Teacher’s Open Day

By Antonieta Costa, Lisbon ZOO (Portugal)

 

On the 12th of October, Lisbon ZOO launched the new educational program for schools and started the National Schools Contest “O Mar no Prato – Escolhas sustentáveis” (in English: “The sea in the dish – sustainable choices”) in the context of the Which Fish? Campaign.

This contest is in partnership with the Portuguese Education Ministry, WWF Portugal and Eco Schools Portugal. Aimed at pre-school, elementary, secondary and high school students, it aims to promote sustainable consumer choices with regard to seafood for more sustainability of the ocean.

The projects submitted for the contest should mobilize the local / international population for the conservation of the ocean, encouraging the adoption of behaviours that contribute to the sustainability of the planet.

What better way to raise awareness of a crisis than cooking together and sharing food?! A global movement for the sustainability of the earth and the ocean should involve changes in fish and seafood habits because we have the Sea in the Dish!

Marine Pollution Education

By Lina Gediminė, Lithuanian Zoological Gardens (Lithuania)

On October 6th, the Lithuanian Zoological Gardens hosted a World Animal Day event, where children were involved in an educational activity about marine pollution. In accordance with the new EAZA campaign “Which Fish?”, educators introduced visitors to the three primary components of the campaign: human sustainable consumption, sustainable animal feed and collection planning for sustainable aquatic species. While thinking about fish and other seafood that people and animals eat, it is impossible not to consider marine pollution. Marine pollution also causes the extinction of aquatic species.

Did you know that thrown-away plastic fragments into smaller and smaller pieces, but never goes away? Using a jar that pictures the marine food chain on it, educators were able to show how microscopic pieces of plastic gets into the smallest sea creatures and travels through the food chain.

By the way, plastic is not the only thing that pollutes our oceans and seas! During the educational presentation, an aquarium was used to symbolize the oceans, which were full of different types of trash. Every piece of trash had a deeper meaning of harm to marine life. For example, a small piece of netting symbolized over fishing and lost fishing equipment at the sea. A sunken toy helicopter was used as a tool to tell a story about oil spills from ships, planes or even oil dredging platforms after various accidents. Children cleaned it up, and after such a good job, they were praised and given prizes to encourage them to continue taking care of nature.

A successful story: the recovery of Atlantic bluefin tuna

By Dr. Antonio Di Natale – Secretary General at the Fondazione Acquario di Genova

There is a recent positive story in fishery management and it concerns the Atlantic bluefin tuna (Thunnus thynnus, Linnaeus, 1758). This iconic species is harvested by humans since ancient historical times and the tuna trap fishery is certainly the first human industrial activity, going back at least 2,700 years. More than one century ago, the number of tuna traps around the Mediterranean Sea and the Marmara Sea was over 200, well-distributed along the coasts. Catches are still unknown, but they are supposed to be much higher than in recent times. Besides, this long exploitation, recent sophisticated genetic analyses, carried out on bluefin tuna samples from the 2nd century B.C. till present days, are not showing any sign of genetic erosion, while they are showing a progressive adaptation to the available diets.

After the ‘60s, the industrial fishery used also the tuna purse-seiners, which were able to catch the bluefin tuna off-shore. This fishery was able to provide huge catches over a short period of time, usually from late May to mid-July. Due to the strong request on the Japanese market, particularly for the sashimi, it was decided to change the availability of fresh fish by month on the market, trying to distribute them over the year. This decision implied the development of a tuna fattening industry in the Mediterranean Sea, which was initiated at the end of the ‘90s and then further developed.

At the beginning of the “fattening era” it was very difficult to duly assess the catches, because the fish were moved directly into cages and also because there were no quotas. Therefore, in an open fishery regime, every fleet tried to get the maximum catches. This resulted very quickly in a clear overfishing due also to a mismanagement. The necessary international awareness addressed the issue.

Then, ICCAT (International Commission for the Conservation of Atlantic Tunas) adopted a “quota system”, which was enforced at the end of the ‘90s. This process allowed a complex “rebuilding plan” with several strict management measures, closed seasons by gear and innovative controls (including underwater stereo cameras). ICCAT decided also to introduce a certification for better controlling the fishing and farming activities, supported by international independent observers. Recently, the certification became fully electronic.

In about 10 years of these hard controls, the Atlantic bluefin tuna left the dangerous area, showing a clear progressive rebuilding in both stocks.

Due to the never-ending discussions about the data quality, the ICCAT decided to initiate an ambitious and vast research programme, called Atlantic-wide Research Programme for Bluefin Tuna, conventionally GBYP, which was mostly financed by the European Union but with important contributions by many States. The programme, which is still on going, was multidisciplinary and allowed to build the largest data base for a single marine species. The estimation of the marine stocks is not straightforward and requires the utilization of multiple data analysed through models which can show the trends of abundance as appears in Kobe plots 2009 compared to 2017:

Kobe plots for the spawning stock biomass (SSB) of the eastern bluefin tuna stock (Atlantic and Mediterranean) under three different recruitment scenarios, based on the result of the Virtual Population Analysis (VPA). Left model taken from EBFT assessment in 2009 (page 94) shows all the stocks in red zone whilst the right figure (EBFT assessment 2017, page 85) puts the stocks into yellow to green recovery zones.

Thanks to best management practices, and also to several years of favourable oceanographic conditions, the species is now fully recovered and, since three years, the quotas are progressively increasing again. This is clearly a successful story showing that  with common international will, a fishery can be managed in a sustainable manner, allowing also to recover a species having a wide distribution. A good example to follow for other species.
