VARIATION in SETTLEMENT and LARVAL DURATION of Klng GEORGE WHITING, SILLAGINODES PUNCTATA (SILLAGINIDAE), in SWAN BAY, VICTORIA, AUSTRALIA
BULLETIN OF MARINE SCIENCE, 54(1): 281-296, 1994 VARIATION IN SETTLEMENT AND LARVAL DURATION OF KlNG GEORGE WHITING, SILLAGINODES PUNCTATA (SILLAGINIDAE), IN SWAN BAY, VICTORIA, AUSTRALIA Gregory P. Jenkins and Helen M. A. May ABSTRACT Otoliths were examined from late-stage larvae and juveniles of King George whiting, Sillaginodes punctata, collected from Swan Bay in spring 1989. Increments in otoliths of larval S. punctata are known to be formed daily. A transition in the microstructure of otoliths from late-stage larvae was apparently related to environmental changes associated with entry to Port Phillip Bay. The pattern of abundance of post-larvae of S. punctata in fortnightly samples supported the contention that the transition was formed immediately prior to "set- tlement" in seagrass habitats. Backcalculation to the otolith transition suggested that five cohorts had entered Swan Bay, each approximately 10 days apart, from late September to early November. Stability of this pattern for juveniles from sequential samples indicated that otolith increments continued to be formed daily in the juvenile stage. The pattern of settlement was consistent for two sites within Swan Bay. The larval phase of King George whiting settling in Port Phillip Bay was extremely long and variable, ranging from approximately 100 to 170 days. Age at settlement was more variable than length, and growth rate at settlement was I I extremely slow, approximately 0.06 mm ·d- • • Backcalculated hatching dates ranged from April to JUly. July. Increment widths in the larval stage suggest that growth slows after approxi- mately 45 to 75 days; beyond which individuals are in a slow growth, competent stage of 40 to 100 days. -

Comparisons Between the Biology of Two Species of Whiting (Sillaginidiae) in Shark Bay, Western Australia
Comparisons between the biology of two species of whiting (Sillaginidiae) in Shark Bay, Western Australia By Peter Coulson Submitted for the Honours Degree of Murdoch University August 2003 1 Abstract Golden-lined whiting Sillago analis and yellow-fin whiting Sillago schomburgkii were collected from waters within Shark Bay, which is located at ca 26ºS on the west coast of Australia. The number of circuli on the scales of S. analis was often less than the number of opaque zones in sectioned otoliths of the same fish. Furthermore, the number of annuli visible in whole otoliths of S. analis was often less than were detectable in those otoliths after sectioning. The magnitude of the discrepancies increased as the number of opaque zones increased. Consequently, the otoliths of S. analis were sectioned in order to obtain reliable estimates of age. The mean monthly marginal increments on sectioned otoliths of S. analis and S. schomburgkii underwent a pronounced decline in late spring/early summer and then rose progressively during summer and autumn. Since these trends demonstrated that opaque zones are laid down annually in the otoliths of S. analis and S. schomburgkii from Shark Bay, their numbers could be used to help age this species in this marine embayment. The von Bertalanffy growth parameters, L∞, k and to derived from the total lengths at age for individuals of S. analis , were 277 mm, 0.73 year -1 and 0.02 years, respectively, for females and 253 mm, 0.76 year -1 and 0.10 years, respectively. Females were estimated to attain lengths of 141, 211, 245 and 269 mm after 1, 2, 3 and 5 years, compared with 124, 192, 224 and 247 mm for males at the corresponding ages. -

Tagging studies have shown movement of adult fish between estuaries, but information on biological stock boundaries remains incomplete. The unknown nature of biological stock composition means no formal assessment of the entire biological stock has been completed. Separate assessments of Sand Whiting have been conducted in Queensland and New South Wales [Gray et al. 2000, Hoyle et al. 2000, Ochwada- Doyle et al. 2014, O’Neill 2000]. Here, assessment of stock status is presented at the jurisdictional level—Queensland and New South Wales. STOCK STATUS New South In New South Wales, Sand Whiting are mainly taken by the commercial Estuary Wales General Fishery (by the mesh netting and hauling sectors), with smaller catches reported by the Ocean Hauling Fishery [Hall 2015]. Annual commercial catches of Sand Whiting in NSW waters over the last five years have been well below the preceding 20 year average of 162 t [NSW DPI unpublished]. -

Memoirs of the Queensland Museum 45(1):1-164. Brisbane. ISSN 0079-8835. Published reports of protozoan species from Australian animals have been compiled into a host- parasite checklist, a parasite-host checklist and a cross-referenced bibliography. Protozoa listed include parasites, commensals and symbionts but free-living species have been excluded. Over 590 protozoan species are listed including amoebae, flagellates, ciliates and ‘sporozoa’ (the latter comprising apicomplexans, microsporans, myxozoans, haplosporidians and paramyxeans). Organisms are recorded in association with some 520 hosts including mammals, marsupials, birds, reptiles, amphibians, fish and invertebrates. Information has been abstracted from over 1,270 scientific publications predating 1999 and all records include taxonomic authorities, synonyms, common names, sites of infection within hosts and geographic locations.

The present study records the new distributional range extension for Sillago vincenti from the waters of Pichavaram mangrove, whereas earlier reports were restricted to only the Palk Bay and Gulf of Mannar regions of the Tamil Nadu coast, whereas it enjoys a wide range of distribution both in the east and west coast of India. This study marks the additional extension of the distributional record for S. vincenti in the east coast of India. Biological information on these fishes will have ecological applications particularly on account on their extreme abundance in the mangrove waters. The present study is based on the collection of specimens from handline fishing practices undertaken in the shallow waters of Pichavaram mangroves, on the southeast coast of India.

Bonham, Lighthouses of Australia. Asset Sand Islands and Shoals Description A crest of sand which rises above water level from a broad marine sand bank, forming an unstable sand island - Troubridge Island - which changes shape and size over time. The island is about 5m high at high tide, and about 2 hectares in area when inundated, but considerable larger at low tide. The island is surrounded by shallow sand embankments (Troubridge Shoals). Examples of Key Little Penguin, Black-faced Cormorant, Crested Tern and other breeding sea Species birds (numerous species) migratory wading birds (numerous species) abundant sand-dwelling invertebrates - food sources for fish and wading birds Pink Snapper King George whiting and school whiting syngnathid fishes (e.g. seahorses, pipefishes) sponges (forming “sponge gardens”, on consolidated sand) cowries; volutes and other specimen shells Knobby Argonaut (‘paper nautilus’ octopus) giant spider crab southern calamari Main Location Troubridge Island (and shallow sandbanks to the west - Troubridge Shoals) Notes Troubridge Island Conservation Park (approx. 260 hectares) was declared in 1982, and extended in 1986, partly to protect major breeding colonies of several seabird species, and provide protection for an important feeding ground used by migratory wading birds, listed under international treaties. Oceanography At the bottom of Gulf St Vincent, off the eastern “heel” of Yorke Peninsula, waters less than 20m occur up to 10km from shore. The oceanographic conditions have led to a long-term build-up of sand in some areas, including the creation of Troubridge Island, a sand island about 7km east of Sultana Point. -
