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.

Haemulon sciurus

This grunt is common in mangroves, reefs, and seagrass beds at depths to 98.5 feet (30m). Adults form small groups over coral and rocky substrates, especially near drop offs. The juveniles are abundant in shallow turtle grass (Thalassia testudinum) beds. Bluestriped grunts are known to occasionally face and push one another with open mouths. Although the purpose for this behavior is unknown, it is believe to be related to either courtship or territory defense.

Bluestriped grunts forage primarily in seagrass and mangrove habitats, feeding on crustaceans, bivalves, and various small fishes.

Spawning occurs during the months of January to April in the Caribbean Sea. Knowledge about the spawning behavior of the bluestriped grunt is limited. Juveniles settle into seagrass beds at sizes ranging from 9-17mm in length.

Barracuda

The barracuda is a large species of fish found in the warmer, coastal regions of the world’s oceans. There are more than 20 different species of barracuda that range in size from less than 50 cm to nearly 2 meters in length.

It is widely spread across the oceans but is more commonly found in the more tropical regions where there is an abundance of food. Although barracudas can be found in the deep ocean, they tend to prefer coastal habitats along continental shelves and close to coral reefs.

Due to the fact that barracudas can grow into very large sized fish, the barracuda has few natural predators in the ocean besides sharks and killer whales. Humans are also one of the barracuda’s main predators as they are hunted and eaten all around the world.

Although little is really known about the reproduction of the barracuda, female barracuda are known to spawn during the spring. The female barracuda releases her eggs into the water which are then fertilised externally. As with many fish species, once spawned, the barracuda mother has no interest in caring for her young.

 

Pseudanthias squamipinnis

The Sea goldie lives in the reef-associated, marine, depth range 0 – 55 m , usually 5 – 35 m environment.

Males are purplish-pink with a pink to orange streak from the eye to the pectoral-fin base, a red patch on the pectoral fin, and pale spots on a blue anal fin. They also have an elongate third dorsal-fin ray, and elongate upper and lower caudal-fin rays. Females are golden-orange with a violet streak from below the eye to the pectoral-fin base.

Like other basslets, this species is a protogynous hermaphrodite. The territorial males guard a harem of up to 10 females. If the male dies or disappears, the dominant female will change sex to replace the missing male.

A protogynous hermaphrodite. Males are very territorial dominate a harem of females and juveniles. Female to male sex change is induced by the absence or removal of males from social groups, and sex-reversal occurs over a period of 2-4 weeks.

Paralichthys dentatus

Summer flounder are found in estuarine and coastal waters from Nova Scotia to Florida. They are most abundant from Cape Cod, Massachusetts to Cape Fear, North Carolina. Within Chesapeake Bay, summer flounder are largely restricted to waters south of Annapolis, but they can be found occasionally in the upper Bay. These fish inhabit coastal and estuarine waters from spring to fall and move offshore to depths of 100 to 600 feet during the winter. Their migration is presumably brought on by decreasing water temperatures and declining photoperiods in the fall.​

Summer flounder spend most of their lives on or close to the bottom, as other flatfishes do. Flounder use their flattened shape and ability to change coloration and pattern on the eyed side of their bodies to partially burrow in the sediment, lie in ambush and wait for their prey.​

Euphausia superba

Antarctic krill are one of the most abundant and successful animal species on Earth. Scientists estimate there are about 500 million tonnes of Antarctic krill in the Southern Ocean. The biomass of this one species may be the largest of any multi-cellular animal species on the planet.

With their large black eyes, krill are mostly transparent, although their shells have a bright red tinge from small pigment spots. Their digestive system is usually visible and this is often a vivid green from the pigment of microscopic plants they have eaten. Adult Antarctic krill are approximately six centimetres in length and weigh over a gram.

Female Antarctic krill lay up to 10,000 eggs at a time, sometimes several times a season.

Ctenophore

Ctenophore, byname Comb Jelly, any of the numerous marine invertebrates constituting the phylum Ctenophora.

Ctenophores are hermaphroditic; eggs and sperm (gametes) are produced in separate gonads along the meridional canals that house the comb rows.

Most ctenophores are colourless, although Beroe cucumis is pink and the Venus’s girdle (Cestum veneris) is delicate violet. The colourless species are transparent when suspended in water, except for their beautifully iridescent rows of comb plates.

Anthoathecata

Hydromedusae form the largest group of cnidarians and are generally smaller then the true jellyfish (typically only a few millimeters to centimenters at maximum size). Hydromedusae are distinquished from true jellyfish by prodcing their eggs and sperm under the bell, but on the outside of the animal, while true jellyfish produce eggs inside the gut.

Most hydromedusae are part of a life cycle that alternates between a bottom-dwelling “vegatative” colonial stage that will bud off medusae and a pelagic “reproductive” stage that releases either eggs or sperm. The fertilized eggs then attach to the bottom to complete the cycle. Some species have eliminated the benthic phase, and simply bud off new individuals or have their colonial phase within the plankton.
