... The giant red shrimp, Aristaeomorpha foliacea (Risso, 1827), is a species with a wide spatial distribution. It can be found in the eastern and western Atlantic, the western Pacific, the Indian Ocean, and along the South African coast, as well as in the Mediterranean Sea (Ragonese et al., 1997;Bianchini, 1999;Kao et al., 1999;Dall, 2001;Guillen et al., 2012;Hernandez, 2012;Perdichizzi et al., 2012;Fernandez et al., 2013;Guijarro et al., 2019). A. foliacea is a deep-water benthopelagic shrimp species that aggregates in submarine trenches and canyons (D'Onghia et al., 1998) and is usually found near muddy bottoms from 150 m to 1350 m with a peak abundance between 500 m and 700 m (Fischer et al., 1987;Ragonese et al., 1997;Bianchini, 1999;Politou et al., 2004;Bayhan et al., 2015). ...

It shows a characteristic sexual dimorphism; females reach larger sizes than males, and males are sexually mature at a smaller size than females (Kapiris, 2005;Ragonese et al., 2011). ...
The main aim of this study was to contribute to the current knowledge on the population of Aristaeomorpha foliacea in Antalya Bay located on the southern coast of Turkey in the Mediterranean Sea. Monthly samples were collected between July 2016 and July 2017 from experimental trawl surveys in accordance with the International Bottom Trawl Survey in the Mediterranean (MEDITS) protocol. The abundance index was calculated as 4308.6 N/km^2 and the biomass index as 66.8 kg/km2. The relationship between total weight (TW) and carapace length (CL) was estimated to be TW = 0.00078·CL^2.76 for females and TW=0.00049·CL^2.92 for males. The seasonalized von Bertalanffy growth parameter estimates were CL∞ = 66.12 mm, K = 0.43 years^-1, tanchor = 0.36 years, C = 0.63 and ts = 0.21 years for females, and CL∞ = 44.02 mm K = 0.39 year^−1, tanchor = 0.30 years, C = 0.77 and ts = 0.87 years for males. Female shrimps grew slightly faster and reached a larger asymptotic size hence exhibiting a greater growth performance than males. The spawning season was determined as the summer. Recruitment took place in spring, and the sex ratios were found to be 1.29:1 in favor of males. The median size at first maturity was estimated as 37.7 mm CL for females and 30.1 mm CL for males. The annual total mortality rate was 1.66 and 1.41, the annual natural mortality rate 0.57 and 0.72, and the exploitation rate 0.66 and 0.49 for females and males, respectively. The fishing ground for A. foliacea in Antalya Bay is situated within 12 nautical miles off the shore within the territorial waters, thus closed to commercial trawl fisheries between 15 April and 15 September in accordance with the Turkish fishery regulations. The closing period, which coincides with the spawning season and also provides a reduction in the fishing pressure, is clearly of great importance for the sustainability of this species in Antalya Bay.
... The giant red shrimp Aristaeomorpha foliacea (Risso 1827) belongs to the family Aristeidae, which includes other important species such as the blue and red shrimps (Aristeus antennatus Risso 1816) and scarlet shrimp (Plesiopenaeus edwarsianus Johnson 1868) [1]. A. foliacea is widely distributed in the eastern and western Atlantic, Indian Ocean, and western Pacific, in the waters of Japan, Austalia, New Zealand, and in the Mediterranean Sea. ...
Heavy metal concentrations (Cd, Pb, Cu, Zn, Fe) in the muscle and liver of female and male specimens of economically significant giant red shrimp (Aristaeomorpha foliacea) taken from the Mediterranean Sea were determined in this study. Samples of species were collected in summer and winter. The results show that the concentrations of heavy metals in liver for male and female shrimps were higher than those in muscle. Also, the average Cd, Pb, Cu, Zn, and Fe concentrations in both liver and muscle for male shrimp were slightly higher than the average levels of female shrimp. Significant differences were observed only for Cu in liver and for Fe in muscle (p<0.05). When our findings were compared to international standards, it was discovered that the quantities of Cd, Pb, Cu, Zn, and Fe in muscle tissue were lower than the recognised range of WHO and FDA criteria.
