“…Gonadal criteria (or physiological maturity) are also a potential indicator of size at maturity, and have been associated with allometric changes in abdomen width as the female crab matures (KNUDSEN 1960, HARTNOLL 1974, 1982, HAEFNER 1990. Therefore, the use of more than one method to determine size at maturity appears to be appropriate, particularly if these methods are to be used to stipulate the minimum legal size of commercially exploited species (HAEFNER 1990, ALUNNO-BRUSCIA & SAINTE-MARIE 1998, OVERTON & MACINTOSH 2002.…”

“…For many brachyuran species, morphological changes in the female abdomen may occur abruptly (after the molt to puberty) or may take place progressively, after several molts (HARTNOLL 1974(HARTNOLL , 1982. In grapsoid crabs these abdominal changes are not obvious and the abdomen widths of mature and immature females overlap, which makes it difficult to determine the onset of maturity by means of morphometric methods (HARTNOLL 1965).…”

ABSTRACT. The aim of the present study was to ascertain the size at sexual maturity in females of the crab Sesarma rectum Randall, 1840 by comparing gonadal maturity to morphologic maturity (using abdomen-width data). The relative growth of the abdomen was analysed for all growth phases (for each 3-mm carapace width size class), and the slopes of the separate allometric relationships were compared through analysis of covariance (ANCOVA) from log e -transformed data to detect changes in the level of allometry during ontogeny. The physiological size at maturity (gonadal criteria) was determined through a logistic curve, indicating the size at which 50% of females presented mature gonads (M 50 = 17.4 mm CW). The highest allometric levels occurred in growth phases 2 and 3 (body sizes ranging from 15 to 21 mm CW), indicating faster growth of the abdomen during those phases. Phases 1 (< 15 mm CW) and 4 and 5 (size classes above 21 mm CW) showed isometric growth. In the study area, a mangrove on the northern coast of the state of São Paulo, Brazil, individuals of S. rectum began to reach sexual maturity from 15 mm CW onward, when the slopes of the relationship of abdomen width to carapace width became positively allometric, indicating a differential growth rate. A gradual decrease in the slope, tending to isometry, occurred during ontogeny, as the animals became larger (older).

“…After the introduction of histological and image analysis methods, the suitability of lipofuscin accumulation for ageing has been widely recognized, especially in crustaceans, which loose all durable hard parts during the moult (HARTNOLL, 2001).…”

“…Moreover, the trend in the most recent research into red shrimps is to assign them a longer life span, and obviously slower growth and lower natural mortality rates, than previously believed (CAU et al, 2002). In the search for more precise aging methods for crustaceans, the classic alternatives are rearing and tagging, whenever they are feasible; novel methods involve radionuclide ratios, examination of the ovoid bodies and lipofuscin accumulation (HARTNOLL, 2001).…”

“…The 'ovoid body', a durable hard structure in the stomach, has been so far observed only in Norway lobsters (HARTNOLL, 2001). Consequently, lipofuscin accumulation seems the most promising alternative method for ageing red shrimps, given its broadly demonstrated association with senescence (KATZ & ROBISON, 1986;ANONYMOUS, 2002;BRUNK and TERMAN, 2002).…”

Lipofuscin, a non-degradable, degenerative fluorescent pigment which accumulates in post-mitotic cells, represents a promising method for ageing marine crustaceans. The presence and accumulation of lipofuscin has been studied in the deep-water red shrimp Aristaeomorpha foliacea (Risso, 1827) to assess its use as a tool for ageing larger (i.e., older) specimens and thus improve knowledge of the growth and longevity of this species. Specimens, gathered during experimental trawl surveys carried out in the Strait of Sicily (Mediterranean Sea), were stored directly on-board in 10% buffered formaldehyde solution; their brain was thereafter removed, prepared with various current histological techniques and examined with a binocular microscope. Thin sections of the olfactory lobe cell mass were also analyzed using fluorescence microscopy, and the lipofuscin concentration was measured through image analysis. Various indices were computed for each individual by pooling data from many images: number and coverage of the lipofuscin granules per unit area, and mean individual area of the granules. Lipofuscin was detected in all specimens investigated with characteristics (grain typology and dimension) strictly resembling those already described in other crustacean species. The present preliminary results encourage further studies to develop and validate a methodology based on the use of lipofuscin for improving the relative ageing of large A. foliacea shrimps.
