MERLUZA COMÚN Merluccius Gayi Gayi (Guichenot, 1848)
Ficha Pesquera Noviembre - 2008 MERLUZA COMÚN Merluccius gayi gayi (Guichenot, 1848) I. ANTECEDENTES DEL RECURSO Antecedentes biológicos Familia Merlucciidae Orden Gadiformes Clase Actinopterygii Hábitat Batidemersal Alimentación Zooplancton (eufausidos), Necton (peces juveniles), Zoobentos (crustáceos decápodos). Canibalismo Tamaño máximo (cm) 80 cm LT Talla modal 2008 (cm) 35 cm LT (industrial); 35 cm LT (espinel); 37 cm LT (enmalle) Longevidad (años) 15 años Edad de reclutamiento 2-3 años Ciclo de vida El ciclo de vida de esta especie está fuertemente asociado a la columna de agua sobre el área de la plataforma y talud continental de Chile centro-sur (zona nerítica), aunque bajo circunstancias ambientales extraordinarias es posible que ciertos procesos se verifiquen en la zona oceánica aledaña. El ciclo de vida comienza con el desove, el cual se realiza durante todo el año (desovante parcial) aunque el período de mayor intensidad se verifica en invierno-primavera, y un período de desove secundario en febrero- marzo de cada año. Las principales áreas de desove están cercanas a la costa entre Papudo (32º30’ LS) y Bahía San Pedro (40º50’ LS), los huevos desovados son fecundados en el área demersal de la zona nerítica, pasando las larvas a formar parte del necton por un periodo hasta el momento no determinado, y estando sujetas a los típicos procesos de transporte y advección que ocurren a lo largo de la zona centro sur de Chile. Después de un año a un año y medio, los juveniles de merluza común se reclutan al stock, habitando en áreas cercanas a la costa. A partir de los 3 años (34 cm LT), los ejemplares se reclutan a la pesquería y a partir de los 3,5 años (35-37 cm LT) alcanzan la edad de madurez sexual al 50%, constituyéndose en parte del stock adulto, el cual esta asociado a la contracorriente subsuperficial de Chile y Perú (Corriente de Gunther). -
Redalyc.A Review of Longnose Skates Zearaja Chilensis and Dipturus Trachyderma (Rajiformes: Rajidae)

Bennett1 Abstract Longnose skates may have a high intrinsic vulnerability among fishes due to their large body size, slow growth rates and relatively low fecundity, and their exploitation as fisheries target-species places their populations under considerable pressure. These skates are found circumglobally in subtropical and temperate coastal waters. Although longnose skates have been recorded for over 150 years in South America, the ability to assess the status of these species is still compromised by critical knowledge gaps. Based on a review of 185 publications, a comparative synthesis of the biology and ecology was conducted on two commercially important elasmobranchs in South American waters, the yellownose skate Zearaja chilensis and the roughskin skate Dipturus trachyderma; in order to examine and compare their taxonomy, distribution, fisheries, feeding habitats, reproduction, growth and longevity. -

As fishmeal industrialists raided the oceans for proteins to nourish chickens, hogs, and farmed fish, the global “race for fish” was marked by the clash of humanitarian goals and business interests over whether the fish should be used to ameliorate malnutrition in the developing world or extracted and their nutrients exported as mass commodities, at greater profit, as a building block for the food chain in the global North. -

