  • VARIATION in SETTLEMENT and LARVAL DURATION of Klng GEORGE WHITING, SILLAGINODES PUNCTATA (SILLAGINIDAE), in SWAN BAY, VICTORIA, AUSTRALIA
    BULLETIN OF MARINE SCIENCE, 54(1): 281-296, 1994 VARIATION IN SETTLEMENT AND LARVAL DURATION OF KlNG GEORGE WHITING, SILLAGINODES PUNCTATA (SILLAGINIDAE), IN SWAN BAY, VICTORIA, AUSTRALIA Gregory P. Jenkins and Helen M. A. May ABSTRACT Otoliths were examined from late-stage larvae and juveniles of King George whiting, Sillaginodes punctata, collected from Swan Bay in spring 1989. Increments in otoliths of larval S. punctata are known to be formed daily. A transition in the microstructure of otoliths from late-stage larvae was apparently related to environmental changes associated with entry to Port Phillip Bay. The pattern of abundance of post-larvae of S. punctata in fortnightly samples supported the contention that the transition was formed immediately prior to "set- tlement" in seagrass habitats. Backcalculation to the otolith transition suggested that five cohorts had entered Swan Bay, each approximately 10 days apart, from late September to early November. Stability of this pattern for juveniles from sequential samples indicated that otolith increments continued to be formed daily in the juvenile stage. The pattern of settlement was consistent for two sites within Swan Bay. The larval phase of King George whiting settling in Port Phillip Bay was extremely long and variable, ranging from approximately 100 to 170 days. Age at settlement was more variable than length, and growth rate at settlement was I I extremely slow, approximately 0.06 mm ·d- • • Backcalculated hatching dates ranged from April to JUly. July. Increment widths in the larval stage suggest that growth slows after approxi- mately 45 to 75 days; beyond which individuals are in a slow growth, competent stage of 40 to 100 days.

(2019). Diversity and length-weight relationships of Blenniid Species (Actinopterygii, Blenniidae) from Mediterranean Brackish Waters in Turkey. Aquatic Sciences and Engineering, 34(3), 96-102. ABSTRACT This study aims to determine the species composition and range of Mediterranean Blennies (Ac- tinopterygii, Blenniidae) occurring in river estuaries and lagoon systems of the Mediterranean coast of Turkey, and to characterise the length–weight relationship of the specimens. A total of 15 sites were surveyed from November 2014 to June 2017. A total of 210 individuals representing 3 fish species (Rusty blenny-Parablennius sanguinolentus, Freshwater blenny-Salaria fluviatilis and Peacock blenny-Salaria pavo) were sampled from five (Beşgöz Creek Estuary, Manavgat River Es- tuary, Karpuzçay Creek Estuary, Köyceğiz Lagoon Lake and Beymelek Lagoon Lake) of the locali- ties investigated. The high juvenile densities of S. fluviatilis in Karpuzçay Creek Estuary and P. sanguinolentus in Beşgöz Creek Estuary were observed. Various threat factors were observed in five different native habitats of Blenny species. The threats on the habitat and the population of the species include the introduction of exotic species, water ORCID IDs of the authors: pollution, and more importantly, the destruction of habitats.

  • Parallel Adaptations of Japanese Whiting, Sillago Japonica Under Temperature Stress
    Parallel adaptations of Japanese whiting, Sillago japonica under temperature stress Zhiqiang Han1, Xinyu Guo2, Qun Liu2, Shanshan Liu2, Zhixin Zhang3, shijun xiao4, and Tianxiang Gao5 1Affiliation not available 2BGI-Shenzhen 3Tokyo University of Marine Science and Technology Graduate School of Marine Science and Technology 4Tibet Academy of Agricultural and Animal Husbandry Sciences 5Zhejiang Ocean University February 9, 2021 Abstract Knowledge about the genetic adaptations of various organisms to heterogeneous environments in the Northwestern Pacific remains poorly understood. The mechanism by which organisms adapt to temperature in response to climate change must be determined. We sequenced the whole genomes of Sillago japonica individuals collected from different latitudinal locations along the coastal waters of China and Japan to detect the possible thermal adaptations. A total of 5.48 million single nucleotide polymorphisms (SNPs) from five populations revealed a complete genetic break between the China and Japan groups. This genetic structure was partly attributed to geographic distance and local adaptation. Although parallel evolution within species is comparatively rare at the DNA level, the shared natural selection genes between two isolated populations (Zhoushan and Ise Bay/Tokyo Bay) indicated possible parallel evolution at the genetic level induced by temperature. Our result proved that the process of temperature selection on isolated populations is repeatable. Additionally, the candidate genes were functionally related to membrane fluidity in cold environments and the cytoskeleton in high-temperature environments. These results advance our understanding of the genetic mechanisms underlying the rapid adaptations of fish species. Projections of species distribution models suggested that China and Japan groups may have different responses to future climate changes: the former could expand, whereas the latter may contract.

Australia ABSTRACT A review of the fishes of the family Sillaginidae from Indian waters is given with a description of a new species of Siliago. A key to the genera and species is provided. INTRODUCTION TUB sandborers or Indo-Paciiic sillagos of the family Sillaginidae are popular food fishes captured by seine-net, cast-net. Gill-net, lift-net and trawl-net in inshore and estuarine waters of the Indo-Pacific region from South Africa to northern Japan. The species are most numerous in Australian waters and are being reviewed by the author. In India they are known by a variety of local names and form a small but important fishery. I am deeply grateful to Dr. W. Fischer of the Fisheries Resources Service of FAG, Rome, for the opportunity to participate in the FAO/DANIDA Expert Consultation Programme at the Central Marine Fisheries Research Institute, Cochin, 1980. During this Programme many sillaginids were examined and Siliago vincenti discovered. My colleagues at Cochin assisted me in collecting and photographing the new species. Dr. E. G. Silas, Director, CMFRI, Cochin made early publica­ tion of this paper possible and made facilities available for the examination and illustration of specimens. To the staff of CMFRI, especially Mr. A, Noble and the artist Mr. A. Muniyandhi, my appreciation for their generous assistance. To my friend Mr. S; G. Vincent of CMFRI my thanks for his valuablp assistance in coUectirig specimens, obtaining information for this study recognising the two species in the field and assisting with the measurements.

Selection force analysis in seven Sillago species detected 44 genes positively selected relative to other Perciform fishes. The results of the present study can be used as a reference for the further adaptive evolution study of Sillago species. Abstract: Sillago species lives in the demersal environments and face multiple stressors, such as localized oxygen depletion, sulfide accumulation, and high turbidity. In this study, we performed transcriptome analyses of seven Sillago species to provide insights into the phylogeny and positively selected genes of this species. After de novo assembly, 82,024, 58,102, 63,807, 85,990, 102,185, 69,748, and 102,903 unigenes were generated from S. japonica, S. aeolus, S. sp.1, S. sihama, S. sp.2, S. parvisquamis, and S. sinica, respectively. Furthermore, 140 shared orthologous exon markers were identified and then applied to reconstruct the phylogenetic relationships of the seven Sillago species. The reconstructed phylogenetic structure was significantly congruent with the prevailing morphological and molecular biological view of Sillago species relationships.
