For this purpose, 1304 specimens of family Teraponidae were collected during January 2013 to December 2014 from commercial landings at Karachi Fish Harbour. Three species of family Teraponidae (Terapon jarbua, T. puta and T. theraps) were investigated from the samples. The results of statistical analysis of selected parameters of ctenoid scales (i.e., length of scale and width, radius, horizontal and vertical row of ctenii and number of radii) of Teraponid species proved the significance of scales in correct identification of Teraponid species. The results of linear relationship and principal component analysis-PCA of selected scale parameters shows the significance of selected scale parameters in fish identification. The frequency distribution pattern of Teraponid species was recorded as 51.84% for T. jarbua and 47.70% for T. puta in total catches during the study period (January 2013 to December 2014). The occasional catch of T. theraps shows the absence of this species in commercial catches of Karachi coast. The population parameters of Teraponid species indicates a risk of over exploitation of these species at Karachi coast, Pakistan. Results for length-weight relationships shows that the value of regression coefficient (b) was closer to the ideal value i.e. b=3 hence shows the isometric growth in T. jarbua however, T. puta indicates a positive allometric growth pattern (b>3). The results of condition factor and relative condition factor indicated the good health of Teraponid species. The Macroscopic examination of male and female gonads and gonadosomatic index confirms that T. jarbua has two spawning period from April to August and November while, T. puta has a prolonged spawning period with two distinct peaks in April and November. The results for sex ratio illustrate that females were more numerous than males in both Teraponid species (i.e., T. jarbua and T. puta). i ii LIST OF TABLES LIST OF TABLES S. No. Topics Pg.

    Biodiversity Summary for NRM Regions Species List What is the summary for and where does it come from? This list has been produced by the Department of Sustainability, Environment, Water, Population and Communities (SEWPC) for the Natural Resource Management Spatial Information System. The list was produced using the AustralianAustralian Natural Natural Heritage Heritage Assessment Assessment Tool Tool (ANHAT), which analyses data from a range of plant and animal surveys and collections from across Australia to automatically generate a report for each NRM region. Data sources (Appendix 2) include national and state herbaria, museums, state governments, CSIRO, Birds Australia and a range of surveys conducted by or for DEWHA. For each family of plant and animal covered by ANHAT (Appendix 1), this document gives the number of species in the country and how many of them are found in the region. It also identifies species listed as Vulnerable, Critically Endangered, Endangered or Conservation Dependent under the EPBC Act. A biodiversity summary for this region is also available. For more information please see: www.environment.gov.au/heritage/anhat/index.html Limitations • ANHAT currently contains information on the distribution of over 30,000 Australian taxa. This includes all mammals, birds, reptiles, frogs and fish, 137 families of vascular plants (over 15,000 species) and a range of invertebrate groups.

    Catalogue of Some Saltwater and Freshwater Fish Species of the Niger Delta Region of Nigeria Ekinadose Orose, Edafe Odioko and Okechukwu Kenneth Wokeh * Department of Animal and Environmental Biology, Hydrobiology and Fisheries Unit, University of Port Harcourt, PMB 5323, Port Harcourt, Rivers State, Nigeria. World Journal of Advanced Research and Reviews, 2021, 09(03), 056–084 Publication history: Received on 29 January 2021; revised on 27 February 2021; accepted on 01 March 2021 Article DOI: https://doi.org/10.30574/wjarr.2021.9.3.0075 Abstract The study was done to review some saltwater and freshwater fish species in the Niger Delta region of Nigeria. The Niger Delta is one of the most prominent regions in Nigeria, endowed with several water bodies that are distributed as freshwater like rivers, lakes, streams and creeks. These freshwater ecosystems in the region, are abundantly endowed with fish species such as Clarias gariepinus, Pila ovate, Labeo coubie, Synodontis budgetti and Synodontis eupterus. Apart from the freshwaters, the region also has vast marine ecosystem with abundance of fish species such as Elops lacerta, Mugil cephalus, Thais coronata, Periophthalmus papilio, Tympanotonus fuscatus, and Sardinella maderensis. Unfortunately, many of these fish species are endangered due to constant pollution in the Niger delta regional coastal environment. As a result, it is important to document some available freshwater and marine water fish species which will serve as a reference material for both academics and research institutions, should any of the fish species go into extinction. Keywords: Extinction, Coastal Waters, Marine Diversity, Niger Delta 1. Introduction Nigeria’s coastal waters fall within the Guinea Current Large Ecosystem (GCLME), a shared resource by all the coastal West African countries.

Center Laboratory for Aquaculture Research (CLAR). ABSTRACT Age, growth, and mortality of Terapon puta were studied from a small scale fishery of Bardawill lagoon, (North Sinai, Egypt). 2777 specimens (6.9 to 17.5 cm total Length and 14.1 to 55.9 g total weight), were collected from April to December, 2016. The relationship between length and weight was W = 0.0186L2.7809. Age was determined by otoliths and age groups 0 to 4 years were observed. Growths in length and weight at the end of each year were calculated. The growth parameters of von Bertalanffy equation were calculated as (L∞ = -1 -1 18.50, K = 0.3554 yr and t0 = -1.15 yr ). Growth performance index was calculated (φ = 2.08 for length and φ= 0.75 for weight). Mortality rates were 0.90 yr-1, 0.35 yr-1and 0.55yr-1 for total, natural and fishing mortality, respectively. The currently exploitation rate E = 0.61. The probability of capture (Lc50 = 12.7). The higher of fishing mortality verses natural mortality observed for T. puta indicates that its stock was overexploited in Bardawill lagoon.

Eight species were analyzed: these include one endemic species (Leiopotherapon plumbeus); one introduced species (Bidyanus bidyanus); and six native species (Terapon jarbua, Terapon puta, Terapon theraps, Pelates quadrilineatus, Helotes sexlineatus, and Mesopristes cancellatus). Primers were designed to amplify and sequence the 12S rRNA (12S), cytochrome c oxidase subunit I (COI), and cytochrome b (CytB) genes. The concatenated 12S, COI, and CytB sequences (3529 bp) were used to construct the phylogeny of the tigerperches using Maximum Parsimony (MP), Neighbor Joining (NJ), Maximum Likelihood (ML), and Bayesian Inference (BI) analyses. All four analyses supported the monophyly of tigerperches. Except for the MP tree, all phylogenetic trees showed that Terapon jarbua was the first to have diverged from the rest of the tigerperch species examined. The congeneric T. jarbua, T. puta and T. theraps did not group together, suggesting their non-monophyly. However, SH test on the unconstrained (actual observation) and constrained (the three congeneric species were forced to group together) NJ trees showed no significant difference (p = 0.55).
