On the Sexual Biology of Pandalus Borealis ( Crustacea Decapoda )

On the Sexual Biology of Pandalus Borealis (crustacea Decapoda) Iii. the Initiation of the Female Phase by D. B. Carlisle

In the second paper of this series (Carlisle, 1959b) I have described the results of various experimental manipulations upon the termination of the male phase in the protandric hermaphrodite Pandalus borealis Kmyer. In this paper I shall be concerned with the effects of such interference upon the initiation of the female phase of the life history. In a number of papers Panouse (1943-8) provided...

Aspects of biology of Atya gabonensis (Giebel, 1875) (Crustacea: Decapoda: Natantia) at the confluence of river Niger and Benue, Ganaja, Kogi State, Nigeria

Aspects of biology of Gabon prawn, Atya gabonensis (Giebel, 1875) was investigated in the confluence of River Niger and Benue, North-Central Nigeria. A total of 2,175 specimens were collected from January to December, 2017 by fishermen using combination of gears (drag nets, set traps and traditional gear known as “Ahina”) and transported in icebox containing water to the laboratory for further ...

Low richness of hermit crabs community (Crustacea: Decapoda: Paguroidea) and high dominance of Clibanarius signatus in the intertidal zones of Larak Island, Persian Gulf, Iran

Abstract Hermit crabs community in the intertidal zones of Larak Island were investigated through a seasonal sampling at five stations using random quadrate sampling method. Overall, seven species were identified and Clibanarius signatus was the dominant species, which showed high dominance over other species. Using Bray-Curtis cluster analysis for comparing seasonal abundance showed that exce...

Short Communication:A subtidal porcellanid crab, Petrolisthes militaris (Heller, 1862) (Crustacea: Decapoda: Anomura), from the Persian Gulf, Iran

A snap shot of the short-term response of crustaceans to macrophyte detritus in the deep Oslofjord

A test deployment of a time-lapse camera lander in the deep Oslofjord (431 m) was used to obtain initial information on the response of benthic fauna to macroalgal debris. Three macroalgal species were used on the lander baited plate: Fucus serratus, Saccharina latissima and Laminaria hyperborea and observed during 41.5 hours. The deep-water shrimp Pandalus borealis were attracted to the macroa...
