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 August 20-21, 2018 at Rome,Italy. 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.

Salmon

Most salmon farms hold more than one-half million fish penned in open net-cages, mostly Atlantic salmon. There are over 100 open net-cage farms growing farmed salmon in sheltered bays along the British Columbia coast.

Waste, chemicals, disease, and parasites from the farms pass through the mesh and pollute the surrounding water and seabed. Especially harmful are the sea lice who attach to wild juvenile salmon on their migration out to sea. Too many sea lice can kill the young wild salmon.

Storms, accidents and predators can tear the nets allowing the farmed fish to escape. Predators like seals and sea lions are often shot. Many marine mammals get entangled in the nets and drown.

King (chinook): The lushest fresh salmon, king is the highest in fat and usually the most expensive, prized for its silken, melting texture, which is almost like smoked salmon.

Sockeye (red): With a deep, natural color, sockeye is lower in fat but still high overall, allowing the flavor to better come through. Many salmon lovers, including me, consider this the best salmon-eating experience.

Coho (silver): A comer, according to Bill Webber and Thea Thomas, independent Cordovan fishermen. It’s already prized by sport fishermen for its fight, and soon, the Cordovans hope, by diners for its mild but distinctive flavor. The most widely available autumn fresh salmon.

Pink (humpback): So delicate and pale that Thomas compares it to sole—which she does not mean as a compliment. She recalls a tasting for food writers at which many rated pink the highest. “How could they?” she asks. The likely answer: “A lot of these people had never had salmon in their life.”

Pink Salmon

Chum (dog): Like pink, chum is fished in high numbers and is lower in fat than other varieties; when it spawns in intertidal waters, it doesn’t need to build up energy to swim upstream. Its roe, however, is the most valued of the five varieties, because of its size and flavor. After being strained and separated, the eggs make particularly good ikura— the fat, bright-orange pearls familiar in sushi rolls.

Order:         Arguloida

Family:       Argulidae

Genus:        Argulus

Species:      Argulus foliaceus

 

the common fish louse, lives in marine, brackish, and freshwater environments. usually a fish, via its suction cups, pierces the skin with its sharp stylet, and feeds on blood. A heavy infestation causes inflammation of the skin, open hemorrhaging wounds, increased production of mucus, loss of scales, and corrosion of the fins. The fish can become anemic. The damage and infection cause stress and mortality.

 

Argulus is very flat with an oval or rounded carapace, two compound eyes, sucking mouthparts with a piercing stylet, and two suction cups it uses to attach to its host. Its paired appendages have hooks and spines and are used for swimming.

 

Flavobacterium columnare in Tilapia

Columnaris disease was first reported by Davis in 1922. This is also called as saddleback disease, cotton-wool disease, cotton-mouth disease, and fin rot. Tilapia is native to Africa and the Middle East. Tilapia immune responses and the rates of pathogen replication are usually correlated with water temperature. Generally, infected fish will show signs of bleeding or have wounds along its body. Flavobacterium columnare are long, thin, gram-negative, aerobic, microaerophilic, or anaerobic gliding rod