Merluccius tasmanicus sp. nov. di¡ers from all other congeneric species in the following combination of characters: upper pro¢le of the head slowly concave; lateral line slowly concave in the caudal region; body depth 4.9^5.9 times in standard length (SL); orbital diameter 6.1^7.1 times in head length, 2.1^2.2 times in snout length and 1.6^1.9 times in interorbital width; second dorsal ¢n rays, 42^43; anal ¢n rays, 42^44; lateral line scales *164. Merluccius australis is redescribed to clarify the identity of this species. Merluccius australis di¡ers from all other congeneric species in the following combination of characters: upper pro¢le of the head straight; lateral line straight in the caudal region; body depth 6.6^7.1times in SL; orbital diameter 4.5^5.4 times in head length, 1.2^1.7 times in snout length and 1.0^1.3 times in interorbital width; second dorsal ¢n rays, 40^43; anal ¢n rays, 40^43; lateral line scales, more than 155. -
Phylogenetic Prospecting for Cryptic Species of the Genus Merluccius
www.nature.com/scientificreports OPEN Phylogenetic prospecting for cryptic species of the genus Merluccius (Actinopterygii: Merlucciidae) Montse Pérez1, María Fernández‑Míguez1,2, Jesús Matallanas3, Domingo Lloris4 & Pablo Presa2* Hakes of the genus Merluccius include 11 valid species as well a number of rare morphotypes suspected to be “cryptic species”. Concatenated nucDNA ITS1‑rDNA and mtDNA cyt b sequences plus nested ITS1Nes sequences allowed to ascribe 14 specimens of nine rare morphotypes from the South Pacifc and the South Atlantic to the phylogenetic backbone of this genus. Bayesian analyses pointed to M. bilinearis and M. albidus as the oldest species of the genus and the New World cluster, respectively. The phylogenetic status of M. angustimanus from the upper Gulf of California suggests its hybrid origin between M. gayi and M. productus from about 0.25 MYA, although an ever since confnement of a subset of those species cannot be ruled out. The molecular phylodiagnostic test suggests a common origin of all rare morphotypes and the absence of cryptic hake species in the Southern Cone. The molecular background of the morphotypes distributed between the Western Pacifc South of New Zealand and the western Atlantic South of Argentina is compatible with their hybrid origin between M. gayi and both, M. australis or M. hubbsi, respectively. Te genus Merluccius comprises 11 valid species that occur on most temperate and tropical continental shelves except the Asian shores of the Pacifc Ocean1. Hakes show an anti-tropical distribution in the Atlantic Ocean and the Eastern Pacifc and a latitudinal bathymetric overlap between isotherms 7 °C and 23 °C2–4. -

Ha sido realizado por el Programa FAO de Identificación y Documentación de Especies del Servicio de Recursos Pesqueros Marinos, y supone una actualización de la sección dedicada a la familia Merlucciidae integrante del “FAO Species Catalogue. Vol. 10. Gadiform Fishes of the World (Order Gadiformes)” publicado en 1990. La familia Merlucciidae, que incluye las merluzas, tiene una gran interés pesquero y algunas de las especies que la componen han sido, y son objeto de una importante explotación industrial. Como consecuencia, se ha generado una abundante literatura sobre su biología y la dinámica de sus poblaciones. No obstante, existe un problema de identificación de las especies debido a las dificultades de encontrar caracteres fácilmente observables y poco variables que permitan una identificación rigurosa. -

Merluccius Polli and Merluccius Senegalensis) Using Catch-Msy and Length-Based Spawning Potential Ratio Models
grocentre.is/ftp Final Project 2019 ASSESSING THE NORTH-WEST AFRICAN STOCK OF BLACK HAKES (MERLUCCIUS POLLI AND MERLUCCIUS SENEGALENSIS) USING CATCH-MSY AND LENGTH-BASED SPAWNING POTENTIAL RATIO MODELS Kamarel Ba Institut Sénégalais de Recherches Agricoles (ISRA) Centre de Recherches Océanographiques de Dakar-Thiaroye (CRODT) Pôle de Recherches de Hann, BP: 2241, Dakar, Senegal [email protected] Supervisor: Dr. Pamela J. Woods Marine and Freshwater Research Institute, Iceland [email protected] ABSTRACT Shared by three countries (Morocco, Mauritania and Senegal), the black hakes (Merluccius polli and M. senegalensis) stocks are some of the most important resource exploited in northwest African waters. Since they resemble each other and are caught together in high proportions, the fisheries statistics record them as one species. The catches were high in the 1970s before sharply declining since 1980 as a result of an intense exploitation by the domestic and foreign vessels using bottom-trawls and longlines. Each of these countries has its own records about catch, efforts, CPUE and catch composition which generally led to pooled stock assessments during CECAF Working Groups. This study attempts to perform stock assessments using regional data (catches in metrics and in length composition) from FAO reports and data- limited methods such as Catch-MSY and Length-Based Spawning Potential Ratio (LBSPR) model as a preliminary work in order to compare reference points with existing literature and consolidate them for the fisheries management purpose. The objectives of this study were to (1) obtain information about life history parameters of both species from literature review, (2) estimate natural mortality rate M and M/k using data-limited methods, (3) provide recommendations based on assessments of black hakes using Catch-MSY and LBSPR models.
