were exposed to 1ppm and 5ppm of oPD for 15 days. Biological oxygen demand tests found moderate pollution in water treated with both concentrations of oPD. Exposure resulted in increased liver oxidative stress and alterations in liver detoxification enzymes and brain monoamine oxidase activity, suggesting oPD toxicity affects multiple organ systems. The study aims to understand the chronic effects and toxicity mechanism of oPD in aquatic animals like zebrafish.
piracetam and vinpocetine ameliorate rotenone induced parkinsonism in rats.
Rotenone was used to induce Parkinsonism in rats. Piracetam and vinpocetine were evaluated for their neuroprotective effects. Rats treated with rotenone showed motor impairment, loss of dopamine neurons, and increased oxidative stress. Treatment with piracetam or vinpocetine improved motor function in tests, increased dopamine levels, reduced oxidative stress markers, and protected dopamine neurons compared to rotenone treated rats based on histological analysis. The results suggest piracetam and vinpocetine have neuroprotective effects in a rotenone model of Parkinson's disease.

Protective Effect of Phyllanthus Amarus by Modulation of Endogenous Biomarker...
Aim: To evaluate the protective effect of phyllanthin and hypophyllanthin of standardized aqueous extract of Phyllanthus amarus in acetic acid induced colitis model of inflammatory bowel disease in Wistar rats.
Methods: Rats were rendered colitic by a colonic instillation of 2 ml (4%) acetic acid solution. Rats were pretreated orally for 7 days before induction of colitis with P. amarus (50, 100 and 200 mg/kg) or vehicle (1 ml of distilled water). Colonic inflammation was evaluated by disease activity index, gross morphologic damage, histological injury and different biochemical markers of colonic inflammation such as superoxide dismutase (SOD), reduced glutathione (GSH), malondialdehyde (MDA), myeloperoxidase (MPO), nitric oxide (NO) and tumor necrosis factor-a (TNF-a) were performed in colonic contents from colitic rats. DNA damage, a marker of apoptosis was also assessed in colonic contents.
Results: The results show that P. amarus (100 and 200 mg/kg) exerted a preventive anti-inflammatory, antioxidant and anti-apoptotic effect in this model of rat colitis, as evidenced by a significant increase in SOD and GSH content as well as reduction of MPO activity, by a decrease of MDA and reduction in NO as well as TNF-a production which is unregulated as a consequence of the inflammatory status. It also significantly decreased the extent of DNA fragmentation.
Conclusion: In conclusion, it is strongly suggested that the potent anti-inflammatory and anti-apoptotic effects of P. amarus in rats with acetic acid induced colitis are mediated via the neutrophil infiltration inhibition, inhibition of pro-inflammatory mediator production and reducing DNA damage due to the presence of phyllanthin and hypophyllanthin phytoconstituents which offers a promising means for the treatment of diseases characterized by inflammation of the gastrointestinal tract.
Bryophyllum Pinnatum: A Potential Attenuator of Cadmium-Induced Oxidative Str...
Cadmium has been famously implicated in the stimulation of free radical production in biosystems resulting in oxidative deterioration of lipids, proteins and DNA, and initiating various pathological conditions in humans and animals. This study therefore, examined the antidotal and ameliorative capacity of crude ethanolic extract of Bryophyllum pinnatum on cadmium-induced oxidative stress using rabbit models. A total of fifteen rabbits (1.30±0.05kg) were used for the study. After two weeks of acclimatization, the rabbits were randomly rifted into three experimental groups- (N, CD & CB) with five animals per group. The control group (N) was injected normal saline intraperitoneally (3mg/kg body weight) and the test groups (CD & CB) were administered cadmium once daily by subcutaneous injection (3mg/kg body weight). The ethanolic extract of the plant was orally administered once daily at a dose of 100mg/kg body weight. The oxidative and antioxidative stress parameters were assessed in tissues. The results showed significant difference (p˂ 0.05)in treated groups relative to the control group with the exception of glutathione peroxidase activity in leg muscles. Therefore, the results obtained in this study confirmed the potency of the plant to annihilate cadmium toxicity in animals
Irisin and I/R injury
Irisin plays a pivotal role in protecting the heart from ischemia and reperfusion injury. The study found that irisin treatment improved heart function after ischemia and significantly reduced infarct size. Irisin increased antioxidant enzymes and p38 phosphorylation while decreasing apoptosis markers. It also protected mitochondria by suppressing opening of the mitochondrial permeability transition pore and reducing mitochondrial swelling. The results indicate that irisin's cardioprotective effects are linked to improvements in mitochondrial function.

