Kinds, Distributions and Abundances of Sea Bass Larvae (Pisces: Serranidae) from the Eastern Gulf of Mexico BULLETIN OF MARINE SCIENCE, 32(2): 511-522, 1982 KINDS, DISTRIBUTIONS AND ABUNDANCES OF SEA BASS LARVAE (PISCES: SERRANIDAE) FROM THE EASTERN GULF OF MEXICO Edward D. Houde ABSTRACT Occurrences, distributions and abundances of serranid larvae from the eastern Gulf of Mexico were described based on 505-lLmmesh bongo net collections made during 13 cruises in 1971-73. A diverse assemblage of serranid larvae was collected, totalling 5,350 individuals. Four subfamilies were represented and 11 genera and 14 species (or types) were identified. The most abundant serranid larva was Diplectrum formosum, followed by Hemanthias vi- vanus. Larvae of D. formosum were the fifth most common species of all fish larvae that were collected on the cruises and accounted for 55.5% of the serranids. Other common serranid larvae included Serraniculus pumilio, Centropristis ~'triata, Pronotogrammus au- reorubens, Anthias Type I, epinepheline larvae and Rypticus spp. Larvae of serranids were collected over the entire shelf area in the eastern Gulf during all seasons, but species that occurred differed by area, season and depth zone. Apparent differences in annual mean abundances were observed for some species. Relationships between occurrences and surface temperature and salinity were examined. Spawning seasons were inferred from the larval occurrence data. The sea basses (Serranidae) are a diverse group of perciform fishes that are well represented in tropical and temperate oceans of the world, with many species important to commercial and recreational fisheries. Spawning areas and seasons of serranids were poorly known in the eastern Gulf of Mexico. The objectives of this paper are to report the kinds and abundances of serranid larvae in the eastern Gulf as well as seasons and areas where they occur. Delineating distributions of pelagic larvae by area and time allows inferences to be made about adult distri- butions, spawning areas and spawning seasons. Larvae of most serranid species are unidentified and have not been recognized at the species level, but four major kinds of pelagic larvae often are collected in ichthyoplankton surveys. Following Kendall (1979), these larvae are assigned to four subfamilies: Serraninae, Anthiinae, Epinephelinae and Grammistinae. Ken- dall (1979) described these kinds of larvae and also provided many specific iden- tifications. His work made it possible to identify much of the eastern Gulf of Mexico serranid material. METHODS AND MATERIALS A series of 13 ichthyoplankton survey cruises to the eastern Gulf of Mexico in 1971-73 provided samples from near the coast to the deep Gulf (Table 1). A total of 756 stations was sampled with a 61-cm, 505-lLm mesh bongo net in oblique tows from 200 m, or within 5 m of bottom, to surface. Houde and Chitty (1976), Houde (1977) and Houde et al. (1979) have described the survey plan, sampling methods and analytical procedures in detail. The major literature source for larval identifications was Kendall (1979). Most larvae of Diplectrum and all Centropristis larvae were assumed to be D. formosum and C. striata, respectively, based on reported adult occurrences and distributions in the eastern Gulf of Mexico (Miller 1959; Bortone, 1977). Larvae of groupers, Eipinephelus and Mycteroperca spp. usually could not be identified to genus or species, except for some large specimens of E. moria, which have distinctive dorsal and anal fin meristics (DXI, 16, 17; AlII, 9). Epinephelus mario is the most common grouper in the eastern Gulf; only the speckled hind (E. drummondhayi) has similar meristics and is known to have scattered occurrences in the area. Catches of larvae at each station were standardized to numbers under 10 m2 of sea surface (Houde 511 512 BULLETIN OF MARINE SCIENCE. VOL. 32, NO.2, 1982 Table I.

