Population demographics of Palaemon peringueyi (Macpherson 1990) (Decapoda: Palaemonidae) in a small intermittently open Eastern Cape estuary
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: PW FronemanThe population demographics of the caridean shrimp Palaemon peringueyi was investigated monthly at four sites over a period of one year in the small, intermittently-open Grants River Estuary situated on the south-east coastline of southern Africa. Mean total abundance and... -
Feeding dynamics of Palaemon peringueyi (Decapoda, Caridea) in the temporarily open/closed Kasouga Estuary, South Africa
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: PW Froneman --- Department of Zoology and Entomology, South Africa TO Henninger --- Department of Zoology and Entomology, South AfricaThe feeding ecology of the caridean shrimp Palaemon peringueyi in the temporarily open/closed Kasouga Estuary, Eastern Cape, was examined during summer and winter employing stomach fullness index (SFI) analysis. Mean SFI values for male and female shrimp during summer ranged... -
Fishing methods for sustainable shrimp fisheries in the Canary Islands (North-West Africa)
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: M Arrasate-López --- , Spain VM Tuset --- , Spain JI Santana --- , Spain A García-Mederos --- , Spain O Ayza --- , Spain JA González --- , SpainDuring the past 20 years, experimental cruises have been conducted around the Canary Islands (North-West Africa) to investigate the biodiversity of the deep-sea ecosystem and to explore new fisheries resources. Although pandalid shrimps were shown to be very abundant in... -
A chronic toxicity test protocol using Caridina nilotica (Decapoda: Atyidae) and the generation of salinity toxicity data
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: AR Slaughter CG Palmer WJ MullerSalinization of freshwater resources is an increasing global problem, yet there is a paucity of chronic salinity tolerance data linked to very few chronic toxicity test protocols. This research aimed to generate a chronic toxicity test protocol and protective salinity... -
The fishery for, and local distribution of, Aristeus antennatus (Risso 1816) (Crustacea: Dendrobranchiata) off western Algeria
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: S Mouffok A Kherraz D Bouras Z BoutibaThis study presents data on the local distribution and yield of red shrimp Aristeus antennatus (Risso 1816) from a new deep-water fishery on the western Algerian slope obtained from commercial trawl fisheries at Oran and Arzew ports between 1999 and... -
Simultaneous extraction of chitin and astaxanthin from waste of lobsters Jasus lalandii, and use of astaxanthin as an aquacultural feed additive
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: L Auerswald G GädeThis work investigates simple methods for simultaneous extraction of astaxanthin and chitin from industrial waste of the South African West Coast rock lobster Jasus lalandii. Removal of proteins from waste is the critical step to yield intact chitin and astaxanthin... -
Temporal and spatial variability in the abundance, biomass and distribution of Palaemon peringueyi (Decapoda: Crustacea) are influenced by biological but not physico-chemical factors in the permanently open Kariega Estuary, South Africa
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: NP Nyalungu --- South African National Parks, Cape Research Centre, South Africa AN Hodgson --- Department of Zoology and Entomology, South Africa PW Froneman --- Department of Zoology and Entomology, South Africa M Dopolo --- South African National Parks, Cape Research Centre, South Africa M Masubelele --- South African National Parks, Cape Research Centre, South AfricaBiological and physico-chemical factors affecting abundance and biomass of shrimp Palaemon peringueyi were investigated in 2010–2011 in the lower, middle and upper reaches of the freshwater-deprived permanently open Kariega Estuary. Shrimp abundance and biomass ranged from 0 to 88 ind... -
Toxicity evaluation of effluent from the de-oiling works of a decommissioned Nigerian crude oil pipeline using Palaemonetes africanus
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: NH Amaeze --- Ecotoxicology Laboratory, Department of Zoology, Nigeria FA Adetoro --- Ecotoxicology Laboratory, Department of Zoology, Nigeria OA Adegboro --- Ecotoxicology Laboratory, Department of Zoology, NigeriaOil industry activities often involve the cleaning and replacement of pipelines, usually resulting in the discharge of effluents into waterbodies. The toxicity of de-oiling effluent from a decommissioned crude oil pipeline in the Niger Delta region of Nigeria was assessed... -
Penaeid and carid community changes in the St Lucia estuarine lake system, South Africa, under low water level, extended closed periods and marine reconnection conditions
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: GP Tweddle --- Coastal Research Unit of Zululand, Department of Zoology, South Africa DP Cyrus --- Coastal Research Unit of Zululand, Department of Zoology, South Africa L Vivier --- Coastal Research Unit of Zululand, Department of Zoology, South AfricaPenaeid and carid communities were assessed in St Lucia over a wide range of saline conditions, water level conditions and mouth states, including a six-month marine connection and various connections to the Mfolozi Estuary. Samples were collected biannually in spring... -
A tale of records from Hakskeen Pan, the first record of Pumilibranchipus deserti Hamer and Brendonck, 1995 (Anostraca, Branchiopoda) from South Africa and the pursuit of a new world land speed record
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: E Meyer-Milne --- South African Environmental Observation Network, South Africa MC Mlambo --- Department of Freshwater Invertebrates, Albany Museum, South AfricaUntil now, Pumilibranchipus deserti was known from only one locality in Namibia. This paper reports the first record of this species from South Africa in Hakskeen Pan, Northern Cape, which represents a new, easterly range extension of the known distribution...