... Morphometrics and length-weight relationships are widely used in fisheries. Especially, they have been used to study population characteristics and the stock assessment of commercially important species [9,15]. Though crab specimens used in the study represented all maturity stages in the life cycle of the blue swimming crab and were considered in the study for developing morphometric relationships, the occurrence of different growth rates between distinct parts or organs of the body are possible [5]. ...
The blue swimming crab (Portunus pelagicus) has become the focus of an important export-oriented fishery in Sri Lanka for a decade. The Palk Bay in the Northern coastal waters of Sri Lanka is one of the best-known fishing grounds for blue swimming crabs in Sri Lanka. This study was undertaken with the aim of establishing some morphometric relationships for P. pelagicus in the Palk Bay. Biological sampling was conducted for five consecutive days per month from November 2014 - October 2015 in the Northern landing sites in the Jaffna District where the catch of Palk Bay blue swimming crab fishery was landed. P. pelagicus specimens were also randomly collected for laboratory analysis. The morphometric measurements of the specimens for the following parameters were undertaken: CW - carapace width with the spine, CWW - carapace width without spine, MW – mouth width, TL - total length, LCPL - left chelar propodus length, LMOV - left movable part Length, RMOV - right movable part length, LCPH - left chelar propodus height, RCPH - right chelar propodus height, ABW - abdominal width, ABL - abdominal length and BW - body weight. The least squared method was used to obtain the Length-Length (L-L) and Length-Weight (L-W) relationships. Of the 65 L-L relationships obtained for P. pelagicus from the study, 34 relationships were correlated (r2>0.5). The estimated relationships between BW and CW for males and females were BW=0.0001 CW 3.01 (r2 =0.84) and BW= 0.0001 CW 2.90 (r2 =0.86), respectively. Positive allometric growth was observed for male P. pelagicus, whereas a negative allometric growth was observed for female P. pelagicus. Most of the morphometric relationships of P. pelagicus obtained in this study were not isometric.

By combining the current yields (in the order of several thousands tons by year) and the corresponding high unit values (up 80, for the 1st grade specimens, and 200 euro /kg during holydays), Aristeus antennatus (Risso, 1816), herein VP, and Aristaeomorpha foliacea (Risso, 1827), herein RP, likely represent the most valuable demersal stocks for the Mediterranean bottom trawl fisheries. These species (herein Reds) have also acctracted the interest and attention of many researchers, not only among the fisheries biologists, but also among scientists involved in genetic and climatic studies. Countless publications have been recently realized within both the official (i.e. ISI Journals) and gray (i.e. technical and internal / project reports) scientific literature. In spite of the impressive improvement in the knowledge level concerning Reds, the scientific name to be used, the lack of cryptic species (at least within the Mediterranean Sea), and the negligible (almost null) estimated gross catch fraction returned to the sea (a.k.a. discard), likely represent the only items about which scientists fully agree. Controversies range from the simple choice of the most pertinent colloquial name (Blue and red shrimp, Blue shrimp, Giant red shrimp, King shrimp, Bathyal shrimp, Deep water red shrimp, Red shrimp, Rose shrimp, Pink shrimp, Violet shrimp, Red prawns etc) to the more critical choice between few widespread geographical instead of many small scattered stock (stocklet). Actually, whichever the Reds life history trait is considered, the pertinent literature show uncertainty at least with the past (for example, e.g., the reported life span from 3-5 up 9-12 years), conflicts in the interpretations (“clear evident unidirectional”, “parabolic concave down” or “not at all” depth - size relationship), contrasting sentences (discrete vs continuous spawning, recruitment, nurseries areas), confusion about the most influent abiotic parameters (LIW i.e. Levantine Intermediate Seawater temperature and salinity, “cascade” effects or even the damming of the Nile river). No clear and universal proofs of the validity of the various proposed explanatory variables (e.g. the strong association with the bamboo coral Isidella elongata) can be currently found. The most critical item in Reds studies is represented by the “single compartment syndrome”, i.e. each (or few) biological parameter(s) is/are discussed without any critical consideration about the match-mismatch with all the other parameters available. For example, in both Reds, females are almost universally considered more robust and better growth performant than males, reaching a much larger size and living longer than males. Both sexes occur in the same (RP) or different (VP) depth interval; consequently, females should be expected to suffer a lower (RP) and higher (VP) total mortality (Z) than males in exploited stock. However, the overall current sex ratio is reported as balanced or even in favor of males in RP and females in VP, without any specific comments about the different effects of fishing mortality. In the present contribution, papers and reports published between 1885 and 2018, directly or indirectly related to Reds, were reviewed in order to attempt a synoptic comparison of the gray sides in the level of agreement about the distribution and life cycle of such as important crustaceans. The outputs of the present review were organized in 3 sections: A) Introduction, B) Material, methods (and some remarks), and C) 19 basic questions (such as “How many Reds’ poulations within the Mediterranean Sea?”). The corresponding answers were presented as Thesis, Antithesis and (most plausible) Synthesis. Finally, in the last section (D – Bibliography), the interested reader will be able to find an exstended list of references, considering not only the titles quoted in the contribution.
