  • Sexual Maturation and Reproductive Cycle of Eledone Massyae, Voss 1964 (Cephalopoda: Octopodidae) in Southern Brazil
    BULLETIN OF MARINE SCIENCE, 49(1-2): 270-279, 1991 SEXUAL MATURATION AND REPRODUCTIVE CYCLE OF ELEDONE MASSYAE, VOSS 1964 (CEPHALOPODA: OCTOPODIDAE) IN SOUTHERN BRAZIL Jose Angel Alvarez Perez and Manuel Haimovici ABSTRACT E/edone massyae is a small benthic octopus found along Argentina and Southern Brazil. Maturation and reproductive cycle were studied based on 226 females and III males that were caught at different times of the year with trawl nets on the shelf and upper slope off Rio Grande do Sui, between 3D· and 34OS. Females started to mature in the spring and attained advanced stages in the summer at a wide range of sizes. Neither fully mature nor spent females were found. Spawning is likely to take place during late summer on rough bottoms, at some distance from the trawling areas. Spermatangia were found within the ovary of maturing females mainly in spring. Fecundity ranged from 27 to 126, with a mean of 79, and was not influenced by female body size. Male maturation started in autumn at smaller body sizes than in females. Spermatophores were found in the spermatophoric sac from the end of autumn onwards, and the most advanced gonadal stages occurred in January. Mating seems to occur principally in spring. Eledone massyae is a small octopod with a known distribution ranging from southern Argentina to Rio de Janeiro (Voss, 1964). The species was first recorded in Brazilian waters by Massy (1916) as Moschites brevis Massy, 1916, then re- described as Eledone massyae by Voss (1964). In southern Brazil, this species was caught in bottom trawls on the continental shelf and upper slope between 40 and 350 m {Haimovici and Andriguetto, 1986; Perez and Haimovici, MS)I, frequently together with a congeneric species Eledone gaucha Haimovici, 1988.

  • Cephalopoda: Octopodidae)
    BULLETIN OF MARINE SCIENCE. 56(3): 752-766, 1995 DESCRIPTIVE ECOLOGY OF TWO SOUTH AMERICAN ELEDONIDS (CEPHALOPODA: OCTOPODIDAE) J. Angel A. Perez and M. Haimovici ABSTRACT Eledone massyae and Eledone gaucha are small octopods that coexist along the continental shelf and slope of southern Brazil. A comparative study of the population structure, distri- bution and diet of these species was carried out based on bottom trawl material from fishing surveys off Rio Cirande do Sui State (Brazil), between 30043'S and 33°45'S and the isobaths of 10 and I 10m. The two species occurred throughout the year in trawls deeper than 40 m, on both sandy and muddy bottoms of the outer continental shelf and upper slope. E. massyae and E, gaucha were found at bottom temperatures ranging from 10 to 22°C in tropical, subtropical and s'.lbantarctic waters. Young E. massyae appear on the continental shelf in late summer and feed predominantly on small crustaceans such as amphipods. A single cohort of maturing animals remains on the shelf during winter and spring, switching their diet to larger prey, such as portunid crabs and polychaetes. In late summer, males and females migrate to spawning grounds outside the study area. Juveniles of E. gaucha occur on the shelf mainly during summer and autumn. Males and females seem to mature on the shelf throughout the year, although no true cohorts could be defined. In all size e1asses, small benthic crustaceans, such as amphipods and isopods are the predominant food items. There is no evidence of habitat segregation between these two eledonids, but as adults, they seem to exploit different food resources, Cold-water octopods constitute over half of the total number of benthic Octo- poda species reported from the southern Brazilian coast (Haimovici and Perez, ]99] b).

Bottom trawling is important in Brazilian fisheries and is currently highly multi-specific due to the overexploitation of the original targets; unselective fishing method; very large permitted fishing area and the country’s high marine biodiversity. Fishing licensing in Brazil was modified in 2012 and is now based in five criteria: target species; “expected by-catch”; “incidental catches”; fishing method and area of operation.

  • Determination of Mean Level of Argentine Sea
    DETERMINATION OF MEAN LEVEL OF ARGENTINE SEA Influences of Oscillations of the Sea not Caused by the Tide by Marciano A . BALAY, Chief, Tidal Division Note by Directing Committee of I.H .B. : The « Argentine Sea » mentioned in the following article is stated to include : « The whole of the continental shelf from the shore to the slope determined by the Argentine Atlantic Trench in the East and Drake Passage in the South ». This area has not however been listed in the Bureau’s Special Publication No. 23 « Limits of Oceans and Seas », nor has the name « Argentine Atlantic Trench » been so far adopted by the International Committee on Ocean Bottom Features. Introduction. Mean sea level is defined in principle as the surface where the tide is zero, and is determined by integration of the tide curve. Integration of the tide curve -may be accomplished mechanically and simultaneously by recording the tide by means of an « integrating tide-gauge », or by computation, i.e. by determining the arithmetical mean of hourly heights of the tide, previously obtained over an extensive observational period. The tide curve, however, is not only the graphical expression of oscillations in sea-level due to lunisolar action, since it likewise totalizes all the effects of disturbing agents unrelated to the tide proper, and principally the action of the enveloping atmosphere. Integration of the recorded tide curve will therefore not represent the « zero-tide surface », since the character of random action cannot be attributed with accuracy to influences of factors unrelated to the tide, even when a long series of observations is analysed.
