Oceanic Aquaculture will team up with URI Hatchery expert to produce full Sustainable Tuna

Our ultimate goal is to achieve full sustainable product raised from eggs in hatchery, with minimum or no capture of wildstock. Professor Terry Bradley at University of Rhode Island (URI) is now focusing on closing the life cycle of Yellowfin tuna and will team up with Oceanic Aquaculture, using our Baja site to collect Tuna eggs and multiply the chances of success.

So much fish is raised “egg to plate” today — including salmon, shrimp, tilapia and catfish — that nearly half of the seafood consumed by Americans comes from aquaculture.

CONSIDERING MILKFISH AQUACULTURE AS SUSTAINABLE SOURCE OF TUNA FEED

One of the main concerns in Tuna mariculture in general is the constant need of wild sardines that is used to feed the fish to grow them to market size. In an effort to reduce immediately the pressure on the Sardine wildstock , Oceanic aquaculture is targeting different alternative feeds, including a by-product of shrimps:

There is a good supply of shrimps due to the number of shrimp vessels operating in the site’s area . These boats are often getting rid of the shrimp’s heads, throwing them back at sea. Capitalizing

CLOSED LIFE CYCLE TUNA GETTING CLOSER

Targeting full closed life cycle yellowfin Tuna through a hatchery process, OCEANIC AQUACULTURE recently made a trip to the IATTC’s Achotines Laboratories in Panama, in collaboration with the University of Miami and IATTC researchers in July 2014.

Yellowfin tuna are being reared at Achotines by Kinki University researchers working in collaboration with IATTC scientists.  IATTC is the owner and operator of the Achotines Laboratory, where for the past 18-years they have been pioneering research programs with yellowfin, including routine rearing of early-juvenile yellowfin of a similar size to those which we photographed on the

360 VIEW OF SANTA MARIA BAY FROM OUR SITE

Santa Maria Bay is part of an island chain off the coast of Magdalena bay. Each year, between May and January, Yellowfin tuna   make their way to this specific location just outside the bay, seeking ideal water temperatures and abundance of baits.

This area is well known by anglers and commercial fisheries for being one of the most prolific fishing ground in the Eastern Pacific. Oceanic Aquaculture is capitalizing on this unique location to raise its fish in their natural habitat.

Testing Transfer and Feeding of Yellowfin Tuna in Santa Maria Bay

During R&D, we stocked our 15 m pen with 20 tuna in order to test the feeding behaviour of the fish at our site.  A percentage of fish did not survive transport due to stress while in the bait hole aboard the boat, but the survivers remained healthy and began to feed within 3 days of placement in our R &D cage . These fish remained in the cage for a month, before being harvested,  feeding on a diet of shrimp heads (which are usually thrown back at sea by

Ban on Pacific Bluefin Tuna Possibe

Increased pressure from consumers and governmental agencies results in possible ban on Pacific Bluefin tuna fishing as the population dips to an all time low.

The fisheries division of the National Oceanic and Atmospheric Administration announced that it’s considering a ban on recreational and commercial fishing of Pacific bluefin tuna. After years of large-scale fishing and rising demand in the sushi industry it is estimated that as few as 40,000 adult Pacific bluefin tuna remain in the wild, around four percent of the fish’s historic average.

With catches dropping dramatically recently

“Se utilizarían 15 hectáreas para instalar jaulas flotantes de alimentación con un diámetro de 42 metros y una profundidad de hasta 20 metros; 63 hectáreas son para amortiguamiento, navegación y protección.

El cultivo de la especie, en concreto, es de atún aleta amarilla (Thunnus albacares) y jurel (Seriola SP) en la zona sureste de la bahía de La Paz.”

Demand for “pole and line Tuna” expected to double in the US

Skipjack_Fishery_MSC_CertificationAccording to the international pole and line foundation global demands for lift poled Tuna will double to triple within 5 years. This is due to the sustainability of the capture method eliminating bycatch.

 

 

“Predicted demand in Australia and New Zealand will quadruple by 2020 and demand in the US will double (see below). Several US retailers, including Whole Foods, have recently launched pole and line products.”

Completely farm-raising bluefin in Japan

A dream has come true of completely farm-raising bluefin tuna to aid sustainability of marine stocks worldwide
From the development of fish farming technologies of commercially important fish to practical models of industry-supporting research and completely farm-raising bluefin tuna, the Fisheries Laboratory aims at attaining the world’s highest level of research and education.

Completed-cycle culture to replenish depleted fish stocks

The bluefin tuna is the most prized of the tuna family. It is a large fish that grows to 3 m in length and 500 kg in weight as an adult. As the
