“…D. angolensis is widely distributed in the Eastern Central Atlantic along the West Coast of Africa from Morocco to Angola, including Canary Islands (Rico et al 1995). The economic value of D. angolensis is driving overfishing in some regions, with substantial (10%/year) population decline (Aheto et al 2012). Thus, the species is now classified as 'Near Threatened' in the Red List of Threatened Species (Pollard et al 2014).…”

The complete mitochondrial genome of the Angolan dentex (Dentex angolensis, Poll and Maul, 1953) is 16.581 bp in length and contains 13 protein-coding genes, 22 transfer RNA genes, and 2 ribosomal RNA genes. The overall base composition of D. angolesis mtDNA is: 27.4% for A, 28% for C, 16.7% for G, 27.9% for T. Phylogenetic analysis indicated that D. angolensis is most closely related to D. tumifrons. Whole genome sequencing of D. angolensis mitochondrial DNA will contribute to improving knowledge about Sparidae evolution.

“…This study was conducted from February 2016 to June 2018 in Elmina (5°5 0 N 1°21 0 W) ( Fig. 1a & b) which is the third largest sh landing site in Ghana (Aheto et al, 2012). Elmina was purposively selected because it contributes about 15% of the country's total sh output (Hen Mpoano, 2015a) and has the highest intensity of saiko operations in the country (Hen Mpoano, 2015b).).…”

Increasing global seafood demand over the last couple of decades has resulted in overexploitation of certain fish species by both industrial and small-scale artisanal fishers. This phenomenon has threatened the livelihoods and food security of small-scale fishing communities especially in the West African sub-region. In Ghana, fish transshipment (locally referred to as saiko) has been catalogued as one more negative practice that is exacerbating an already dire situation. The goal of this study was to characterise transshipped fish species landed in Ghana on the basis of composition, habitat of origin, maturity and conservation status on the IUCN list of threatened species to enhance understanding of the ecological implications of the practice and inform regulatory enforcement and policy formulation. Using identification manuals, morphometric and gravimetric analyses among others, data on saiko fish samples landed at Elmina in the Central Region of Ghana were collected at bi-weekly intervals between November 2016 and June 2017. A total of sixty-eight (68) fish species from 44 families comprising finfish and shellfish of pelagic, demersal, benthopelagic, and reef-associated fishes were identified. The round scad (Decapterus punctatus), the mackerel scad (Caranx rhonchus), the round sardine (Sardinella aurita) and the red pandora (Pagellus bellottii) were the numerically dominant species recorded. By habitat classification, 44 species (65%) were demersals while 6 species (9%) were pelagic and 6 species (9%) were reef-associated. Majority of the demersal species were juveniles while composition of juveniles among the pelagic species ranged between 67% - 84%. In addition, 6 (10%) of the recorded species were either vulnerable or near threatened on the IUCN red list of threatened species. It could be deduced from these observations that the recruitment of juveniles into the small pelagic fish stocks may be compromised and possibly lead to the future collapse of such fishery. The practice is also inadvertently a clear threat to the marine ecosystem, and sustainable fish production in Ghana.

“…The dependency on fishing, however, makes it very difficult to implement effective strategies to prevent over-exploitation by fishermen and local communities and this has resulted in the decline of fish populations and other biota associated with seagrass. Other studies, too, have reported that small-scale fishing activities have had a negative impact on seagrass and other biota associated with seagrass in East Lombok (Satyawan et al, 2014), in reef flats and seagrass bed areas has reduced the population of the biota in the coastal waters (McCloskey and Unsworth, 2015) and high rates of exploitation mean that stocks generally cannot sustain expected levels of economic return (Aheto et al, 2012) and a relationship between the significant decline in catches in Indonesian waters and damage to seagrass beds . Furthermore, many of seagrass habitats damage caused to from community activities, commercial fishing and aquaculture (Brigitta et al, 2014).…”

Seagrass ecology contributes to the preservation of fish and other biota diversity and is also an important livelihood source for fishermen and local communities. The purpose of our research was (1) to determine the source of the threats toseagrass ecology and to the ecological services it provides for the sustainability of fish resources and (2) to determine the main indicators defining the conservation needs of seagrass in the study area. Data were collected through direct observation, questionnaires, interviews and discussions. Data for fish in the seagrass bed research sites were obtained using mini-trawlers belonging to local fishermen. All data were analyzed using descriptive statistical analyses. The results showed that seagrass beds play an important role in fish ecology and that local livelihoods were highly dependent on small-scale fishing. However, fishermen and local communities also constituted the two main threats to the preservation and sustainability of fish and other biota in the area. Our results found, too, that there is a scarcity of some types of biota: some fish species, mollusks, crabs, see-urchin and some types of sea cucumber were very difficult to find in the seagrass beds that were the focus of our study. Our conclusion is that, given the scarcity of fifteen species of fish, as well as of other biota and the lack of diversity in fish food in our study area, it is imperative that seagrass conservation becomes an important priority for conservation interventions.