Sustainability of Aquaculture in Bangladesh
Aquaculture is an important sector for Bangladesh's economy and food production, accounting for 5% of GDP and 6% of exports. However, many existing aquaculture practices are unsustainable, as they have led to environmental degradation like destruction of mangroves and wetlands for pond construction, soil acidification, and salinization of land and water. They have also negatively impacted livelihoods by reducing access to resources for local communities. Truly sustainable aquaculture requires practices that do not significantly disrupt ecosystems, are economically viable, and contribute to social well-being. Improving feed sources, closed containment systems, native species selection, and community inclusion can help make aquaculture more environmentally friendly and equitable.
Use of Artemia in Aquaculture in Bangladesh
This document discusses the use of Artemia (brine shrimp) in aquaculture in Bangladesh. It provides background on Artemia, describing what it is, its nutritional value, and importance in aquaculture. While Artemia is widely used in fish hatcheries in Bangladesh, the country currently imports cysts due to difficulties in domestic production. However, Bangladesh has suitable conditions for culturing Artemia and prospects for future domestic production to meet local aquaculture needs.
Rice fish integrated farming
Rice and fish have long been integral to life in Bangladesh. Integrated rice-fish farming provides a solution to meeting the country's growing demand for food by producing both crops concurrently or sequentially on the same land. This increases total production, provides protein through fish consumption, and maintains soil fertility and ecological balance. Common techniques for rice-fish farming in Bangladesh include concurrent culture during the wet season or alternate culture with fish production after rice harvest when water levels are higher. Several small fish species that can survive in shallow water are well-suited to rice-fish systems.
Molecular markers application in fisheries
1. Molecular markers are powerful tools that can detect genetic variation between individuals, populations, and species. They have revolutionized research on evolution, conservation, natural resource management, and genetic improvement programs.
2. There are two main types of molecular markers - those based on DNA hybridization and those based on PCR amplification. Examples include restriction fragment length polymorphism (RFLP) and random amplified polymorphic DNA (RAPD).
3. Molecular markers have a variety of applications in fisheries, including identifying fish species, studying genetic variation and population structure in natural populations, comparing genetic variation between wild and hatchery populations, and marker-assisted selection in aquaculture.
Recent achievement of bangladesh on the right on sea
Bangladesh had longstanding maritime boundary disputes with India and Myanmar over areas in the Bay of Bengal. In recent years, Bangladesh was able to gain significant territory through international arbitration. With Myanmar, Bangladesh gained 111,000 square kilometers awarded by ITLOS, more than the original 107,000 square kilometers claimed. With India, Bangladesh gained 19,467 square kilometers of the disputed 25,602 square kilometers in the Bay of Bengal. These gains give Bangladesh sovereign rights over resources and ability to utilize the marine areas for fishing and potential oil/gas exploration.

The document is an informative reference on the key traits and cultivation needs of important carp species.
Immersion & spray freezer
This document discusses two types of freezers used in fish processing - immersion freezers and spray freezers. Immersion freezers freeze fish by submerging them in a liquid refrigerant bath, allowing for efficient heat transfer. Spray freezers spray fish with a refrigerated liquid like liquid nitrogen, rapidly freezing the surface. Both methods freeze fish quickly while preventing freeze burn. Immersion freezing risks refrigerant penetrating the fish, while spray freezing has high operating costs due to liquid nitrogen usage. The document examines the working principles, advantages, and disadvantages of each freezer type.
