Eurytemora affinis. 1, two males have seized the same female (photograph by Ian Riddell); 2, female with about 2 spermatophores attached.Nota: A male first seizes a female by her posterior abdomen or caudal rami using his geniculate right antennule. Seizure of a female's antennule or swimming legs occasionally occurs. Several males sometimes seize a single female, but only one copulate with her at one time. Seizure can last for from 30 secondes to over an hour. Females commonly bear more than one spermatophore. Observations suggest that they resulult from a series of matings with males, rather than from a single prolonged mating. |

The density (ind./10 l) of nob-ovigerous females of Eurytemora hirundoides (= E affinis) at different depths at the Archipelago Sea on the SW coast of Finland in June August 1977 at 0900 h.
Nota: The distribution of ovigerous and non-ovigerous females followed a constant pattern through summer and early autumn. Non-ovigerous females were distributed throughout the water column, preferring the deeper parts. Ovigerous females were also abundant below 20 m but they almost totally avoided the surface layer above 20 m. The difference wqs statiscally significant.
When Eurytemora ovigerous and non-ovigerous females were presented for fish (Gasterosteus aculeatus, important planktivore predator) in an abundance corresponding to that found in nature (9 ind./750 ml), no selection between the two types was found. That was also the result when females and males were offered in densities much higher than natural (corresponding 133 ind./ l). When ovigerous and non-ovigerous females were presented in such high densities a significant preference was the result. (Table 1) |

The feminized males are observed at the 4th generation.
Vertical bars represent the standard deviation.
Nota: The appearnace of the intersex individuals in the culure at low temperature coincided with a decrease in food quality (Rhodomonas marina at its stationary phase). This induced a significant decrease in the mean clutch size and skewed sex ratio in favor of males. The reduction in food quality in addition to low temperature which induced slow development, are ssuspected to be responsible of the intersex individuals. This strssful situation seems to propagate to the following two generations at low temperature in contrast to the case of the experiment at higher temperature (20°C) where no intersex individual was observed |

Nota: Standing stocks estimated from the weights of each stage and their abundance varied between 0.7 µg m-3 found on 2nd November and 22.2 µg m -3 on 14 th May. In January the biomass was 3.4 µg m-3.
Production rates varied seasonally, the lowest rate (0.051 µg m3 d-1 occurring in January. In May, values of 0.405 and 0.612 µg m-3 d-1 were estimated and rates of 0.064 and 0.076 µg m-3 d-1 were found in October and November, respectively.
Despite the fact that the younger stages moulted faster than older, the greater abundance and larger increase in weight per moult of older stages resulted in greater productivity of the CIII to CV stages in January. |

Eurytemora affinis from the Bristol Channel. Abundance as a function of carnivore abundance for separte hauls made in January, Mayb and October.
Line is fitted by eye.
Nota: predation is a factor influencing the Eurytemora affinis population [as all other copepods]. Several predator species were found in the plankton hauls carried out to estimate copepod abundance [the highter difficulty is to estimate the mortality rate by natural death and local predation for the different stages during the life cycle of the species]
There was an inverse relationship between the abundance of E. affinis and carnivore abundance, suggesting that predation influences the abundance of this copepod [as all other pelagic copepods; for instance in the Banyuls' Bay,. such a lot of chaetognathes leads to a drastic reduction in the copepods' population, but localement]. In January, the commonest planktonic group capable of taking E. affinis are mysids. In May, decapods such as Crangon crangon and another formed the largest component capable of consuming copepods.. Chaetognaths dominated the carnivorous component of the plankton in October. Also, fishes are predators. |

Production estimation and Length-Weight relationship calculated for Eurytemora affinis from the Bristol Channel.
Nota: The mean abundance varied seasonally, ranging from 0.24 m-3 in november to 4.83 m-3 in May. There are considerable variation in abundance between tows, indicating that the copepod is not distributed evenly in the estuary.
In January, the population density had risen to 1.41 m-3.
It is pertinent that naupliar stages were found in January indicating that the population was reproducing; this contrast with oceanic species that typically over-winter at late copepodites stages, deferring reproduction until spring. |

Fig.6 (below): Production estimates obtained using the biomass showed above and the Polishchuk (1990) formula.
Nota: The in situ biomass evolution is characteristic for this species and can be divided in 3 phases: Winter emergence, Spring peak, Summer disappearance. Such pattern is supposed originated from a composition of internal dynamics (temperature controlled) and external control (predation, competition) (Bradley, 1975).
Combining this data set with the culture results (temperature controlled stage specific growth rates) one is able to estimate the production realized by the natural production (formulae in Ecological data methods).
The production realized by the adults (including the reproductive effort) represented 50% of the total production.
The daily production was estimated by 5 mg m3 day-1 and the annual integrated production by 1.6 mg. m3.

Whereas the biomass differed in the different areas, the P/B values showed remarkably close values. This converged with the similarirties observede for the development rates obtained in cultures supplied either with natural particulate matter or with algal cultures. Both these observations underlinede the ethophysiologic plasticity of the estuarine species. |

In culture (Katona, 1970): at 2°C: F= 1.778 mm ± 0.064; M= 1.498 mm ±0.044; at 20°C: F= 1.248 mm ±0.121; M= 1.154 mm ±0.016; between 10° and 20°C length was relatively constant and not significantly affected by different salinities from 8 to 35 p.1000.
After Kos (1976) the body length for E. hirundoides is 1.0-1.56 mm (females) and 0.9-1.15 mm (males). | | | | Rem.: | dulçaquicole, saumâtre. Tous les auteurs ne sont pas en accord sur la synonymie entre cette espèce et E. hirundoides.