... Furthermore, biometric studies are useful in ecological studies since populations of the same species may exhibit morphological differences that reflect adaptations to the local environmental conditions (Debuse et al. 2001;Brash et al. 2017) [30,31] . The species is far from well-studied in Greek waters and east Mediterranean Sea, with only two published studies being available (Kapiris et al. 2015;Erdoğan Sağlam et al. 2018) [32,33] . Kapiris et al. (2015) [32] presents some relative preliminary data from Greece and highlights the necessity for further research like ours. ...

Although, that the abdomen growth pattern seems to be distinct in mantis shrimps (Antony et al. 2014) [19] [8,32] or the sampling methodology (trawlers, Vila et al. 2013, Kapiris et al. 2015 [8,32] . Remarkably, the present data are in contrast with the study of Erdoğan Sağlam et al. [33] , where the sampling size is similar n= 936 and the sampling methodology involved the use of nets. Males demonstrated a negative allometric growth pattern and is in accordance with all abovementioned studies. ...
The length-weight relationships (L-W) and the allometric growth profile of the stomatopod Squilla mantis was studied from Thermaikos Gulf, Aegean Sea, Greece. In total, 756 individuals were collected, by artisanal net fishery and log transformed data were used at the (L-W) relationships assessment. Three body parts were measured [carapace length (CL), abdominal length (ABL), and telson width (TW)]. Both females and males demonstrated similarities at their allometric profiles except for CL-W, where females present positive allometric profile and males negative. The present findings are mostly in accordance with earlier studies from Mediterranean.

Os pressupostos da análise de regressão, ou seja, o padrão de normalidade da distribuição dos resíduos, a homogeneidade de variâncias e a independência dos dados, foram validados por meio de gráficos de resíduos e resíduos padronizados versus valores previstos e por meio de gráficos de probabilidades normais (Ragonese et al., 1987;Crawler, 2007;Venables & Simth, 2008;Ogle, 2009). ...
No presente trabalho foram estimadas relações biométricas entre algumas medidas de comprimento e peso do corpo do camarão rosa Penaeus subtilis (Pérez Farfante, 1967) na plataforma continental amazônica. Foram utilizados dados de amostras obtidas a bordo de navio de pesquisa, bem como amostras obtidas por ocasião de desembarques nas empresas de pesca em Belém, estado do Pará, no período de 1995 a 1998. Para ajuste das equações foram utilizadas as técnicas de regressão linear e não linear baseadas nos métodos dos mínimos quadrados e máxima verossimilhança, respectivamente. Foram calculadas regressões para fêmeas e machos, considerando os dados de todo o período do estudo, agrupados numa base trimestral e anual. Verificou-se que as fêmeas crescem mais que os machos e, assim, as curvas das várias regressões para machos e fêmeas apresentaram diferenças significativas. Foram encontradas também diferenças expressivas entre os parâmetros aqui calculados e os parâmetros apresentados por outros autores em trabalhos anteriores. Os valores do fator de condição foram sempre superiores para os indivíduos maiores, sugerindo presença de indivíduos maduros ao longo de todo o ano, mas em menor proporção no primeiro trimestre.