Ber jal
Ber jal is a large rectangular seine net used widely in Bangladesh and neighboring countries to catch large fish species like rohu, catla, chital, and boal. It requires many people to operate - one end is held on the bank while the other is spread in a semi-circle in the water, then the two ends are closed together. The net is made of synthetic twine and rope, with bamboo sticks along the top and bottom and floats and sinkers attached. Students were able to make a replica ber jal net using mosquito netting, styrofoam floats, rope, and bamboo plates to demonstrate how it works and potentially help with future fish harvesting.
Shrimp hatchery
The document discusses shrimp hatcheries, including their importance in supplying shrimp fry for farms. It describes the ideal conditions for establishing a shrimp hatchery, such as selecting a suitable site with access to clean sea water, electricity, and spawners. The document outlines different types of hatchery designs and sizes, from small backyard hatcheries producing a few million fry annually to large commercial hatcheries producing over 20 million fry. Key factors for hatchery success include site selection, design efficiency, technician experience, and operational management.

This document discusses common fish diseases, including bacterial, viral, fungal, parasitic, and nutritional diseases. It provides signs and symptoms of each disease, such as reddened fins, rapid breathing, and loss of appetite for bacterial disease. Images also show fish affected by each disease. The conclusion recommends learning disease signs and symptoms so farmers can properly treat diseases, which are harmful for wild and farmed fish and can cause heavy losses.
General sings & symptom of disease fish
The document discusses general signs and symptoms of diseases in fish. It covers bacterial, viral, fungal, parasitic, nutritional and genetic diseases. For bacterial diseases, common signs include reddened or frayed fins, open sores, and rapid breathing. Viral diseases can cause gastrointestinal issues, sneezing, and weight loss. Fungal infections present as white or gray growths on fins and skin. Parasitic diseases are signaled by inactivity, loss of appetite, and visible parasites. Nutritional deficiencies result in issues like poor growth or eye problems. Genetic diseases exhibit symptoms depending on the specific condition.
Biology of mussels & Camps
Mussels are bivalve molluscs that live in both marine and freshwater environments around the world. They have two shells that are connected by a ligament and use a muscular foot to burrow or position themselves. Freshwater mussels play an important role in ecosystems but many species are threatened by habitat loss. They have a unique lifecycle where larvae attach to fish hosts for several months before detaching and developing on the river or lake bottom. Mussels are filter feeders that draw in water and feed on plankton and detritus. Their reproductive strategy involves releasing large numbers of small eggs into the water to be fertilized, maximizing dispersal.
Gonadotropin Releasing Hormone (GnRH)
GnRH is a peptide hormone released from the hypothalamus that stimulates the release of FSH and LH from the pituitary gland. In fish, GnRH is expressed early in development as neurons migrate and form populations in the brain. GnRH mRNA and peptide have also been found in fish gonads, suggesting a potential paracrine role, though the exact role is unclear. GnRH receptors have been identified in the gonads of several fish species. GnRH has been shown to stimulate meiosis in fish oocytes and affect behaviors like territoriality in some fish. Further research is still needed to fully understand GnRH function in fish.
Genome
The genome is the total genetic material of an organism, including its genes and DNA sequences. It contains all the information needed to build and maintain an organism. The human genome contains around 3 billion DNA base pairs organized into 46 chromosomes. Studying genomes provides insight into an organism's development, traits, disease susceptibility, and evolutionary history. There are different types of genomes, including prokaryotic, eukaryotic, nuclear, mitochondrial, and chloroplast genomes. The genome sequences reveal everything about an organism's life through the coding and regulation of genes.
Setting up a aquarium
Setting up an aquarium requires careful planning and preparation. Key steps include: 1) selecting an appropriate aquarium size and stand, 2) properly setting up the aquarium by sealing it and allowing it to cure, 3) cleaning and positioning the aquarium, 4) adding an appropriate substrate and decorations like plants and rocks, 5) cycling the water by adding a source of beneficial bacteria, 6) slowly acclimating fish when the aquarium is ready, and 7) maintaining water quality with filtration and aeration. Proper setup is essential for supporting aquatic life.