In this way mean abundances of larvae could be compared among years, seasons, depth zones and north-south sectors in the eastern Gulf. The survey area and stations that were sampled one or more times during the cruises are iUustrated in Figure l. Stations sampled on each of the cruises are not illustrated here but are illustrated in Houde et al. (1979). Comparisons of serranid larvae abun- dances between depth zones were made relative to the 50 m isobath. Comparisons between north and south sectors were made after dividing the survey area at latitude 2r15'N. Frequencies of station occurrences for common serranid larvae also were determined relative to depth zones, surface tem- peratures and surface salinities. Differences in mean abundances of larvae between depth zones and between north-south sectors were tested for significance in paired t-tests after transforming larval abundance estimates to log, (abundance ±0.0001). Differences were judged to be significant at the a '" 0.05 level. RESULTS A total of 5,350 serranid larvae was collected in the 13 cruises. Serranids ac- counted for 4.7% of all fish larvae that were collected in the eastern Gulf of Mexico and 5.2% of larvae that were identified at least to the family level. Only Clupeidae, Gobiidae, Bothidae and Myctophidae contributed more larvae than Serranidae to the collections. Serranids were among the 10 most often collected families on 8 of the 13 cruises. Serranid larvae were collected at most of the stations in the eastern Gulf, an indication that spawning is widespread in the survey area. Larvae of the four subfamilies were present in eastern Gulf collections. Larval Serraninae were most common, contributing 3,653 larvae, 68.3% of the serranid larvae collected (Table 2). There were relatively few Anthiinae (512 larvae, 9.6%), Epinephelinae (146 larvae, 2.7%) and Grammistinae (202 larvae, 3.8%). Larval serranids that could not be identified to subfamily totalled 837 (15.6%). Eleven genera and 15 species (or types) were identified in the collections (Table 2). The number of larvae identified to species (or type) was 3,977, 74.3% of the serranid larvae that were collected. The most common species was the sand perch Diplectrum formosum. Its larvae comprised 55.5% of all serranid larvae in the collections. Diplectrum formosum was the fifth most frequently collected fish larvae identified to species for the 13 cruises. Only the clupeids Sardinella an- chovia and Opisthonema oglinum, the carangid Decapterus punctatus and the bothid Syacium papillosum were more common. Other common serranid larvae were Hemanthias viva nus (red barbier), Ser- HOUDE: SERRANlD LARVAE: EASTERN GULF OF MEXICO 513 ~ + '~::=:_--:f-"" + ,;,' \ '. 10m + ,~, ,"!_... 1- '... ~\ -r\..

Unidentified species of Rypticus (soapfishes) also were common as were larvae of Serranus spp. Larval groupers (Epinephelus or Mycteroperca spp.) occurred frequently but, except for five E. morio (red grouper) larvae, they could not be identified to species. Most unidentified serranids (Table 2) probably were serran- ines, based on subfamily characters given by Kendall (1979). They were not assigned to Serraninae because of uncertainty in their identification. Numbers collected and abundances of common serranid larvae varied among cruises (Table 3). Of the eight most common serranids only D. formosum oc- curred in all cruises. Hemanthias vivanus occurred in all except one cruise and S. pumilio was present in all but two of the cruises. Although nearly eight times more D.formosum than H. viva nus larvae were collected, their mean abundances (number under 10 m2) differed by only a factor of 3.4 (Table 3), primarily because H. viva nus occurred more frequently at deeper stations. Only D. formosum and H. viva nus mean abundances exceeded 1.0 under 10 m2 for the 13 cruises.

Its mission is to identify, designate, protect and manage the ecological, recreational, research, educational, historical, and aesthetic resources and qualities of nationally significant coastal and marine areas. The existing marine sanctuaries differ widely in their natural and historical resources and include nearshore and open ocean areas ranging in size from less than one to over 5,000 square miles. Protected habitats include rocky coasts, kelp forests, coral reefs, sea grass beds, estuarine habitats, hard and soft bottom habitats, segments of whale migration routes, and shipwrecks. Because of considerable differences in settings, resources, and threats, each marine sanctuary has a tailored management plan. Conservation, education, research, monitoring and enforcement programs vary accordingly. The integration of these programs is fundamental to marine protected area management. The Marine Sanctuaries Conservation Series reflects and supports this integration by providing a forum for publication and discussion of the complex issues currently facing the National Marine Sanctuary Program. Topics of published reports vary substantially and may include descriptions of educational programs, discussions on resource management issues, and results of scientific research and monitoring projects. The series facilitates integration of natural sciences, socioeconomic and cultural sciences, education, and policy development to accomplish the diverse needs of NOAA’s resource protection mandate.

