“…The production of oocytes by males may be due to a proportion of the green Haliclona population being hermaphroditic, while other individuals within the population have a gonochoric habit. This has been reported previously (Lewandrowski & Fell 1981, Simpson 1984, Wapstra & van Soest 1987, as has the alternation between a mostly gonochoric and a mostly hermaphroditic population (Fell & Jacob 1979, Simpson 1984. However, the oocytes found in green Haliclona sponges that also produced spermatic cysts were never observed to develop into embryos, unlike hermaphroditic individuals of Halichondria sp.…”

The reproductive biology of 2 haliclonid sponges was examined over a 2 yr period. Histological samples of Haliclona sp. 1 (green Haliclona) and Haliclona sp. 2 (brown Haliclona) from tagged and haphazardly sampled individuals of both species were examined using light microscopy. Interest in these 2 sympatric species is high, due to the potent and unique bioactive compound (salicylihalamide A) they produce, hence the need to understand the reproductive biology of both species to ensure their proper conservation and management. Green Haliclona is viviparous, with both gonochoric and hermaphroditic individuals in the sponges sampled. Brown Haliclona is also viviparous and is clearly a gonochoric species. Only decreasing wave height showed a significant correlation to gametogenesis, but the onset and progression of reproduction in both species coincided with increases in water temperature and photoperiod. Oogenesis for both species extended from November to April. Spermatogenesis extended over 3 mo for green Haliclona (January to March) and 4 mo for brown Haliclona (January to April). Embryogenesis within brood chambers started in January and extended over 4 mo in green Haliclona and 5 mo in brown Haliclona. The parenchymellae larvae of green Haliclona were observed in tissue samples for 2 mo compared to 4 mo for brown Haliclona. The reproductive output of each species was similar; however, female reproductive output at 2.9% (green Haliclona) and 2.4% (brown Haliclona) of the mesohyl was much lower than that of other viviparous species. Male reproductive output (2.3 and 2.4% for green and brown Haliclona, respectively) compares favourably to that of oviparous species. The high reproductive output of males and the timing of reproduction in both species of sponge appears to help in reducing the risk of unsuccessful fertilisation and lower the probability of larvae being released into unfavourable conditions.

“…These findings are in agreement with data recorded in this species under natural conditions ( Turon, Tarjuelo & Uriz, 1998 ; Garrabou & Zabala, 2001 ), or in farming experiments involving other species ( Duckworth & Battershill, 2003b ). Seasonal growth differences have been reported for sponge typically dwelling in shallow water characterised by fluctuating conditions ( Lewandrowski & Fell, 1981 ; Barthel, 1986 ).…”

BackgroundThe marine sponge Crambe crambe was chosen as an experimental model of sustainable shallow-water mariculture in the Sardinian Sea (Western Mediterranean) to provide biomass with high potential in applied research.MethodsExplants were cultured in four long-term experiments (19 and 31 months at ca. 2.5 m depth), to determine the suitability of new culture techniques by testing substrata and seeding time (season), and monitoring survival and growth. Explants were excised and grown in an experimental plant close to the wild donor sponge population. Percentage growth rate (GR%) was measured in terms of surface cover area, and explant survival was monitored in situ by means of a digital photo camera.ResultsExplant survival was high throughout the trial, ranging from 78.57% to 92.85% on travertine tiles and from 50% to 71.42% on oyster shells. A few instances of sponge regression were observed. Explant cover area correlated positively with season on two substrata, i.e., tiles and shells. The surface cover area and GR% of explants were measured in the starting phase and monitored up to the end of the trial. High GR% values were observed both on tiles (>21%) and on oyster shells (>15%).DiscussionThe data on the behaviour and life-style of cultured fragments, together with an increase >2,400% in cover area, demonstrate that in situ aquaculture is a viable and sustainable method for the shallow-water biomass supply of Crambe crambe.

“…In Hippospongia lachne, Mycale sp., and Tetilla serica smaller sponges either do not initiate gamete development or produce few of them (Storr, 1964;Reiswig, 1973;Watanabe, 1978a). Alternatively, in Ochridaspongia rotunda and Clathrina, all sizes of animals are reproductively active (Gilbert and Hadzisce, 1977; 188.9 235.9 'Data taken from Lewandrowski and Fell (1981 (Fell, 1976b). In Ophlitaspongia seriata, Fry (1971) found that the level of gametogenesis (as indicated by larval release) can be highly variable and is not size dependent; in Suberites massa, Diaz (1979a) has reported a similar situation.…”

“…A causal link between dormancy and sexual reproduction might therefore be suggested. However, it is now also known that young sponges recently developed from larval metamorphosis also enter sexual reproduction very quickly Simpson and Gilbert, 1974;Lewandrowski and Fell, 1981) as do overwintering species (see later section) which redevelop functional canals (Simpson, 1968b;Fell and Jacob, 1979). Thus, a number of forms of active development appear possibly as stimuli for sexual reproduction with gemmule hatching as one of them (Simpson, 1980).…”

PrefaceThe writing of this work was stimulated by discussions with colleagues in the fields of biochemistry, developmental biology, and physiology who expressed their, and other's, need for a current, critical review and analysis of sponge cell biology, and secondly by my own conviction that the field of sponge biology in general could benefit from such a synthesis and evaluation of the data. The major problem faced in writing this book was that of balancing the text relative to presenting, on the one hand, a review of the data and, on the other hand, a synthesis of it. A vigorous attempt has been made to be as uniform as possible in reviewing data but this, of course, is not always possible because some papers stand out as key advances in one or more areas. To the extent that it has been feasible to synthesize specific perspectives or to emphasize deficiencies in knowledge, these have been done. A major effort is made to review cellular structure per se since this has not previously been attempted. Some speculations are also to be found and these, hopefully, will not only stimulate new investigations but will also serve as respites from the unavoidable rigidity of data review. Much effort has been expended to avoid errors, although it is probably not possible in an undertaking of this scope to finally arrive at an error-free state. For such of those that do occur by omission or otherwise, I take full and sole responsibility.There are a number of important, recent monographs and symposial volumes which contain much information on sponge cell biology as well as other topics. Outstanding among them is Biologie des Spongiaires (C. Levi and N. Boury-Esnault, Eds., 1979. Editions de CNRS, Paris).
