“…Hence, it can be suggested that along with all the conditions mentioned above, moulting is essential to the onset of the reproductive period in females, as has been observed for most lobsters (MacDiarmid & Sainte-Marie, 2006).

The reproductive biology of Scyllarides deceptor was studied along the southern Brazilian coast (278S 488W) from December 2002 to December 2003. Samples were collected monthly at Xavier Island, where animals were caught and marked. Fecundity and egg size were estimated from ovigerous females caught also in two adjacent islands, Arvoredo and Aranhas. A total of 98 females was recorded at Xavier Island during the sampling period, 24 of these were recaptured and presented time-at-liberty ranging from 14 to 297 days. Ovigerous females were observed during spring and summer, with the moulting period lasting from late winter to spring. Size at sexual maturity was assessed from 66 females caught during the breeding season and estimated in 85.33 mm of carapace length (CL). Mean fecundity of S. deceptor was estimated in 191,262 eggs (+17,811, SE) for females, on average, 94.74 mm long (+1.86 mm SE) (CL). Fecundity was significantly related to CL (R 2 ¼ 0.90) Mean egg size was 0.67 mm (+0.005 mm SE) and did not correlate significantly to CL (P ¼ 0.78). The rocky bottom of Xavier Island was favourable for reproduction, presenting shelter and foraging grounds for the ovigerous females. For management purposes, our results suggest the closure of the S. deceptor fishery from November to January and the capture-size of females to be restricted to animals larger than 90 mm (CL).

“…Such management measures (spawning sanctuaries and maximum size limits) would facilitate conservation and help control fishing effort, but are not risk free: catch and effort (e.g., bottom gillnets) might be relocated to other fishing zones causing worse impacts than the benefits gained from the establishment of the spawner sanctuary. However, in Brazil, the implementation of such spatial management tools and their design criteria (e.g., location, area and lobster size) is likely to be effective for the following reasons: (i) each spawner sanctuary should be large enough to mitigate the recruitment overfishing problem and must be capable of increasing fecundity and larval export, with an increasing number of pueruli migrating inshore by way of current retroflection in the Western Atlantic (Cruz et al, 2011) thereby ensuring successful annual self-recruitment; (ii) abstaining from catching larger lobsters can increase egg production and the overall quality of the eggs in a population, resulting in larger larvae (MacDiarmid & Sainte-Marie, 2006); and (iii) the risk of re-localization of effort associated with bottom gill nets will be minimal (Cavalcante et al, 2011 ;Cavalcante & Neto, 2014) as the authorities are working to eliminate the use of this illegal gear to protect the benthic ecosystem (Paiva et al, 1973) and lobster resources in deeper waters.…”

A B STR A C T T he spiny lobster Panulirus argus (L atreille, 1804) is the m ost im portant com m ercial fishing resource in the w estern c entral A tlantic and Brazil. F ield studies covering the w aters o ff southw estern C uba and northern B razil have im proved our understanding o f th e variations in the reproductive potential (num ber o f eggs), stock recruitm ent and reproductive efficiency o f spiny lobsters according to location, depth and size class. U sing the spaw ner-recruitm ent m odel, the reproductive potential index w as correlated w ith the index o f subsequent recruitm ent based on field sam pling. Spiny lobster habitats in deeper w aters need special attention in order to p rotect the species from overfishing o f the recruitm ent. C onsidering the longevity and absence o f reproductive senility in spiny lobsters, m anagem ent strategies should ideally include the creation o f spaw ner sanctuaries (m arine protected areas) capable o f restoring and m aintaining the biom ass o f the spaw ning stock and the establishm ent o f a m axim um catch size o f 135 m m (CL) fo r both sexes along the entire B razilian coast. B ased on our findings, w e propose to establish spiny lobster sanctuaries (50-100 m ) on the continental shelf o ff northern B razil, from A m apâ (5°25'N 5 1°0'W ) to the w estern reaches o f the co ast o f P ara (1°1 l 'N 46°27/W, 0°42rN 46°45,W ), covering a total surface area o f 64 230 km 2 . R E SU M O A lagosta e spinhosa Panulirus argus (L atreille, 1804) é o recurso p esqueiro de m aior im portância com ercial do A tlântico centro-oeste e Brasil. E studos de cam po, em âguas do sudoeste de C uba e norte do B rasil, têm m elhorado a com preensào das variaçôes do potencial reprodutivo (abundância de 4 1316 RAÜL CRUZ ET AL.ovos), estoque-recrutamento e eficiência reprodutiva de lagostas com relaçâo à localizaçào, profundidade e tamanho de classe. Com base em amostragens de campo e utilizando modelo recrutamentodesova, o indice de potencial reprodutivo foi correlacionado corn o indice de recrutamento subsé quente. Os habitats de lagosta em âguas profundas necessitam de atençào especial visando à proteçào da espécie da sobrepesca por recrutamento. Considerando a longevidade e a ausência de senilidade reprodutiva em lagostas, estratégias de gestâo devem incluir a criaçâo de santuârios (area marinha protegida) para desova, capazes de restaurar e manter a biomassa da populaçào reprodutora e o estabelecimento de um tamanho mâximo de captura de 135 mm (CL) para ambos os sexos, para toda a costa do Brasil. Os resultados permitem propor um santuârio (area marinha protegida) da lagosta (50-100 m) ao longo da plataforma continental norte do Brasil, do Amapâ (5°25'N 5°0'W) até a costa oeste de Para (1°1 l^N 46°27,W, 0°42,N 46°45,W), cobrindo uma area superficial total de 64 230 km2.

“…Giri & Wicksten, 2001. Female Sclerocrangon boreas (Phipps, 1774) (Crangonidae) are more likely than males to be fouled by the barnacle Balanus balanus (Linnaeus, 1758) due to their slower molting rate (Sainte-Marie et al, 2006). Bauer (1979) and Felgenhaur & Schram (1979) demonstrated the importance of grooming in removal of fouling ciliates, algae, and bacterial chains on the appendages of carideans.…”

“…Ovaries are then connected to the genital aperture at the coxa of the third pereiopod via a short duct. The testes give rise to long, convoluted vasa deferentia that lead to gonopores at the coxa of the fifth pereiopods in males MacDiarmid & Sainte-Marie, 2006). The vasa deferentia are divided into three sections: proximal, mid, and distal (Paterson, 1969;Silberbauer, 1971).…”

“…68.22;George, 2005). This penile process may aid in directing spermatophore placement, detecting deposited spermatophores, or removing previously deposited spermatophores (MacDiarmid & Sainte-Marie, 2006). There is some evidence that small males may pass less ejaculate to females than large males Mauger, 2001) resulting in smaller clutches carried by females .…”