The same pattern is also well known for Aristaemorpha foliacea (Risso, 1827) (Ragonese et al., 1997), Aristeus antennatus (Risso, 1816) (Carbonell et al., 1999) and Heterocarpus laevigatus (Dailey and Ralston, 1986). This pattern results in higher mobility thus providing an advantage in predation in highly specialized active predators of macroplanktonic species as stated by Cartes (1993). ...
Length and weight relationships and descriptive statistics are reported for six shrimp species caught off the Madeira archipelago between 1983 and 2014 using bottom and floating traps from depths ranging from 50 to 1,300 m. The parameter b ranged between 2.36 for Plesionika ensis and 2.97 for Plesionika williamsi. All species showed a pattern of negative allometric growth. To the authors’ knowledge all weight-length relationships presented herein are recorded for the first time from the Madeira area, and in the cases of Ligur ensiferus and Plesionika ensis are the first references worldwide.
... The geographically widespread giant red shrimp, A. foliacea, is one of the most important exploited crustaceans, having a long traditional and economical significance for the deep fishery of the western and central Mediterranean (Papaconstantinou & Kapiris, 2003). It occurs along the continental slope from 150 m to 1850 m with a peak in abundance between 300 m and 700 m, showing a preference for muddy bottoms, with aggregations mainly in submarine trenches and canyons (Ragonese et al., 1997). The species was rarely recorded in the eastern Mediterranean probably due to a lack of studies implemented in those areas and its stocks are considered pristine in some areas as its exploitation has not yet been developed (Papaconstantinou & Kapiris, 2003;Gönülal et al., 2010). ...
The aim of this study was to contribute to a better knowledge of demersal species in the Lebanese coastal waters, Eastern Mediterranean. Various aspect related to the distribution, diversity and biology of these species were studied. The data were collected from a three-year experimental survey in the framework of the ‘CIHEAM-PESCA Libano project’. A highly diversified mix of fish species (teleosteans and selaceans), cephalopods and crustaceans were sampled. Spatio-temporal distribution and diversity was evaluated respectively using the ‘Catch Per Unit Effort’ which was considered as an approximation of an abundance index and the total number of species caught in the surveys.
... Especially, in shrimps or prawns, several researches deal with morphometric analysis and allometric growth (e.g. Ragonese et al., 1997;Mossolin and Bueno, 2003;Mariappan and Balasundaram, 2004;Deniz (Bök) et al., 2010, 2013Konan et al., 2010). In the present study, descriptive statistic values of characters for males and females of M. macrobrachion are presented separately. ...
The present study describes the length-weight relationship (LWR), length-length
relationship (LLR) and condition factor of the wild population of the shrimp
Macrobrachium macrobrachion from the rivers of Côte d’Ivoire (West Africa).
Samples were randomly collected from small-scale shrimp fisheries using bamboo
traps. Of the thirteen analyzed morphometrics characters, only the second pleura width
significantly varies between males (13.11 mm) and females (14.78 mm). All
relationships between the considered variables were significantly linear, r2
ranging from
0.66 to 0.97. For length-length relationships, the allometry coefficient varied depending
on groups, environments and characters, and ranged between 0.64 and 1.26. The three
allometry types (negative allometry, isometry and positive allometry) were observed in
this relation. In length-weight relationship, the coefficient ranged from 2.02 to 2.78,
indicating a negative allometry. The condition factor values showed that females
(0.70±0.06) were in better condition than males (0.657±0.07). Overall, the condition
factor followed an east-west gradient, decreasing from eastern (0.70) to western (0.63)
regions. These results constituted an important biological database on M.
macrobrachion from the rivers of Côte d’Ivoire for further studies as ecology,
reproductive biology, and aquaculture potentialities of this species.

This study was carried out to detect the concentration of fatty acid in female and male specimens of commercially important giant red shrimp (Aristaeomorpha foliacea) obtained from (including 20 male shrimps and also 20 female shrimp) Mediterranean Sea. In fatty acid composition, the saturated fatty acid fraction was dominant, followed by polyunsaturated fatty acid and monounsaturated fatty acid for both sexes. The analyses indicated that PUFAs, and the MUFAs content were higher in female shrimp than in those of males and they were statistically significant differences in fatty acid profile between females and males (p<0.05).