  • Phylogeny of the Epinephelinae (Teleostei: Serranidae)
    BULLETIN OF MARINE SCIENCE, 52(1): 240-283, 1993 PHYLOGENY OF THE EPINEPHELINAE (TELEOSTEI: SERRANIDAE) Carole C. Baldwin and G. David Johnson ABSTRACT Relationships among epinepheline genera are investigated based on cladistic analysis of larval and adult morphology. Five monophyletic tribes are delineated, and relationships among tribes and among genera of the tribe Grammistini are hypothesized. Generic com- position of tribes differs from Johnson's (1983) classification only in the allocation of Je- boehlkia to the tribe Grammistini rather than the Liopropomini. Despite the presence of the skin toxin grammistin in the Diploprionini and Grammistini, we consider the latter to be the sister group of the Liopropomini. This hypothesis is based, in part, on previously un- recognized larval features. Larval morphology also provides evidence of monophyly of the subfamily Epinephelinae, the clade comprising all epinepheline tribes except Niphonini, and the tribe Grammistini. Larval features provide the only evidence of a monophyletic Epine- phelini and a monophyletic clade comprising the Diploprionini, Liopropomini and Gram- mistini; identification of larvae of more epinephelines is needed to test those hypotheses. Within the tribe Grammistini, we propose that Jeboehlkia gladifer is the sister group of a natural assemblage comprising the former pseudogrammid genera (Aporops, Pseudogramma and Suttonia). The "soapfishes" (Grammistes, Grammistops, Pogonoperca and Rypticus) are not monophyletic, but form a series of sequential sister groups to Jeboehlkia, Aporops, Pseu- dogramma and Suttonia (the closest of these being Grammistops, followed by Rypticus, then Grammistes plus Pogonoperca). The absence in adult Jeboehlkia of several derived features shared by Grammistops, Aporops, Pseudogramma and Suttonia is incongruous with our hypothesis but may be attributable to paedomorphosis.

All cruise objectives were completed safely. In addition, we collected animal specimens from net tows for collaborators associated with the DEEP SEARCH project as well as collecting water samples for eDNA analysis for DEEP SEARCH and other collaborators. Water samples were also collected by a UNH undergraduate in support of her capstone paper. We were fortunate to have good weather for much of the cruise which allowed us to complete additional net tows, CTD, and fine-scale acoustic surveys at some sites (Table 1). We appreciate the excellent work of the ship’s Captain and crew (in all aspects on the boat) in helping us to accomplish our cruise objectives. Table 1. Summary of sampling that occurred at each site location during the EN615 research cruise. We were able to accomplish additional sampling at the VAC and HAT sites.

To assess the community structure of helminths and parasitic crustaceans in the splittail bass Hemanthias peruanus (Steindachner, 1875) from northern Peru. Materials and methods. 75 specimens (34 males and 41 females) of H. peruanus were captured from Puerto Cabo Blanco, Piura, Peru. Total length and sex data of the fish were recorded. For the analysis of the parasitic community, the ecological parasitological indices, aggregation indices, alpha diversity indices and association between the biometric parameters of the fish and the parasitological indices were calculated. Results. The percentage of total prevalence in splittail bass infected with at least one parasitic metazoan species was 65.33%, that is, 49 parasitized hosts. The community component of the parasitic eumetazoan fauna in the evaluated fish was dominated by the presence of ectoparasites (three species of monogeneans and one species of isopod).

  • Below the Mesophotic C
    www.nature.com/scientificreports OPEN Below the Mesophotic C. C. Baldwin1, L. Tornabene2 & D. R. Robertson3 Mesophotic coral ecosystems, which occur at depths of ~40 to 150 m, have received recent scientifc attention as potential refugia for organisms inhabiting deteriorating shallow reefs. These ecosystems merit research in their own right, as they harbor both depth-generalist species and a distinctive reef-fsh Received: 31 August 2017 fauna. Reef ecosystems just below the mesophotic are globally underexplored, and the scant recent literature that mentions them often suggests that mesophotic ecosystems transition directly into Accepted: 12 February 2018 those of the deep sea. Through submersible-based surveys in the Caribbean Sea, we amassed the most Published: xx xx xxxx extensive database to date on reef-fsh diversity between ~40 and 309 m at any single tropical location. Our data reveal a unique reef-fsh assemblage living between ~130 and 309 m that, while taxonomically distinct from shallower faunas, shares strong evolutionary afnities with them. Lacking an existing name for this reef-faunal zone immediately below the mesophotic but above the deep aphotic, we propose “rariphotic.” Together with the “altiphotic,” proposed here for the shallowest reef-faunal zone, and the mesophotic, the rariphotic is part of a depth continuum of discrete faunal zones of tropical reef fshes, and perhaps of reef ecosystems in general, all of which warrant further study in light of global declines of shallow reefs. Studies of deep tropical-reef ecosystems have surged during the past decade1–10. This is due in part to the global decline of shallow coral reefs having sparked interest in the potential for deep reefs to act as refugia for shallow-water organisms stressed by warming surface waters or deteriorating reefs.
