The Federal Fisheries Council
decided to establish them for hubbsi hake, hoki, Patagonian toothfish and southern hake (Merluccius australis
) for next year. In no case have the recovery objectives been achieved so biologists ask to comply with the complementary measures.
The Federal Fisheries Council established through Resolution 13
the maximum catches allowed for the species hake hubbsi, southern hake, Patagonian toothfish and hoki. Although in some cases slight signs of recovery are observed, in others there are signs of decline in abundance, especially of the reproductive biomass. It should be noted that biologists warn on the need to comply with the management measures suggested for these species, including the reduction of juvenile fishing or the preservation of breeders.
In relation to the hake hubbsi species, a report was presented on the state of the northern stock that marks a recovery of the reproductive biomass in recent years, but it is noted that it is still below the biological reference limit points. According to Act 37, to meet the objective of recovery of the reproductive biomass, the catch should not exceed 42,000 tons. It does not report on the recovery scenarios proposed by INIDEP
as more appropriate depending on the possibility of achieving the objectives.
For the southern stock, the exploitation scenarios contemplated by researchers are not reported, not even those with the highest risk. It is only indicated that there was an increase in larger specimens, although the proportion is not explicitly stated. It is added that, based on the results obtained in the evaluation and with the intention of achieving 600,000 tons of reproductive biomass in the short and medium term, it was considered to establish the capture for 2020 at a figure “similar to that of the current year ”, of 290,000 tons.
From the diagnosis on the southern hake (Merluccius australis
) species, it was reported that the results evidenced a declining trend of abundance during most of the period and a slight recovery during the most recent years, detecting an increase in the number of juveniles resulting from recruitment more favorable and a decrease in fishing effort in the reproductive area.
According to the members of the Council, based on the future projection of the status of the resource and the risk analysis of meeting different management objectives, catch levels were estimated between 18,800 and 23,000 tons. Leaning by the scenario of greatest risk, a catch of 23,000 tons was set for the year 2020.
Regarding hoki, it was pointed out that the trends in the evolution of the biomass were variable until 2003 but that in recent years there were low entrance of individuals, with the exception of the annual period 2017. At the time of estimating the different scenarios of catch and associated risk, catch possibilities for 2020 between 60,000 and 181,000 tons were managed. The Council decided to establish a maximum catch of 80,000 tonnes.
In the case of the Patagonian toothfish, for which an extension of the closed area to protect breeders was previously established, it was reported that despite current regulations, a level of biomass that matches or exceeds the value set as objective has not yet been reached. And based on the biological reference limit points in terms of exploitation and proposed recovery objectives, catch values of 5,485 tons and 3,691 tons were handled, respectively. The Council decided to fix the catch by 2020 at 3,700 tonnes.
