    A5 By-catch Species APPENDIX 5: BY-CATCH SPECIES A.5 By-catch species By-catch is the unintentional/incidental capture of non-target species during fishing operations. Different types of fisheries have different types and levels of by-catch, depending on the gear used, the time, area and depth fished, etc. Article IV of the Convention states: "the Commission shall be responsible for the study of the population of tuna and tuna-like fishes (the Scombriformes with the exception of Trichiuridae and Gempylidae and the genus Scomber) and such other species of fishes exploited in tuna fishing in the Convention area as are not under investigation by another international fishery organization". The following is a list of by-catch species recorded as being ever caught by any major tuna fishery in the Atlantic/Mediterranean. Note that the lists are qualitative and are not indicative of quantity or mortality. Thus, the presence of a species in the lists does not imply that it is caught in significant quantities, or that individuals that are caught necessarily die.

  • The Serra Spanish Mackerel Fishery (Scomberomorus Brasiliensis
    ISSN 1519-6984 (Print) ISSN 1678-4375 (Online) THE INTERNATIONAL JOURNAL ON NEOTROPICAL BIOLOGY THE INTERNATIONAL JOURNAL ON GLOBAL BIODIVERSITY AND ENVIRONMENT Original Article The Serra Spanish mackerel fishery (Scomberomorus brasiliensis – Teleostei) in Southern Brazil: the growing landings of a high trophic level resource A pesca da cavala, Scomberomorus brasiliensis (Teleostei), no sul do Brasil: o aumento nos desembarques de um recurso de alto nível trófico P. T. C. Chavesa* and P. O. Birnfelda aUniversidade Federal do Paraná – UFPR, Zoology Department, Curitiba, Parana, Brasil Abstract In fisheries, the phenomenon known as fishing down food webs is supposed to be a consequence of overfishing, which would be reflected in a reduction in the trophic level of landings. In such scenarios, the resilience of carnivorous, top predator species is particularly affected, making these resources the first to be depleted. The Serra Spanish mackerel, Scomberomorus brasiliensis, exemplifies a predator resource historically targeted by artisanal fisheries on the Brazilian coast. The present work analyzes landings in three periods within a 50-year timescale on the Parana coast, Southern Brazil, aiming to evaluate whether historical production has supposedly declined. Simultaneously, the diet was analyzed to confirm carnivorous habits and evaluate the trophic level in this region. Surprisingly, the results show that from the 1970’s to 2019 Serra Spanish mackerel production grew relatively to other resources, as well as in individual values. The trophic level was calculated as 4.238, similar to other Scomberomorus species, consisting of a case where landings increase over time, despite the high trophic level and large body size of the resource.

  • SMALL TUNAS SMT-1. Generalities the Species Under The
    2019 SCRS REPORT 9.12 SMT – SMALL TUNAS SMT-1. Generalities The species under the Small Tunas Species Group include the following tuna and tuna-like species: – BLF Blackfin tuna (Thunnus atlanticus) – BLT Bullet tuna (Auxis rochei) – BON Atlantic bonito (Sarda sarda) – BOP Plain bonito (Orcynopsis unicolor) – BRS Serra Spanish mackerel (Scomberomorus brasiliensis) – CER Cero (Scomberomorus regalis) – FRI Frigate tuna (Auxis thazard) – KGM King mackerel (Scomberomorus cavalla) – LTA Little tunny (Euthynnus alletteratus) – MAW West African Spanish mackerel (Scomberomorus tritor) – SSM Atlantic Spanish mackerel (Scomberomorus maculatus) – WAH Wahoo (Acanthocybium solandri) – DOL Dolphinfish (Coryphaena hippurus) Knowledge on the biology and fishery of small tunas is very fragmented. Furthermore, the quality of the knowledge varies according to the species concerned. This is due in large part to the fact that these species are often perceived to have little economic importance compared to other tunas and tuna-like species, and owing to the difficulties in conducting sampling of the landings from artisanal fisheries, which constitute a high proportion of the fisheries exploiting small tuna resources. The large industrial fleets often discard small tuna catches at sea or sell them on local markets mixed with other by-catches, especially in Africa. The amount caught is rarely reported in logbooks; however observer programs from purse seine fleets have recently provided estimates of catches of small tunas. Small tuna species can reach high levels of catches and values in some years and have a very high relevance from a social and economic point of view, because they are important for many coastal communities in all areas and a main source of food.

Ovarian development and spawning period of S. brasiliensis were investigated using both macroscopic and histological techniques. Mean monthly values of GSI and ovarian maturation indicate that the main spawning period occurs during the rainy season. Keywords: Serra Spanish mackerel, spawning period, ovarian development, histology, GSI.

Desenvolvimento ovariano e época de desova de S. brasiliensis foram investigados utilizando-se técnicas macroscópicas e histológicas. Valores mensais médios de IGS e maturação gonadal indicam que a época de desova ocorre durante o período de chuva. Palavras-chave: Serra, época de desova, desenvolvimento ovariano, histologia, IGS.

  • A Proposal to Set up an ICCAT Year Research Program Or Small Tunas (SMTYP) Overview the Status of Small Tuna Stocks in the ICCAT
    A Proposal to Set Up an ICCAT Year Research Program or Small Tunas (SMTYP) Overview The status of small tuna stocks in the ICCAT Convention area is generally unknown. Nevertheless, these species have a high socio-economic relevance for a considerable number of local communities at the regional level, which depend on landings of these species for their livelihoods. Fisheries statistics and biological data which can provide a basis for assessing these resources and thus providing the Commission with the appropriate scientific advice for their sustainable exploitation are generally unavailable for these species. To deal with this issue and to achieve the objectives established by the 2008 Joint ICCAT GFCM Working Group (Anon. 2009a), it is now high time to establish an ICCAT Year Research Program for Small Tunas (SMTYP), whose main objective for the first two years will be the collection of statistics and biological data as well as the recovery of all the historical available data in the main fishing areas, with a focus on the priority species identified by the ICCAT/GFCM in 2008. This program has a wide geographical sampling coverage to include also the Caribbean Sea. January-December 2013: Priority for the collection of historical available data (statistical and biological data) in the main fishing area: • Mediterranean and Black Sea: Bullet tuna, Atlantic bonito, little tunny and plain bonito; • West Africa: Atlantic bonito, little tunny, bullet tuna, West African Spanish mackerel, frigate tuna, wahoo; • Caribbean area: Blackfin tuna, king mackerel and Serra Spanish mackerel. July 2014 An inter-sessional data preparatory meeting to analyse the collected data in the mains areas.