Fish disease and health management
Fish disease is a major constraint to aquaculture development in Bangladesh. Common diseases include bacterial, fungal, parasitic and physical ailments. The risk of disease outbreaks increases with intensification of aquaculture and high stocking densities. Proper management practices like monitoring health, controlling transboundary movements, training workers and utilizing disease prevention techniques can help control disease spread and its impacts on aquaculture.
Fish ball
1. This document provides a traditional recipe for Chinese fish balls made from mackerel or other white fish.
2. The fish is cleaned, filleted, and chopped finely along with salt, white pepper, and cornstarch to form a paste.
3. The paste is repeatedly pounded and kneaded to create a smooth, springy texture before shaping into balls and freezing for later use.
Factors influencing distribution of nutrition elements in sea
- The document discusses factors that influence the distribution of nutrients in the ocean, specifically carbon, nitrogen, and phosphorus.
- Photosynthetic phytoplankton near the surface produce organic matter using nutrients from the water. After dying, this organic matter either decomposes and returns nutrients to the water or sinks deeper.
- Nutrients are depleted at the surface but enriched deeper where organic matter decomposes. Upwelling currents return nutrients to the surface, fueling new growth.
- The ratios of phosphorus, nitrogen and oxygen in seawater closely match what phytoplankton need, though the reasons for this are still debated. Organic processes may help control nutrient ratios available for life.
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. They are generally peaceful community fish but may become territorial, especially pairs breeding or guarding fry.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like

Medical applications of fisheries byproducts
- 1. Submitted by: Nazmul Ahmed Oli Reg: 12-05-2835 Level: IV Course code: FIT-401 Medical Applications of Fisheries Byproducts
- 2. Introduction: A by-product is a secondary product derived from a manufacturing process or chemical reaction. Fisheries by-products like fish meal, fish oil, fish chitin, fish protein concentrate, fish silage, prawn shell and head extracts.
- 3. Objectives The purpose is to show the potential benefits of utilizing phospholipids, glycogen, peptide glycan, chitin and DNA contained in the by-products and wastes and use in the medical purpose.
- 4. The Sn-2 Docosahexaenoic Acid Inserted Phospholipids: The sn-2 DRA inserted phospholipids (sn-2 DRA- PL) have many functional benefits For example, the sn-2 DRA-PL is known to enhance survivals of tumor bearing mouse and to promote cell differentiation of erythroleukemia cancer cells.
- 5. Figure 1: Antitumor effect of sn-2-DHA-PC/PS. The sn-2 DRA-PL liposomes with 70% phosphatidylcholine (PC) and 30% phosphatidylserine decreases tumor size of the Meth-A fibro sarcoma bearing mice without any immunomodulator encapsulated
- 6. Figure 2: Cytotoxic effect of sn-2 DHA-PC/PS liposomes on Meth-A fibrosarcoma.
- 7. Squid Pen-Chitin Laminated With Salmon Skin Collagen As An Artificial Human Skin Squid pen-chitin is much softer even though strength against tearing For this reason, squid pen-chitin laminated with salmon skin collagen must be a favorable (19 artificial human skin.
- 8. Salmon Testis DNA-Alginic Acid Film Kitamura and his co-workers developed a salmon testis DNA-alginic acid film to impregnate silver ion. This was successfully done merely by mixing up silver nitrate before casting.
- 9. Novel Antitumor Peptidoglycan Matsue et al. discovered that squid ink from Illex argentinus has an antitumor activity. They found that a novel peptidoglycan with fucose was the one that exerts the antitumor activity through modifying the biological response of the phagocytic activity of macrophages.
- 10. Conclusion: It has a great potential to discover the new medicine or new medical product from fisheries by products or wastages. So proper research field should be developed in this field.
