It is thus hypothesized that nypa palm presence in mangrove forest will impact their fish spawning ability due to the reduction in plankton population. A total of four stations were chosen: station 1 (open water), Station 2 (nypa palm dominant), station 3 (Rhizophora and Avicennia dominant), Station 4 (Mixed forest). Results of water quality parameters include; pH (6.99 ± 0.16), temperature (28.20°C ± 0.05°C), DO (4.71 ± 0.18 mg/L), conductivity (19.52 ± 0.20 µm/s), salinity (10.76 ± 0.07 ppt) and TDS (13.45 ± 0.27 ppt). Mean values of the physico-chemical parameters were not significantly different from each other (P > 0.05). In all 737 zooplankton in eleven genera were collected. Copepoda dominated with 75.1%. Similarly, 4774 phytoplankton in six taxa were collected. Bacilliarophyceae dominated with 87.45%. Shannon Weiner index across the stations was highest in station 4 (0.36) and lowest in station 1 (0.33). Margalef’s index was highest in stations 2, 3, and 4 (3.48) and lowest in station 1 (2.67). Pielou’s index of evenness was highest in station 4 (0.099) and lowest in station 1 (0.089). The composition and abundance of plankton showed no significant difference across the four stations (P > 0.05). This implies that the presence of Nypa fruticans (Wurmb) did not have negative impact on the abundance and diversity of plankton.","PeriodicalId":22529,"journal":{"name":"The international journal of marine science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79977813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to investigate the levels of heavy metal in water, sediment and tissues of Sarotherodon melanotheron , from the Upper Bonny Estuary in the Niger Delta and to evaluate their human health implications. Water, sediment and S. melanotheron samples were collected from 5 different stations namely; Okochiri Creek (S1), Ekerekana Creek (S2) - Point of industrial effluent discharge (POD), Okari-Ama Creek (S3), Ogoloma Creek (S4) and Bonny Estuary (Control). The levels of Cr, Ni, Zn, V, Cd, Pb, Hg, and As were analysed following Standard Procedures using Atomic Absorption Spectrophotometer (AAS). Metals analysed were below detectable limit (0.001 mg/L) in water while metals such as Pb, Cr, Ni, Zn and V were below permissible limit in sediment. Ecological indices indicated that the sediment of the study area was unpolluted. The levels in the tissues (gill, muscle and liver) showed varying concentrations. Ni concentration in the tissues exceeded FAO/WHO permissible limits, Cr was above permissible limit in most tissues, while Pb was only detected in the muscle of S. melanotheron from Okari-ama Creek (S3). Zn and V were below the FAO/WHO permissible limit. Cd, As, and Hg were not detected in all samples. BSAF showed bio-accumulative potentials in the tissues. Further calculations on the risk associated with consumption of S. melanotheron showed that HQ and HI were <1 which showed no threat to public health. However, more studies on heavy metals and proper monitoring of the creeks should be encouraged by regulatory agencies in Nigeria to give informed decisions from risk assessments.","PeriodicalId":22529,"journal":{"name":"The international journal of marine science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79693123","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective: Two species of Gnathostomatidae are recorded, Gnathostoma sp and Gnathostoma binucleatum Almeyda-Artigas, 1991. The gross clinical pathology examination showed extensive damage to the host intestinal tissue, including epithelial necrosis, hemorrhaging, worm encapsulation, and the presence of live larvae encysted and adult in skeletal muscles of fishes causing lesions including mild hyperplasia of fibrous connective tissue around the parasite. The cross examination of fish intestines revealed food items containing parts of the animal body, appendages, Chela, and parts of the carapace of crustaceans. Most food items found in all months also including annelids (polychaetes) in high percentage in November Volume of food items were related to fish size. Juveniles appear to feed mainly on crustaceans and the adults mainly feed on crustaceans, molluscs, polychaetes, echinoderms, and teleosts, among other items. The summer was apparently not the season of parasite infection. The prevalence of infection with Gnathostoma binucleatum was low (6 of 57 fish), whereas the prevalence of infection with Gnathostoma sp. was 3 of 57 fish. These findings of Gnathostomatids represent new records of these parasites in Arabian Gulf fishes. More study needed to recognize on the larval stage parasite infection and their clinic pathology to provide a basic understanding of the general principles of the pathogenesis and pathology of Gnathostomiasis, and the relationship between fish length, food items and infection.","PeriodicalId":22529,"journal":{"name":"The international journal of marine science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89034036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
