The use of the common name hake for this diverse group of fish prompts questions such as: how are these species related and how can they be differentiated? Chapter one details the development of the Rapid Gadoid Identification Assay (RaGIA) for molecular identification of 11 gadoid fishes (including six hakes) using Polymerase Chain Reaction Restriction Fragment Length Polymorphism (PCR-RFLP). RaGIA was used for species identification of fillets of hake, pollock and haddock sold in southern Maine markets. Testing found that market labelling was accurate; however, there were inconsistences in the labels provided by the fish distributors (from whom the markets obtained their fillets). Chapter two explores the development of a phylogeny, based on a mitochondrial DNA gene and a nuclear encoded gene, which includes members of the families Gadidae and Merlucciidae. The resulting phylogeny was used for morphological character mapping and investigation of trait evolution in this group. Consistent with previous studies, the analysis resolved the families Gadidae, as well as several subfamilies, and Merlucciidae with strong support. viii The putative Lotinae subfamily clade was not resolved in this analysis and suggests that further study is needed to investigate the monophyly of this group. The three dorsal fins and two anal fins morphological states as well as the life history characteristic of the absence of an egg oil globule were all found to be characteristic of the Gadinae, the most derived clade of the Gadoidei. ix GENERAL INTRODUCTION Molecular techniques play an important role in fish ecology research and fisheries management. Molecular methods are useful at multiple organizational levels including communities, populations and individuals. These methods are also applicable across multiple taxonomic levels and can be used to explore relationships between families, genera, species and populations within a single species. Population ecology and genetics are essential in fisheries management (Hare et al. 2011). Population genetics studies have the ability to estimate population

Box 500, 21000 Split, Croatia. * Corresponding Author: Tel.: +385.20 445868; Fax: ; Received 20 November 2013 E-mail: [email protected] Accepted 24 January 2014 Abstract The forkbeard, Phycis phycis (Linnaeus, 1766), is a species widely distributed throughout the Mediterranean and Adriatic Sea and although it is of great importance for fishing industry, little is known about its reproductive characteristics. This study provides first data on reproductive characteristics of this species in the Mediterranean, important for management and stock assessment. For this purpose a total of 550 individuals ranging from 19.9 to 45.8 cm in total length were collected monthly in a period of one year using trammel nets. Sex ratio of males to females was 0.62:1. The estimated length where 50% of analysed individuals were sexually mature was 30.98 cm for females and 32.98 cm males. The peak value of gonadosomatic index was recorded in November and continued throughout the December, indicating the highest spawning activity. This period is characterized by presence of oocytes with migrated nucleus and yolk coalesces in ovary and spermatozoa in testes.

  • Molecular Systematics of Gadid Fishes: Implications for the Biogeographic Origins of Pacific Species
    Color profile: Disabled Composite Default screen 19 Molecular systematics of gadid fishes: implications for the biogeographic origins of Pacific species Steven M. Carr, David S. Kivlichan, Pierre Pepin, and Dorothy C. Crutcher Abstract: Phylogenetic relationships among 14 species of gadid fishes were investigated with portions of two mitochondrial DNA (mtDNA) genes, a 401 base pair (bp) segment of the cytochrome b gene, and a 495 bp segment of the cytochrome oxidase I gene. The molecular data indicate that the three species of gadids endemic to the Pacific Basin represent simultaneous invasions by separate phylogenetic lineages. The Alaskan or walleye pollock (Theragra chalcogramma) is about as closely related to the Atlantic cod (Gadus morhua) as is the Pacific cod (Gadus macrocephalus), which suggests that T. chalcogramma and G. macrocephalus represent separate invasions of the Pacific Basin. The Pacific tomcod (Microgadus proximus) is more closely related to the Barents Sea navaga (Eleginus navaga) than to the congeneric Atlantic tomcod (Microgadus tomcod), which suggests that the Pacific species is derived from the Eleginus lineage and that Eleginus should be synonymized with Microgadus. Molecular divergences between each of the three endemic Pacific species and their respective closest relatives are similar and consistent with contemporaneous speciation events following the reopening of the Bering Strait ca. 3.0–3.5 million years BP. In contrast, the Greenland cod (Gadus ogac) and the Pacific cod have essentially identical mtDNA sequences; differences between them are less than those found within G. morhua. The Greenland cod appears to represent a contemporary northward and eastward range extension of the Pacific cod, and should be synonymized with it as G.

Histological aspects of the early development of the digestive system of burbot Lota lota L. (Lotidae, Gadiformes). Folia Biologica (Kraków) 64: 11-21. The ontogeny of the digestive tract was studied histologically in burbot, Lota lota L., from hatching to 42 days post-hatch (dph). At hatching, the digestive tract consisted of a straight tube with discernible digestive accessory glands (the liver and the pancreas) dorsally attached to the yolk sac. Most of the yolk sac reserves were consumed during the first 12 days and were completely depleted by 17 dph. The first PAS-positive goblet cells appeared at 6 dph, dispersed within the epithelium of the oesophagus and increasing substantially in number and distribution as development progressed. At 12 dph, the first vacuoles (neutral lipids) appeared in the intestine, indicating the functional absorption of nutrients from food. Differentiation of gastric glands was first noticed at 17 dph and was extensive by 27 dph. L. lota larvae have a morphologically complete digestive tract by 32 dph.

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).

  • South Carolina Department of Natural Resources
    FOREWORD Abundant fish and wildlife, unbroken coastal vistas, miles of scenic rivers, swamps and mountains open to exploration, and well-tended forests and fields…these resources enhance the quality of life that makes South Carolina a place people want to call home. We know our state’s natural resources are a primary reason that individuals and businesses choose to locate here. They are drawn to the high quality natural resources that South Carolinians love and appreciate. The quality of our state’s natural resources is no accident. It is the result of hard work and sound stewardship on the part of many citizens and agencies. The 20th century brought many changes to South Carolina; some of these changes had devastating results to the land. However, people rose to the challenge of restoring our resources. Over the past several decades, deer, wood duck and wild turkey populations have been restored, striped bass populations have recovered, the bald eagle has returned and more than half a million acres of wildlife habitat has been conserved. We in South Carolina are particularly proud of our accomplishments as we prepare to celebrate, in 2006, the 100th anniversary of game and fish law enforcement and management by the state of South Carolina. Since its inception, the South Carolina Department of Natural Resources (SCDNR) has undergone several reorganizations and name changes; however, more has changed in this state than the department’s name. According to the US Census Bureau, the South Carolina’s population has almost doubled since 1950 and the majority of our citizens now live in urban areas.
