About Conference

PULSUS brings in a new spin on conferences by presenting the latest scientific improvements in your field. Listen to motivating keynotes from thought leaders, or rub elbows with pioneers across the globe. Madrid is all set for an amazing event as PULSUS proudly presents the “World Congress on Recent Advances in Aquaculture Research & Fisheries” slated on June 10-11, 2019 at Dublin, Ireland. The theme of the conference is “Sustainable Aquaculture & Fishery”.

Fisheries and aquaculture is an essential resources for food, nutrition, income and employment for billions of people all over the globe. Studies State that fish accounted for about 17% of the world population’s intake of animal protein and 6.7% of all protein intake. In addition, fish provided more than 3.1 billion humans with almost 20% of their average per capita intake of animal protein. It is an important source of essential fats (e.g. long-chain omega-3 fatty acids), vitamins (D, A and B) and minerals (including calcium, iodine, zinc, iron and selenium), particularly if eaten whole. World aquaculture production of fish accounted for 44.1% of whole production (including for non-food uses) from capture fisheries and aquaculture in 2014. Coastal habitats (e.g. mangroves and marshes), geographic information systems (GIS) and remote sensing are more and more facilitating the differentiation and process of vegetation types important for establishing baselines and monitoring change.

Monocentris japonica

The pinecone fish (Monocentris japonica) is also known as the pineapple fish, knightfish, soldierfish, Japanese pineapple fish, and dick bride-groom fish Pinecone fish are classed in the Class Actinopterygii.  This class is known as ray-finned fishes because their fins are supported by sturdy spines.

  • Kingdom: Animalia
  • Phylum: Chordata
  • Class: Actinopterygii
  • Order: Beryciformes
  • Family: Monocentridae
  • Genus: Monocentris
  • Species: japonica

It is popular in tropical aquariums because of its unique appearance. Despite that popularity, the pinecone fish is known to be hard to keep. There are four species of pinecone fish: Monocentris japonica, Monocentris meozelanicus, Monocentris reedi, and Cleidopus gloriamaris. They are all members of the Family Monocentridae.

Kiwa hirsuta

Many of the yeti crab’s distinctive features — like its stark white coloring and its “hairy” body — are the creature’s adaptations to its habitat, the researchers said. K. tyleri dwells in a “thermal envelope” of just a few square meters, where the water is just the right temperature.

The crab’s tiny habitat in the East Scotia Ridge (located in the Atlantic section of the Southern Ocean, between Antarctica and South America) contains “black smokers,” which are chimneylike vents that spew dark water that can reach temperatures of about 720 degrees Fahrenheit (380 degrees Celsius). The yeti crabs live right on top of these scorching vents.

Volvox

Volvox is a freshwater algae which is found in ponds, ditches and even in shallow puddles. Volvox is nothing but a chlorophyte or a green algae which exists as a grand spherical colony. Each little algae within the colony holds two flagella, whip-like hair. The flagella act like tails and help them move through the water. It is interesting to watch the spinning movement of volvox under water. They move fast and protect themselves from the enemies (rotifers). The algae are connected to each other by thin strands of cytoplasm which help the whole colony to swim in an organized manner. Every algae has a small red eye-spot which enables the algae to detect light and helps swim towards light. Volvox belongs to the family volvocaceae, kingdom plantae and phylum chlorophyta.

Numerous flagellate cells (around 50,000 ) form a volvox colony. Volvox can be green, golden brown, red, or brown. The cells look like ‘chlamydomonas’ (a genus of green algae). A hollow sphere called ‘coenobium’, which contains an extracellular matrix made of a gelatinous ‘glycoprotein’, holds the cells. One of the amazing volvox facts is that mature volvox colonies have a front and rear end. You may call them ‘north and south pole’, since volvox resembles a planet. The eye-spots are prominent in the northern region. This makes volvox quite unique.

Volvox grow in deeper ponds, lagoons and ditches, which receive an abundance of rainwater. In 1700, Antonie van Leeuwenhoek, a Dutch tradesman, known as the ‘father of microbiology’, discovered and described ‘volvox’.

Pangasius bocourti

Basa (Pangasius bocourti) is a species of catfish in the family Pangasiidae. Basa are native to the Mekong and Chao Phraya basins in Indochina. These fish are important food fish with an international market.

The body of the basa is stout and heavy. The rounded head is broader than it is long, with the blunt snout having a white band on its muzzle. This species grows to a maximum length of 120 centimetres (47 in). Basa fish feed on plants. They spawn at the onset of flood season and the young are first seen in June, averaging about 5 centimetres (2.0 in) by mid-June.

Brine Shrimp

At a maximum length of just over 1 cm (0.4 inch), brine shrimp are the largest animals that live in Great Salt Lake. Despite their small size, they are an important part of the lake’s ecosystem. Each year millions of birds fatten up on brine shrimp as they prepare nest or migrate around the globe. These little creatures are also important for the local economy. The brine shrimp fishing industry brings in 70 to 100 million dollars annually. Brine shrimp cysts are sold around the world as food for fish and shellfish that are raised for human consumption.

Brine shrimp are flexible in that they are able to cope with an ever changing environment, survive harsh conditions, and live on a variety of food sources.

The food that keeps brine shrimp healthiest is the microscopic algae Dunaliella veridis. Dunaliella are soft and nutritious, and they are usually plentiful early in the spring when brine shrimp hatch. But brine shrimp eat lots of other things too. They are passive filter feeders, which means they collect whatever is in the water and sweep it into their mouths. They take in anything and everything they can swallow, including cyanobacteria, archaea, bits of detritus and diatoms.

The salinity of the lake water affects the types of microbes that are available for brine shrimp to eat. Schools of brine shrimp can be found in areas with lots of high quality food.

 

Phyto-Plankton in Food web

Phytoplankton are the foundation of the aquatic food web, the primary producers, feeding everything from microscopic, animal-like zooplankton to multi-ton whales. Small fish and invertebrates also graze on the plant-like organisms, and then those smaller animals are eaten by bigger ones.

Phytoplankton can also be the harbingers of death or disease. Certain species of phytoplankton produce powerful biotoxins, making them responsible for so-called “red tides,” or harmful algal blooms. These toxic blooms can kill marine life and people who eat contaminated seafood. Phytoplankton cause mass mortality in other ways. In the aftermath of a massive bloom, dead phytoplankton sink to the ocean or lake floor. The bacteria that decompose the phytoplankton deplete the oxygen in the water, suffocating animal life; the result is a dead zone.

Red sea urchins – Strongylocentrotus franciscanus

Strongylocentrotus franciscanus, red creature which belongs to marine invertebrate group is made up of 10 fused plates with holes through which tubed feet is extended. Red Sea Urchins feed on the Seaweeds and kelp through which it plays an important role on bio-degradation. They depend on their long spines to deter predators.

Marine EchinodermsMost of them where with the poisonous spines which can harm the humans. Harmless sea urchins which appears in green and violet colour were found mostly in cooler waters. Poisonous variety is common in South Florida. The life span were approximately over 100 years. Sea urchins respond to light through the light sensitive cells present in their spines.
