    Description: A preliminary survey of fish species composition in Igbedi Creek was carried out between July and September, 2007. Fish samples were collected from the fishermen's catches operating in the Creek and its distributary Ogoubiri River. Collected fish specimens were identified in the laboratory using standard identification keys. Thil1y-seven (37) fish species belonging to 17 families were observed. The most abundant families were the Mochokidae with seven (7) species which constituted 23.79% of the total sample collected followed by the Clariidae (10.78%) and Mormyridae (10.04%).

    Description: A 14-day quick appraisal fisheries survey of the Brass River area was conducted from 8th-21st June 2005 to collect information on fish species, fish catch and fishing craft. Total fish catch was estimated to be 11,086.12kg. Out of a total of 15 families and 43 species caught in the area, the Sciaenidae (Pseudotolithus typus, P.elongatus, P.senegalenensis) contributed 37%, the Polynemidae (Polydactylus quadrifilis) 26%, and Bagridae (Chrysichtyes nigrodigitatus) accounted for 17% of the total fish landings. The landings at the Coastal Marine Waters were about 66 % while the catch from gill nets constituted 68% of the total fish landings, followed by traps with 15%, hooks and lines landed 11 % while seine nets and cast nets contributed 5% and 1 % respectively to total fish landings. Four types of crafts were used in the Brass River Fisheries including the Ghana boat, plank boat (with or without engine), fiberglass speed boat and the dug-out canoe. In view of high industrial and commercial activities and especially threats from oil and gas pollution, it is recommended that the fisheries of the Brass area be properly investigated.

    Occurrence and distribution of macrobenthic invertebrates in the lower Taylor Creek, Bayelsa State (2021)
    FISON | Lagos (Nigeria)
    In:  http://aquaticcommons.org/id/eprint/24231 | 19325 | 2018-05-19 07:24:40 | 24231 | Fisheries Society of Nigeria

    Description: The occurrence and distribution of macrobenthic invertebrates were investigated in relation to water flow and nature of bottom in the Lower Taylor Creek. Benthic samples were collected from 3 stations with Eckman grab, fixed in 4% formaldehyde solution with Rosebengal stain, sorted and preserved in 70% ethanol and identified in the laboratory under stereo or compound microscopes. Five (5) families of macrobenthic invertebrates (Tubificidae, Chironomidae, Naididae, Sphaeridae (Bivalvia) and Lumbricidae) comprising 7 species occurred in the samples. Tubificids formed 69% of the macrobenthic fauna and were distributed in all Stations. Station III with least flow and soft mud bottom had more significant number of organisms (p 〈0.05) than Stations I and II with silt and clay and silt and sand bottoms respectively. Water flow and nature of bottom, influenced the occurrence and distribution of macrobenthos in the Lower Taylor Creek.
