Shallow coastal waters of the Volga river is a flooded feeding area for fish juveniles of nonmigratory fish species. There takes place annual downstream migration of fluvial anadromous fish species from spawning grounds of the Volga river to the Northern Caspian Sea. The most important factors determining the number and qualitative characteristics of fry fishes are the level of the Caspian Sea (currently having a tendency to the lowering), hydrological and thermal regimes of the Volga river. Researches were carried out in definite periods of time. In the summer-autumn period of 2012 fry fishes were presented by 19 species (13 of them were commercial species), which belonged to 9 families. The article gives data on all the commercial fish species. In the first decade of July the maximum number of fry fish was registered in the western part of the Volga outfall offshore - in box 247 (19.86 mln specimens/km2), in the eastern part - in box 142 (20.4 mln specimens/km2). The most populous were roach, red-eye, silver bream and bream; size-weight characteristics were better in the areas remoted from the Volga delta. In the third decade of July the quantitative indicators of fry fish on these areas decreased, size-weight characteristics greatly increased. In the second decade of October in the western part of the seaside there were registered increased pre-wintering concentrations of fish juveniles, their qualitative indicators increased, which is evidence to favorable feeding conditions in 2012.

This study is focused on evaluating the trace metal levels in water and tissues of two commercial fish species Arius thalassinus and Pennahia anea that were collected from Kapar and Mersing coastal waters. The concentrations of Fe, Zn, Al, As, Cd and Pb in these coastal waters and muscle, liver and gills tissues of the fishes were quantified. The relationship among the metal concentrations and the height and weight of the two species were also examined. Generally, the iron has the highest concentrations in both water and the fish species. However, Cd in both coastal waters showed high levels exceeding the international standards. The metal level concentration in the sample fishes are in the descending order livers > gills > muscles. A positive association between the trace metal concentrations and weight and length of the sample fishes was investigated. Fortunately the level of these metal concentrations in fish has not exceeded the permitted level of Malaysian and international standards.

Seagrasses in the Air Bangis Archipelago, west coast of Sumatra were found growing in sandy muddy substratesof the shallow coastal waters at depth of 0.3-2.5 m, dominated by degraded coral reefs around the off-shoreislands. Two species; Enhalus acoroides (L.f) Royle and Thalassia hemprichii (Ehrenb) Aschers were observed atPulau Unggas, Pulau Pasir Panjang and Teluk Tapang. Halodule uninervis (Forssk) Aschers was observed in twolocations; Pasir Panjang and Teluk Tapang. The occurrence of this species is unknown previously and therefore itis a new flora record for Sumatra. With this new record, Sumatra has six species of seagrasses, contributing tohalf of total number of seagrasses occurring in Indonesia. According to leaf width measurements, two morphologicalvariants (narrow and wide leaved) can be distinguished for Halodule uninervis. In addition, descriptions of thespecies and their habitat characteristic are provided.

Herein we present new records of three freshwater fish species (Hasemania crenuchoides, Hyphessobrycon balbus and Oligosarcus planaltinae) considered restricted to Central Brazil and previously known only for the upper Rio São Bartolomeu sub-basin. Our data expand their range to other sub-basins in the Distrito Federal, including Sobradinho, Bananal, Santa Maria-Torto, Gama and Ribeirão Santana sub-basins.

A check-list of the coastal fishes of Madeira Island is presented. The species Rhincodon typus, Megalops atlanticus, Apterichtus caecus, Apterichtus sp., Chelidonichthys lucernus, Caranx crysos, Lutjanus goreensis, Crystallogobius linearis, and Canthidermis sufflamen are recorded for the first time from Madeira waters. We have recognized 13 previous records as identification errors or registration errors and indicate 14 other records as doubtful. Including the nine new records, we list 226 species from the coastal waters of Madeira Island.

A checklist of the fishes of Ascension Island is presented. The speciesRhincodon typus,Alopias superciliosus,Isurus oxyrinchus,Carcharhinus obscurus,Galeocerdo cuvier,Sphyrna lewini,Hexanchus griseus,Manta birostris,Gymnothorax vicinus,Hippocampussp.,Epinephelus itajara,Cookeolus japonicus,Apogon pseudomaculatus,Phaeoptyx pigmentaria,Remora albescens,Caranx bartholomaei,Carangoides ruber,Decapterus tabl,Seriola dumerili,Thalassoma sanctaehelenae,Cryptotomussp.,Ruvettus pretiosus,Acanthocybium solandri,Auxis rochei,Auxis thazard,Euthynnus alletteratus,Katsuwonus pelamis,Thunnus alalunga,Thunnus obesus,Xiphias gladius,Istiophorus platypterus,Kajikia albida,Makaira nigricans,Tetrapturus pfluegeri,Hyperoglyphe perciformis,Schedophilussp.,Cantherhines macrocerus,Sphoeroides pachygasterandDiodon eydouxiiare recorded for the first time from Ascension Island. We have recognized two previous records as identification errors and indicate 11 other records as doubtful. Including the 40 new records, we now list 173 fish species from Ascension Island, of which 133 might be considered ‘coastal fish species’. Eleven of these (8.3%) appear to be endemic to the island and a further 16 species (12%) appear to be shared endemics with St Helena Island.
