“…In Milnerton Lagoon, there have been no previous surveys assessing total standing stock of the worm, however, this polychaete is known from this system from as far back as 1954 (Millard & Scott 1954). In 2014 this worm was recorded under Milnerton Bridge and alongside Milnerton Golf Club (Viskich et al 2016).…”

“…Historically, F. enigmaticus abundance and distribution has fluctuated seasonally in Milnerton Lagoon (Viskich et al 2016). The invasive tube worm was found in both summer and winter of 1954 (Millard & Scott 1954). In 1974 there was a significant increase in the prevalence of the worm and it was classified as "abundant" (Viskich et al 2016).…”

Benthic studies were undertaken in two mangrove-lagoons on the south coast of Cuba. Both lagoons are approximately 30-50 cm deep and the tidal range is 15-20cm. There is little influx of fresh water, and the lagoons are normally euhaline. Most of the lagoon bottom is not colonized by plants, although filamentous algae (Cladophma and Enteromorphu spp.) and Thlassia testzddium grow in a few places. Meiobenthic organisms account for 92 0,b of the invertebrates in the benthic zone of the lagoon. The five most common taxn (Nematoda, Copepoda, Tanaidacea, Oligochaeta, Polychaeta) account for 88-94 0 ; of the total number of individuals in Tolete Lagoon and in Basto Lngoon the five most common taxa (Nematoda, Copepoda, Ostracoda, Amphipoda, Polychaeta) account for 97-98 (1 ,,. Biomasses were 26.8 g/m? in Tolete and 20.2 g/m2 in Basto Lagoon.The dominant taxon on the roots of Khimphora nlangle is Crustarea (Balanus eburneus, B. recurrus and Corophizon insidiosurn), accounting for over 60 (1 of the total number of individuals. They are fol loned by molluscs (Cmsaostren rhizophorn) and the polychaetes (Berpulids).

“…There arc, however, very few data concerning fish inhabiting estuaries and lagoons on the west coast. Millard & Scott (1954) provide brief notes on the species composition and distribution of fish in Milnerton estuary and Whitfield, Beckley, Bennett, Branch, Kok, Potter & Van dcr Elst (1989)…”

The fish community of the berg river estuary and an assessment of the likely effects of reduced freshwater inflows

Data concerning the species composition, abundance and distribution of fishes inhab~ing the Berg River estuary are presented and used to assess the value of the estuary to fish, and the likely effects of reduced freshwater inflows. A total of 31 species was recorded, eight of which were classified as estuarine residents, 11 as marine estuarine-opportunists, six as marine stragglers and six were freshwater species. Liza richardsonii, an opportunist, was the most abundant (54% N) and widely distributed species encountered during the winter and summer seine-net surveys. Three other species (all residents) contributed more than 10% of the total catch; Atherina breviceps and Caffrogobius nudiceps occurring most abundantly in the lower estuary, and Gilchriste/la aestuaria in the middle estuary. The low number of species compared with estuaries in other regions of the South African coast reflect a well-established marine biogeographical trend. The higher proportions of resident species, entirely dependent species and partially dependent species suggest, however, that west coast estuaries may be more important to the fish that inhabit them than are estuaries in other regions. It is concluded that the fish community of the estuary is already suffering the effects of habitat degradation and that further reductions in freshwater inflows are not desirable. Data betreffende die spesiessamestelling, talrykheid en verspreiding van visse wat die Bergriviermond bewoon, word aangebied en gebruik in 'n raming van die waarde van die mend vir die bewonende visse, en die moontlike gevolge van verminderde varswaterinvloei. 'n Totaal van 31 spesies is aangeteken, agt waar• van geklassifiseer is as mondinwoners. 11 as mariene trekvisse, ses as mariene swerwers en ses as vars• watersoorte. Liza richardsonii, 'n trek vis, was die volopste (54% N) en mees wydverspreide spesie wat te9ge• kom is gedurende die winter• en someropnames. Die ander spesies (almal inwoners) het meer as 10% byge• dra tot die totale vangs, met Atherina breviceps en Caffrogobius nudiceps wat volopste in die laer-, en Gilchristella aestuaria in die middelgedeeltes van die strandmeer, voorkom. Die klein aantal spesies weer-spie91 'n geed vasgelegde mariene biogeografiese neiging. Die grater proporsie van inwonerspesies, totaal afhanklike en gedeeltel1k afhanklike spesies suggereer egter dat Weskusriviermonde belangriker mag wees vir die vi sse wat hulle bewoon as riviermonde in ander streke. Die gevolgtrekking word gemaak dat die visgemeenskap van die riviermond reeds onder die gevolge van habitatvernieling ly en dat verdere verminderings in varswaterinv1oei onwenslik is.
